article VI, section 6 of the California Constitution.

PEOPLE v. TURNER

S154459

Opinion of the Court by Corrigan, J.

Over the course of nearly 12 years, a serial killer raped

and murdered women in high crime areas of Los Angeles. Police

identified defendant Chester Dewayne Turner as a suspect in

2003, when his DNA was found to match DNA left on the victims

in several unsolved cases. Convicted of murdering ten women

and one viable fetus, he was sentenced to death. (Pen. Code,

§ 187, subd. (a).)1 This automatic appeal primarily challenges

the admission of statistical evidence about the significance of

the DNA matches and hearsay testimony about the fetus’s

viability. The hearsay claim has merit and warrants reversal of

the fetal murder conviction. The judgment is affirmed in all

other respects.

I. BACKGROUND

A. Guilt Phase

1. Figueroa Corridor Murders

Between 1987 and 1996, the bodies of eight women were

found in the Figueroa Corridor of Los Angeles, an area beset by

crime, including prostitution and narcotics activity. Defendant

All statutory references are to the Penal Code unless

otherwise stated. Defendant was convicted of second degree

murder for the fetus, but all other murders were in the first

degree. The jury also found true special circumstance

allegations of multiple murder and, as to one of the victims,

murder in the course of a rape. (§ 190.2, subd. (a)(3), (17).)

lived at various addresses in the Figueroa Corridor during this

period. All of the victims had been sexually assaulted and

strangled to death, sometimes by ligature and sometimes

manually. All had a history of drug abuse, and all but one had

cocaine in their systems. Some were homeless; some were

thought to be mentally ill; and some had arrests for prostitution.

a. 1987 to 1989

The body of 21-year-old Diane Johnson was found on

March 9, 1987, in a construction area six blocks from

defendant’s home. Drag marks led to her body, which was nude

from the waist down. She had been strangled.

Annette Ernest, age 26, was found just three blocks away

on October 29, 1987. She lay face down with her pants lowered.

There was a possible ligature mark on her neck and a bite on

one breast. The cause of death was strangulation.

On January 20, 1989, a young boy discovered the body of

31-year-old Anita Fishman in an alley less than two blocks from

defendant’s home. Her pants were partially down and the body

was beginning to decompose. She died of manual strangulation.

Regina Washington was 27 years old and visibly pregnant

when she was killed. Her body was found on September 23,

1989, lying on a mattress in a burnt-out garage about 14 blocks

from defendant’s home. Although she was clothed, her pants

were unfastened and her shirt pulled up. A black coaxial cable

was wrapped around her throat and attached to an electrical box

on a nearby wall. She died of ligature strangulation with signs

of a struggle. Washington’s female fetus weighed 825 grams

with a gestational age of 27 to 28 weeks. That weight and age

were considered viable under World Health Organization

guidelines. Despite her mother’s cocaine use, the fetus had no

PEOPLE v. TURNER

Opinion of the Court by Corrigan, J.

congenital abnormalities and appeared to be developing

normally. She died from lack of oxygen due to her mother’s

strangulation.2

b. 1993 to 1996

On April 2, 1993, 29-year-old Andrea Tripplett was found

dead behind an abandoned house 22 blocks from defendant’s

residence and only two blocks from her own home. Her skirt

was pushed up and she was naked below the waist. She was

around five months pregnant when she was manually strangled

to death. At 305 grams, the fetus was not yet viable.

Deserae Jones, who sometimes went by Tracy Williams,

was also 29 years old and killed by manual strangulation. Her

body was found on May 16, 1993 in the trash-filled yard of a

burned, boarded-up house within 30 blocks of defendant’s

address. She was unclothed below the waist.

On February 12, 1995, Natalie Price’s body was found

approximately five blocks from defendant’s home, next to an

empty house where people gathered to smoke narcotics. Her bra

was pushed up around her neck and her pants were pulled

down. She had been strangled and struck on the head. She was

39 years old when she died.

Mildred Beasley, age 45, was on her way to her sister’s

house when she disappeared. Her body was found on November

6, 1996 on a trash-strewn embankment of the 110 Freeway

about 18 blocks from defendant’s home. The area was

frequented by transients and known for drug activity. She had

been strangled to death and left naked below the waist, with her

upper garments pulled up. Insect activity indicated the body

had begun to decompose.

2. Downtown/Skid Row Murders in 1998

Two additional murder victims were found under similar

circumstances near downtown Los Angeles in 1998. During that

year, defendant lived downtown at the Regal Hotel on 6th

Street.

Paula Vance, age 41, was found dead on February 3, 1998.

Her body lay next to an abandoned building near 6th and Hope

Street, about 14 blocks from defendant’s residence. Her upper

garments were pulled up, her nylons and underwear pulled

down. She had been strangled, and there were signs of sexual

assault. A surveillance camera at the scene recorded her

entering the alleyway with a man, who grabbed her around the

neck until she fell to the ground. Vance was the only murder

victim without cocaine in her system. Evidence showed that she

was homeless and suffered from mental illness.

On April 6, 1998, the body of 37-year-old Brenda Bries was

found in a portable toilet on South Gladys Avenue and 5th

Street, just 50 yards from defendant’s residence. She was

slumped with her head on the seat, pants around her knees, and

shirt pulled around her neck. A fabric cord, intertwined with

her bra, was wrapped around her neck. She died from ligature

strangulation and showed signs of a struggle.

3. Investigation

Crime scene investigators compiled and stored sexual

assault kits for all victims.

4

PEOPLE v. TURNER

Opinion of the Court by Corrigan, J.

a. 2002 Rape of Maria M.

In March 2002, defendant raped Maria M., a 47-year-old

homeless woman who worked as a prostitute and sold drugs.

She knew defendant from the Midnight Mission, a shelter they

both frequented. As she walked alone near the shelter one

night, defendant asked to borrow her lighter, which he used to

smoke cocaine. Instead of returning the lighter, defendant

grabbed Maria in a chokehold and dragged her behind some

dumpsters, where he raped and sodomized her, ejaculating in

the process. He threatened to kill her if he was arrested.

Maria immediately went to a police station, but after being

kept waiting for some time she felt ignored and left. The next

morning, she reported the assault to Midnight Mission

employees and the police. Defendant attempted to flee but was

arrested at the shelter. Evidence for a sexual assault kit was

collected at a hospital. Defendant ultimately pled no contest to

rape by force or fear and unlawful penetration. (§§ 261,

subd. (a)(2), 289, subd. (a)(1).)

b. DNA Identification of Defendant

i. General Evidence

Gary Sims, a director of the Department of Justice DNA

Laboratory, testified as an expert on forensic DNA analysis.

Chromosomes found in cell nuclei contain DNA, which is the

same in all cells of a person’s body. The vast majority of human

DNA is the same, coding basic traits all people share. At some

chromosomal regions, however, the DNA is highly variable.

Forensic DNA analysis studies these areas of variation. The

specific site being studied is called a “locus.” “Allele” describes

the alternative forms of genetic material at a particular locus.

Each locus has two alleles, one inherited from each parent.

5

PEOPLE v. TURNER

Opinion of the Court by Corrigan, J.

Current forensic testing focuses on loci with sections of DNA

that repeat a variable number of times, known as short tandem

repeats or STRs. Different people have different numbers of the

repeating sequence at these sites. DNA testing compares the

alleles at these sites to see if they are the same or different. As

the science of DNA analysis developed, more loci with variable

STRs could be tested. At the time of defendant’s trial, analysts

could study DNA variation at 13 different loci. Sims explained

that DNA analysis is a powerful tool in determining “the

probability of identity,” which is the likelihood that two people

chosen at random will have the same DNA sequences at the

areas tested.

Once DNA is extracted from biological material left at a

crime scene, the STR regions are amplified. Analysts determine

the number of STR repeats for alleles present at each of the 13

loci, producing a “profile” for the evidence sample. Biological

material is then obtained from a suspect to create a DNA profile.

When the two profiles are compared, a match is declared if the

alleles at all loci are the same. The significance of a match

depends on how common the particular DNA profile is in the

population. Sims explained that population databases have

been developed to determine how frequently particular alleles

are found in each major ethnic group. After the allele

frequencies are determined at each locus, the frequencies are

multiplied together to determine the rarity of the overall profile.

This number, called the random match probability, reflects the

probability that DNA from a randomly chosen person would

match the evidence profile.

6

PEOPLE v. TURNER

Opinion of the Court by Corrigan, J.

ii. Case-specific Evidence

On July 3, 2002, defendant gave cheek swabs for DNA

testing in connection with Maria’s assault. The Los Angeles

Police Department (LAPD) DNA Unit prepared defendant’s

DNA profile from this reference sample. His profile matched the

DNA in sperm cells recovered during Maria’s examination.

Investigators later compared defendant’s profile with

DNA samples from unsolved crimes.3 Defendant’s profile

matched DNA left on all of the victims here. A private forensic

laboratory, Orchid Cellmark (Cellmark), retested the evidence

and independently confirmed LAPD’s findings. Specifically, the

laboratories found as follows.

Sperm cell DNA matching defendant’s profile was

recovered from anal and vaginal swabs from Diane Johnson. In

the Anita Fishman, Regina Washington, Andrea Tripplett,

Natalie Price, Mildred Beasley, Paula Vance, and Brenda Bries

cases, DNA from sperm cells in vaginal swabs matched

defendant’s profile. Occasionally these samples included some

“carryover” DNA from the victim’s epithelial cells, but there

were no other sperm cell contributors. Cellmark also found

DNA with defendant’s profile in external genital swabs from

Price, Beasley, Vance, and Bries, and in the anal swabs for

Beasley and Bries. In the Annette Ernest and Deserae Jones

cases, sperm cell DNA recovered from the external genital area

matched defendant’s profile. Cellmark also found DNA with

defendant’s profile in nipple and anal swabs in the Ernest case

and in oral and anal swabs in the Jones case. Some external

3

The profile used in this analysis was obtained from a blood

sample defendant submitted after his rape conviction. (See

§ 1202.1, subd. (a).)

7

PEOPLE v. TURNER

Opinion of the Court by Corrigan, J.

genital samples included DNA from unknown individuals, but

in all such cases defendant was the primary contributor. Each

unknown DNA profile appeared in only one victim. Defendant’s

DNA profile alone recurred in all of the victims.

Both laboratories declared a match when DNA sequences

were the same at all 13 sites examined. LAPD’s DNA Unit

determined the probability of this match occurring at random

was one in one quintillion. Cellmark calculated the probability

of a random match within the Black population group as one in

6.725 quintillion. A quintillion is rendered as a one followed by

18 zeroes.

4. Defense Case

A third forensics laboratory analyzed the DNA evidence

for the defense. Unlike the other two laboratories, Technical

Associates (TA) used the Y-STR test, which isolates male DNA

by studying sites on the Y chromosome. Because it examines

only male lineage, the Y-STR test is less powerful than other

tests, producing random match probabilities of one in thousands

versus one in quadrillions. It is useful, however, when the

amount of male DNA in a sample is comparatively small.

TA tested samples from all of the victims except Anita

Fishman, examining 12 loci on the Y chromosome. Defendant

was considered identified when his DNA profile matched most,

if not all, of the 12 loci in the sample DNA. Rather than

describing a correspondence between defendant’s profile and the

sample as a “match,” the TA criminalist preferred to state that

defendant could not be excluded as the source of DNA in the

sample. Because genes examined by the Y-STR test are less rare

than those in other tests, it was possible another male’s profile

could overlap defendant’s at some sites.

8

PEOPLE v. TURNER

Opinion of the Court by Corrigan, J.

TA found DNA consistent with defendant’s profile in

samples from each of the victims studied. Specifically, DNA

consistent with defendant’s was found: in the nipple and

vaginal swabs from Diane Johnson; in the nipple, vaginal, and

anal swabs from Annette Ernest; in the external genital swab

from Regina Washington; in the anal swab from Andrea

Tripplett; in the nipple and anal swabs from Deserae Jones; in

the external genital, nipple, and anal swabs from Natalie Price;

in the nipple and anal swabs from Mildred Beasley; in the

external genital and nipple swabs from Paula Vance; and in the

external genital swab from Brenda Bries. The Y-STR test

detected male DNA from unknown contributors in several of the

samples. No DNA profile other than defendant’s repeated from

victim to victim.

The defense expert testified that sperm cells deposited in

the vagina are typically expelled within one to two days from a

living woman. After death, however, bodily processes slow down

the expulsion. Sperm cells could remain as long as two weeks

postmortem. Sperm found in a female who had been deceased

for a day could have been deposited three or four days earlier.

Even if defendant’s DNA profile was detected at a higher

concentration than unknown profiles, the finding did not mean

defendant was necessarily the last person to deposit DNA.

The parties stipulated that the defense requested

discovery of DNA test results for all clothing booked into

evidence and that neither side conducted such testing.

B. Penalty Phase

1. Aggravating Evidence

The prosecution presented victim impact evidence relating

to seven victims. The jury heard from Annette Ernest’s mother,

9

PEOPLE v. TURNER

Opinion of the Court by Corrigan, J.

Andrea Tripplett’s mother, Anita Fishman’s mother and

younger sister, Deserae Jones’s mother and niece, Regina

Washington’s daughter, Natalie Price’s daughter, and Mildred

Beasley’s younger sister and niece. They described the families’

sorrow at losing their loved ones and their anguish at having the

cases remain unsolved for so many years.

Most of the aggravating evidence concerned defendant’s

violent conduct in four unrelated incidents: murder, sexual

assault, felony resisting arrest, and threatening a sheriff’s

deputy while awaiting trial on the current charges. The

prosecution also presented evidence of defendant’s conviction for

the attack on Maria M.

a. Murder of Elandra Bunn

In June 1987, less than three months after Diane

Johnson’s murder, Elandra Bunn was killed in the Figueroa

Corridor. Her body had been left in an alley near 88th Street

and Figueroa. Her pants had been pulled down to her ankles.

She had “massive facial trauma” and multiple abrasions. The

injuries were consistent with her face being pushed or dragged

across a rough surface. She died of strangulation, likely

manual. Bunn had a history of cocaine abuse, and the drug was

found in her system. She was in the early stages of pregnancy.

Crime scene investigators compiled a sexual assault kit.

Although it was destroyed in 1996, some evidence was retained,

including a bloody tissue found four or five feet from the body.

DNA obtained from the tissue matched defendant’s profile, with

a random match probability of one in one quintillion.

b. Sexual Assault of Carla W.

After midnight in October 1996, 22-year-old Carla W. was

walking alone in downtown Los Angeles. A man grabbed her by

10

PEOPLE v. TURNER

Opinion of the Court by Corrigan, J.

the arm and crotch. He tried to pull her into a nearby alley but

she struggled and screamed. When a patrol car drove by, he

fled. Later that night, Carla identified defendant as her

attacker and did so again in court.

c. Resisting Arrest

In March 1997, the police tried to interview defendant

about a possible parole violation. When two officers came to his

motel room, defendant answered the door but refused to put his

hands behind his head for a weapons check. Officers attempted

to handcuff him but he ran, dragging the officers 10 to 20 yards

down a hallway and into the parking lot. Kicking one officer

several times in the chest and leg, he tried to grab the officer’s

gun, then broke free and fled. When a search dog alerted near

a woodpile, the officers ordered defendant to emerge. He rose

from his hiding place then hit the search dog with a nearby

fiberglass sink. The dog bit him in response. Defendant ran at

the officers, charging ahead even after being struck with six

rounds from a beanbag shotgun. Following another violent

struggle, defendant was finally taken into custody.

d. Threatening a Deputy

In May 2006, while in county jail awaiting trial, defendant

confronted Deputy Natalie Uyetatsu, the only female deputy

assigned to his area. Angry because Uyetatsu had put him on

lockdown, defendant told another inmate he would kill Uyetatsu

if he was found guilty of the pending charges. The inmate

thought the threat was serious because defendant seemed to

hate women.

2. Mitigating Evidence

Defendant’s mother, Audrey Turner, described his

upbringing. She raised defendant alone from the time he was a

11

PEOPLE v. TURNER

Opinion of the Court by Corrigan, J.

year old. She worked full time while a friend watched her son.

They moved from Arkansas to California when defendant was

four. He was a fun-loving child but struggled in school, often

getting into trouble. Defendant went to live with his father in

Arkansas but returned after a year. His father provided no

financial or emotional support.

When defendant was 14, Ms. Turner had a second son,

Anthony. Soon thereafter she began working a second job.

Friends helped with babysitting until Ms. Turner’s father

arrived to help in 1984. Defendant eventually dropped out of

high school and worked as a pizza delivery driver. When he was

17, his mother insisted he leave the home due to his drinking

and drug use, but she let him return while he recovered from a

gunshot injury. During that time, defendant treated his mother

well. He helped her with her cleaning job and cooked and

cleaned for the family.

In 1991, Ms. Turner moved to Salt Lake City. Anthony

stayed behind to finish the school year, then joined his mother.

Each summer, Anthony stayed in California with defendant,

who was his primary caretaker. Defendant warned his brother

to stay in school and keep out of trouble.

Defendant had four children who loved him. He was

unable to support them because he was often in custody. His

mother helped raise the children in Salt Lake City.

II. DISCUSSION

A. Pretrial Issues

1. DNA Issues

The court denied defendant’s pretrial motion under People

v. Kelly (1976) 17 Cal.3d 24 (Kelly) to exclude evidence about the

DNA matches and their statistical significance. Defendant now

12

PEOPLE v. TURNER

Opinion of the Court by Corrigan, J.

makes two related arguments concerning this ruling. First, he

contends the court erred in admitting random match probability

numbers because this statistic is not a generally accepted

measure of significance in “cold hit”4 DNA cases. (See Kelly, at

p. 30.) Building on this argument, defendant next asserts that

insufficient evidence supports the guilt verdicts because the jury

heard no evidence of the rarity of his DNA profile. The first

argument was rejected in People v. Nelson (2008) 43 Cal.4th

1242 (Nelson). Defendant does not persuade us that Nelson was

wrongly decided. Defendant’s second argument fails because, as

Nelson and other cases have explained, random match

probability is an expression of a DNA profile’s rarity in the

population. Because the jury was given this statistic, it was able

to evaluate the probative value of the DNA matches in

determining his guilt.

a. Background

“Forensic DNA analysis is a comparison of a person’s

genetic structure with crime scene samples to determine

whether the person’s structure matches that of the crime scene

sample such that the person could have donated the sample.”

4

A “cold hit case,” sometimes called a “trawl case,”

colloquially refers to a case in which “the DNA match itself made

the defendant a suspect, and the match was discovered only by

searching through a database of previously obtained DNA

samples.” (Donnelly & Friedman, DNA Database Searches and

the Legal Consumption of Scientific Evidence (1999) 97 Mich.

L.Rev. 931, 932.) Cold hit cases may be contrasted with

traditional “confirmation cases,” in which other types of

evidence pointed to the defendant as a suspect and warranted

testing his DNA against crime scene samples. (Ibid.; see Kaye,

Rounding Up the Usual Suspects: A Legal and Logical Analysis

of DNA Trawling Cases (2009) 87 N.C. L.Rev. 425, 428 (Kaye).)

13

PEOPLE v. TURNER

Opinion of the Court by Corrigan, J.

(Nelson, supra, 43 Cal.4th at pp. 1257–1258.) As discussed,

scientists examine specific loci that are highly variable among

individuals. A match is declared when DNA sequences in the

samples being compared are identical at all loci. Here,

prosecution experts found matches between defendant’s DNA

and crime scene DNA for each victim at 13 different loci.

Defendant does not dispute the accuracy of this part of the

analysis.

“Once a match is found, the next question is the statistical

significance of the match.” (Nelson, supra, 43 Cal.4th at

p. 1258.) This number helps the jury evaluate how much weight

it should give to evidence of a match. A match would be of little

significance if the genetic profile were shared by many others in

the population. (People v. Venegas (1998) 18 Cal.4th 47, 82

(Venegas).) The concept is frequently explained in terms of “how

unlikely it is that the crime scene samples came from a third

party who had the same DNA pattern as the suspect.” (People

v. Barney (1992) 8 Cal.App.4th 798, 809 (Barney).) In other

words, the question is: “Given that the suspect’s known sample

has satisfied the ‘match criteria,’ what is the probability that a

person chosen at random from the relevant population would

likewise have a DNA profile matching that of the evidentiary

sample?” (People v. Soto (1999) 21 Cal.4th 512, 523 (Soto).) The

smaller the odds that a match could be found at random in the

relevant population, the greater the evidentiary weight of a

suspect’s match. (Venegas, at p. 82.)

“Experts use a statistical method called the ‘product rule’

to calculate the rarity of the sample in the relevant population.”

(Nelson, supra, 43 Cal.4th at p. 1259.) We have discussed this

calculation in detail previously and need only summarize it

here. In short, examiners first determine the frequency of

14

PEOPLE v. TURNER

Opinion of the Court by Corrigan, J.

alleles at each locus using population databases, then multiply

the frequencies of all loci together, generating a statistic that

reflects the probability that an individual will have the complete

profile across all loci studied. (Ibid.; Soto, supra, 21 Cal.4th at

p. 525.) As in other cases involving a match across many loci,

application of the product rule here produced “astronomical

odds” (Nelson, at p. 1259): one in one quintillion according to

the LAPD expert, and one in 6.725 quintillion according to the

Cellmark expert. Earth’s total population at the time of trial

was around six and a half billion people.

Under the Kelly test, when expert testimony relies on “ ‘a

new scientific technique,’ ” the proponent must establish “that

the technique is ‘ “sufficiently established to have gained

general acceptance in the particular field to which it belongs” ’

(quoting Frye [v. United States (D.C. Cir. 1923)] 293 F. [1013,]

1014, italics omitted).” (Venegas, supra, 18 Cal.4th at p. 76; see

Kelly, supra, 17 Cal.3d at p. 30.) Reliability need not be

relitigated in every case. “[O]nce a trial court has admitted

evidence based upon a new scientific technique, and that

decision is affirmed on appeal by a published appellate decision,

the precedent so established may control subsequent trials, at

least until new evidence is presented reflecting a change in the

attitude of the scientific community.” (Kelly, at p. 32.)

We have considered whether evidence calculated by the

product rule satisfies Kelly’s reliability requirement in several

cases. Venegas held that a modified version of the product rule

known as the interim ceiling principle was “ ‘artificially

conservative,’ ” yet it was a generally accepted method for

calculating the significance of a DNA match while also

compensating for any possible effect caused by population

substructuring. (Venegas, supra, 18 Cal.4th at p. 89; see

15

PEOPLE v. TURNER

Opinion of the Court by Corrigan, J.

Barney, supra, 8 Cal.App.4th at pp. 814–816.)5 Soto determined

concerns about population substructuring had been laid to rest

by later scientific developments and held that use of the

unmodified product rule is generally accepted in the relevant

scientific community as a means of expressing the significance

of a DNA match. (Soto, supra, 21 Cal.4th at pp. 515–516.) Most

recently, Nelson held that the admissibility of evidence based on

the product rule in a cold hit case “is a question of relevance, not

scientific acceptance,” thus obviating the need for a Kelly

inquiry. (Nelson, supra, 43 Cal.4th at p. 1260.) We further held

that the product rule provides relevant and admissible evidence

in cold hit cases. (Ibid.)

b. Admissibility of Random Match

Statistics

Defendant was initially identified as a suspect based on

cold hits in the state’s database of convicted offenders.6

5

In the early days of forensic DNA analysis, population

geneticists were concerned that nonrandom mating within

subgroups would undermine the product rule’s assumption that

alleles at different loci were statistically independent. (See

Barney, supra, 8 Cal.App.4th at p. 815.)

6

No information about the database search was presented

at trial. In an early court appearance, the prosecutor explained

how defendant was identified. When DNA samples preserved

from various unsolved cases were uploaded to the state’s

offender database, defendant’s profile was found to match crime

scene evidence in the Beasley and Vance cases. After learning

of the matches, investigators identified approximately 25

unsolved murder cases with preserved biological evidence that

appeared to be sexually motivated killings of women in the

geographic region where defendant “either lived, worked[,] or

was known to associate.” DNA evidence from these cases was

then uploaded to the database, and eight more matches were

made to defendant’s profile. The Attorney General argues this

16

PEOPLE v. TURNER

Opinion of the Court by Corrigan, J.

Renewing the arguments we rejected in Nelson, he claims the

random match probability statistic generated by the product

rule does not accurately convey the significance of a DNA match

derived from searching an offender database. He also disputes

the relevance of this statistic in the cold hit context. Because

defendant insists Nelson was wrongly decided, we discuss that

case in some detail.

Nelson was identified as a suspect when DNA evidence

from a 26-year-old murder was uploaded to the state’s offender

database. (Nelson, supra, 43 Cal.4th at pp. 1248–1249.)

Further testing confirmed the database match. (Id. at p. 1249.)

At Nelson’s trial, the prosecution expert testified that the 15-loci

match profile would occur at random in only one in 950 sextillion

African-Americans, one in 130 septillion Caucasians, or one in

930 sextillion Hispanics. (Ibid.)7 Challenging these statistics,

Nelson conceded the product rule is a generally accepted method

for calculating the odds of a random match when a suspect’s

DNA is compared to crime scene evidence. (See Soto, supra, 21

Cal.4th at p. 541.) But he argued scientists disagree as to

whether the method is an appropriate way to assess the

significance of a match when the suspect is not identified at

random but is instead found through a database search.

is not a pure cold hit case because the second database search

was conducted after other evidence pointed to defendant as a

suspect. Even so, we address defendant’s arguments because it

is clear the initial identification was based exclusively on a

database match.

7

The LAPD DNA Unit did not report random match

probabilities broken down by racial population subgroups.

Defendant does not argue this omission was error, nor does he

contend the distinction alters Nelson’s force as precedent here.

17

PEOPLE v. TURNER

Opinion of the Court by Corrigan, J.

(Nelson, at pp. 1259–1260.) Defendant makes the same

argument here.

The challenges are premised on the idea that reported

statistics should avoid “ ‘ascertainment bias,’ ” which can result

when repeated testing of a hypothesis imbues a particular result

with more significance than it warrants. (Kaye, supra, 87 N.C.

L.Rev. at p. 454.) For example, while the odds of winning a

lottery are very small, a winner will likely be found if everyone

who actually bought a lottery ticket is considered. (See 4

Faigman et al., Modern Scientific Evidence: The Law and

Science of Expert Testimony (2019–2020 ed.) § 30:20) “The

probability [of winning], while remote, is not impossible, and

looking in a pool of people, rather than just picking a person at

random, affects the likelihood that you will find what you are

looking for.” (Ibid.) Ascertainment bias also describes “the bias

that exists when one searches for something rare in a set

database.” (U.S. v. Jenkins (D.C. 2005) 887 A.2d 1013, 1018–

1019 (Jenkins).)8 In the DNA context, for example, “if the

frequency of a given profile is expected to occur in 1 out of every

100,000 people, the chances of finding a match increase if one

searches a database with 50,000 entries versus a database with

only 10 entries.” (Jenkins, at p. 1018, fn. 8.)

Four methods have been proposed for expressing the

statistical significance of a match following a database search.

Only three need be considered here.9 One method, the random

One proposal is not a statistical calculation but a different

approach to testing. The first National Research Council report

on forensic DNA analysis suggested ascertainment bias could be

Opinion of the Court by Corrigan, J.

match probability statistic, is calculated by the unmodified

product rule, which calculates the rarity of a match in the

population. (Nelson, supra, 43 Cal.4th at p. 1261; see Soto,

supra, 21 Cal.4th at pp. 515–516.) An alternative proposal

begins with the rarity of the profile in the general population,

the statistic generated by the product rule, then multiplies that

number by the number of profiles in the database searched.

(Nat. Research Council, DNA Technology in Forensic Science

(1996) pp. 134–135.) The result reflects the probability of

finding a match in a particular database and is frequently called

the database match probability. (See Nelson, at p. 1262;

Jenkins, supra, 887 A.2d at p. 1020.) By definition, it will

always be a larger number than the rarity statistic alone, and

thus more favorable to the defendant. The last approach, often

called the Balding-Donnelly or Bayesian method, differs from

the others in its premise that a database match is more

significant than a confirmatory match. This model reasons that

a database search not only identifies a match but also

“simultaneously eliminates other profiles as being the source of

avoided by using one set of loci to identify a suspect in a

database and then examining a different set of loci to confirm

the match. (Nat. Research Council, DNA Technology in

Forensic Science (1992) p. 124.) Because this approach would

use fewer loci than actually matched in determining

significance, product rule calculations would result in shorter,

perhaps “unnecessarily conservative,” odds. (Nelson, supra, 43

Cal.4th at p. 1261.) Defendant does not challenge Nelson’s

observation that this approach “ ‘is no longer accepted or

followed by the relevant scientific community.’ ” (Id. at p. 1262,

quoting Jenkins, supra, 887 A.2d at p. 1022, fn. 17.)

19

PEOPLE v. TURNER

Opinion of the Court by Corrigan, J.

the sample,” thus increasing the likelihood the identified person

is the actual source. (Jenkins, at p. 1020.)10

After reviewing these different approaches, Nelson

observed that while there was “some disagreement among

experts as to which of these methods is the best, i.e., the most

probative, way to judge the significance of a cold hit” from a

database search, “the question before us is not what technique

is ‘best,’ but whether use of the product rule in a cold hit case is

permissible.” (Nelson, supra, 43 Cal.4th at p. 1263.) The

product rule had already been approved as a reliable method for

calculating the rarity of a DNA profile in the relevant population

(see Soto, supra, 21 Cal.4th at pp. 515–516), and we observed

that the rule’s use in a cold hit case did not convert it into a new

scientific technique requiring further Kelly scrutiny. (Nelson, at

pp. 1263–1264.) On the contrary, the real questions here

10

Professor Kaye illustrates this reasoning by contrasting a

database trawl with a hypothetical drug company that conducts

20 clinical trials and achieves success in only one, but then

reports that one success “as if there had been no search.” (Kaye,

supra, 87 N.C. L.Rev. at p. 469.) In the drug trial context, “the

omitted information contradicts the company’s claim of

therapeutic effectiveness. In contrast, if all the other clinical

trials were consistent with the company’s claim, the failure to

mention them would not prejudice the case for approving the

drug. The trawl case is similar to a series of successful clinical

trials . . . . The additional evidence — that everyone else in the

database is excluded — is consistent with the claim of

defendant’s guilt. The lack of other hits in the database trawl

therefore has an effect opposite to that of the lack of other

significant differences in the clinical trials. It supplies

compatible rather than contradictory data.” (Ibid., italics

added.) According to this reasoning, ascertainment bias is not

a problem that needs correction in database search cases. (Id.

at pp. 469–472.)

20

PEOPLE v. TURNER

Opinion of the Court by Corrigan, J.

concern relevance, not the reliability of methodology. (Id. at

p. 1264.) As the Jenkins court explained: “At the heart of this

debate is a disagreement over the competing questions to be

asked, not the methodologies used to answer those questions.

The rarity statistic, the database match probability, and the

Bayesian approach each answer unique and potentially relevant

questions. More importantly, there is no controversy in the

relevant scientific community as to the accuracy of the various

formulas. In other words, the math that underlies the

calculations is not being questioned. Each approach to

expressing significance of a cold hit DNA match accurately

answers the question it seeks to address. The rarity statistic

accurately expresses how rare a genetic profile is in a given

society. Database match probability accurately expresses the

probability of obtaining a cold hit from a search of a particular

database. Bayesian analysis accurately expresses the

probability that the person identified through the cold hit is the

actual source of the DNA in light of the fact that a known

quantity of potential suspects was eliminated through the

database search. These competing schools of thought do not

question or challenge the validity of the computations and

mathematics relied upon by the others. Instead, the arguments

raised by each of the proponents simply state that their

formulation is more probative, not more correct. Thus, the

debate . . . is one of relevancy, not methodology . . . .” (Jenkins,

supra, 887 A.2d at pp. 1022–1023, fn. omitted, italics added; see

Nelson, at p. 1264.)

Relevant evidence is that “having any tendency in reason

to prove or disprove any disputed fact.” (Evid. Code, § 210.)

Generally, all relevant evidence is admissible unless otherwise

provided by statute. (Evid. Code, § 351.) If admitted, the trier

21

PEOPLE v. TURNER

Opinion of the Court by Corrigan, J.

of fact determines the weight it gives to that evidence. Two

sources of relevant evidence may potentially conflict or lead to

opposite conclusions. Evidence may be relevant but found

unpersuasive. A jury hearing competing relevant evidence will

ultimately have to determine what weight, if any, to give each.

“Relevance” describes whether evidence should be heard

because it might reasonably resolve a dispute. “Weight”

describes the degree to which the jury finds the evidence

probative.

“Relevancy is a legal issue for courts to answer.” (Nelson,

supra, 43 Cal.4th at p. 1265.) While deference to scientists is

appropriate on scientific questions, determining the relevance of

evidence “ ‘is a hallmark responsibility of the trial judge and

that responsibility is not appropriately delegated to parties

outside the court.’ (Jenkins, supra, 887 A.2d at p. 1025.)” (Id.

at p. 1265.) Nelson concluded the statistical rarity of the DNA

profile, calculated by the product rule, is relevant in cold hit

cases. (Id. at p. 1267.) We see no basis to depart from that

conclusion. To be sure, a defendant remains free to present

evidence that the product rule statistic should be given less

weight because some experts have concerns about its persuasive

value due to ascertainment bias. But defendant did not attempt

to do so here, nor did he offer evidence of an alternative measure

of statistical significance, such as database match probability.11

11

Nelson left open the possibility that database match

probability might also be admissible in an appropriate case.

(Nelson, supra, 43 Cal.4th at p. 1267, fn. 3.) Defendants may

indeed seek to introduce such evidence, particularly in cases

where the database searched was especially large. As with the

other measures of statistical significance, the trial court may, of

course, consider an Evidence Code section 352 objection that the

i. Applicability of the Kelly Test

Defendant first asserts that Nelson misapplied California

law because, contrary to Venegas and Soto, the court exempted

a category of DNA statistics from Kelly analysis despite an

ongoing scientific controversy. This argument misconstrues

both our prior precedents and Nelson’s holding. The issue in

Venegas and Soto was whether the product rule was a reliable

measure of a DNA profile’s rarity or whether some modification

was needed to account for population substructuring and other

issues. But, critically, both the unmodified product rule and the

modified ceiling approach are statistical formulae designed to

answer the same question: How frequently can we expect a

specific profile to appear in the relevant population? As

discussed, the alternative statistical models proposed for cold

hit cases are each answering a different question. We adhere to

the view that admissibility of the random match statistic in

these cases presents an issue of relevance, not scientific

reliability.

Defendant argues Nelson misconstrued the scientific

debate. He contends the issue is not one of legal relevance but

of science, because the various methodologies all seek to answer

the question: What is the correct way to statistically account for

ascertainment bias? Defendant merely repeats the arguments

made in Nelson. It is evident that experts disagree about what

information would be most helpful to the factfinder in

evaluating a cold hit DNA match. Frequentists believe juries

should be told the probability of finding a match in the offender

relevance of the database match probability statistic is

outweighed by a substantial possibility of juror confusion or

undue consumption of time.

23

PEOPLE v. TURNER

Opinion of the Court by Corrigan, J.

database because the database trawl makes the match to the

defendant less significant. (See Kaye, supra, 87 N.C. L.Rev. at

p. 460.) Bayesians believe the database match itself “has

considerable probative value” and does not reduce the

significance of the match to the defendant. (Id. at p. 471.) But,

as Nelson observed, the dispute among these statisticians

concerns not which information is correct, but which

information is “the best, i.e., the most probative, way to judge

the significance of a cold hit.” (Nelson, supra, 43 Cal.4th at

p. 1263.) Relevance, and hence admissibility, is a question for

the court. (Id. at p. 1265.) Probative value, or weight, is an issue

for the jury to decide.

Defendant’s renewed arguments do not persuade us that

a Kelly hearing was required. He cites no case agreeing with his

position. It appears all published decisions considering the

issue have concluded the product rule statistic is admissible in

cold hit cases without a Kelly hearing or the equivalent. (See

U.S. v. Davis (D.Md. 2009) 602 F.Supp.2d 658, 676–677;

Commonwealth v. Bizanowicz (2011) 459 Mass. 400, 407–409

[945 N.E.2d 356, 362–363]; State v. Bartylla (Minn. 2008) 755

N.W.2d 8, 20; Jenkins, supra, 887 A.2d at pp. 1023–1025; see

also Crews v. Johnson (W.D.Va. 2010) 702 F.Supp.2d 618, 639

[opining that database match probability should also have been

admitted, but finding no error in admission of product rule’s

rarity statistic because it was “clearly probative of guilt”].)

Indeed, the Massachusetts Supreme Judicial Court

persuasively observed that excluding evidence of the rarity

statistic would eviscerate the purpose for which offender

databases have been created. (Bizanowicz, at p. 408.) “DNA

evidence from convicted offenders whose DNA is stored in a

CODIS [(Combined DNA Index System)] database could never

24

PEOPLE v. TURNER

Opinion of the Court by Corrigan, J.

be used at trial unless it was obtained without using the CODIS

database.” (Id. at pp. 408–409.)

Nor are we persuaded that the denial of a Kelly hearing

was erroneous because of the trial court’s reasoning. The court

found it significant that the database match here was confirmed

by later testing, comparing the cold hit to a confidential

informant who initiates the investigation of a particular subject.

Similar reasoning appeared in People v. Johnson (2006) 139

Cal.App.4th 1135, where the Court of Appeal observed that a

“database search merely provides law enforcement with an

investigative tool, not evidence of guilt.” (Id. at p. 1150.)

Reasoning that proof of guilt depends upon the confirmatory

match between a defendant’s profile and that of the perpetrator,

the court concluded a defendant’s initial identification “as a

possible suspect based on a database search simply does not

matter.” (Id. at p. 1151.) The trial court disclaimed reliance on

Johnson, which was not yet final at the time of its ruling.

Nevertheless, defendant argues Johnson was wrongly decided

and could not properly support denial of a Kelly hearing. We

need not consider the validity of Johnson’s holding. Our task is

to review the trial court’s ruling, not its reasoning. “ ‘No rule of

decision is better or more firmly established by authority, nor

one resting upon a sounder basis of reason and propriety, than

that a ruling or decision, itself correct in law, will not be

disturbed on appeal merely because given for a wrong reason. If

right upon any theory of the law applicable to the case, it must

be sustained regardless of the considerations which may have

moved the trial court to its conclusion.’ ” (D’Amico v. Board of

Medical Examiners (1974) 11 Cal.3d 1, 19.) The court’s ruling

here was sound.

25

PEOPLE v. TURNER

Opinion of the Court by Corrigan, J.

ii. Relevance of the Profile’s Rarity

Defendant also disagrees with Nelson’s holding that the

generally accepted product rule statistic is relevant in cold hit

cases. Our discussion of this issue relied heavily on Jenkins,

supra, 887 A.2d 1013. First, Nelson agreed with Jenkins that

“in a non-cold-hit case, the number derived from the product

rule ‘represents two concepts: (1) the frequency with which a

particular DNA profile would be expected to appear in a

population of unrelated people, in other words, how rare is this

DNA profile (“rarity statistic”), and (2) the probability of finding

a match by randomly selecting one profile from a population of

unrelated people, the so-called “random match probability.” ’

(Jenkins, [] at p. 1018.)” (Nelson, supra, 43 Cal.4th at p. 1266.)

The government in Jenkins had conceded that when a match is

the result of a database search, the number derived from the

product rule is no longer an accurate expression of the

probability of finding a matching profile by chance. (Ibid.; see

Jenkins, at p. 1018 & fn. 7.) This is essentially the same

argument defendant makes here. Even accepting the

government’s concession that random match probability was not

an applicable principle in cold hit cases, Jenkins explained that

the “same product rule number . . . still accurately expresses the

rarity of the DNA profile.” (Jenkins, at p. 1018, fn. 7.) Although

the database search might alter the probability of finding a

match, it does not change how rare a specific profile is among

humans. (See Nelson, at pp. 1266–1267; Jenkins, at pp. 1018–

1019.) We held that this expression of rarity is relevant in cold

hit cases just as it is when the defendant has been identified by

other means. (Nelson, at p. 1267.)

Defendant contends the rarity statistic loses all relevance

when there has been a database search. That argument fails.

26

PEOPLE v. TURNER

Opinion of the Court by Corrigan, J.

In light of “modern DNA technology and statistical methods,”

the rarity of a matching profile is relevant no matter how the

suspect was first located. (Nelson, supra, 43 Cal.4th at p. 1267.)

If a profile is extremely rare, as is increasingly likely the more

loci are examined, “[i]t is relevant for the jury to know that most

persons of at least major portions of the general population could

not have left the evidence samples.” (People v. Wilson (2006) 38

Cal.4th 1237, 1245.) The rarity of the evidence profile has a

tendency to prove that the defendant, who has a matching

profile, was the source of the evidence at the crime scene. This

test for relevance is met regardless of how the defendant was

first identified. The product rule statistic “refer[s] to the

perpetrator’s profile and [is] therefore . . . unaffected by any

particular defendant or suspect.” (People v. Xiong (2013) 215

Cal.App.4th 1259, 1274 (Xiong).) It informs the jury “how few

people are likely to have this profile.” (Ibid.) The product rule

statistic therefore provides relevant evidence, although its

admissibility, as with all relevant evidence, may be subject to an

Evidence Code section 352 analysis.

Defendant contends random match probability is not

relevant in cold hit cases because a match resulting from a

database search is not “random.” Whereas random match

probability is appropriate if only one person is tested, defendant

insists the statistic is inapt when a potentially large number of

profiles are tested in a database trawl. This argument focuses

on the odds of finding a match in a database, relying on the

assertion that the more profiles are compared against the

evidence sample, the greater the likelihood a match will

ultimately be found. The assertion may be accurate, but it does

not assist defendant here. If a suspect’s profile is compared to a

database of 10, it may be quite unlikely that the suspect’s profile

27

PEOPLE v. TURNER

Opinion of the Court by Corrigan, J.

will happen to match one of those 10 profiles. But if the

database is expanded to 10,000, the chances of a successful

match increase because there are more opportunities for a

match. That the opportunities for a match increase as the

database size grows does not mean the database trawl itself

injects error, nor does it cast doubt on the fact that the suspect’s

DNA has been found to match crime scene evidence.

When the random match probability statistic is very

small, such as the one in one quintillion figure calculated by the

LAPD’s DNA Unit in this case, the probability of finding a match

in an offender database will generally not be germane to an

issue the jury must decide.12 In such cases, the relevance of

asking how likely it is that someone in the database committed

the crime is eclipsed by the issue of how likely it is that someone

other than the defendant could have been the source of the

evidence samples. This latter question is addressed by a

statistic that measures the prevalence of a DNA profile in the

entire population of potential suspects. (See Xiong, supra, 215

Cal.App.4th at pp. 1274–1275.) Thus, the statistic generated by

the product rule, which describes the rarity of the DNA profile

12

We reaffirm, however, that trial courts have discretion to

permit evidence of database match probability in an appropriate

case. Database match probability is relevant in some

circumstances. For example, a profile’s random match

probability may be relatively high if a degraded crime scene

sample provides only a few loci for testing. In such a case, there

is a significant chance that a “match” based on those few loci

could be found in a large database by coincidence, even though

the individual had nothing to do with the crime. (Chin et al.,

Forensic DNA Evidence: Science and the Law (The Rutter

Group 2019) § 5:4.) Database match probability is a way of

conveying this concept.

28

PEOPLE v. TURNER

Opinion of the Court by Corrigan, J.

shared by the perpetrator and the defendant, is relevant even in

cold hit cases. (Chin et al., Forensic DNA Evidence: Science and

the Law, supra, § 5:4.) Of course, defendants remain free to

challenge the probative value of this statistic through

objections, cross-examination, or the introduction of other

evidence, such as database match probability, and trial courts

may give clarifying jury instructions when appropriate.

c. Sufficiency of Evidence Regarding DNA

Profile Rarity

Building on his previous arguments, defendant claims

insufficient evidence supports the verdicts because the jury only

heard evidence of random match probability, not rarity. It is

true that the prosecution experts typically described statistical

significance in terms of “the probability of a random match of

unrelated individuals.” But this information did convey

essential facts about the significance of the matches between

defendant’s profile and crime scene DNA. The rarity of a DNA

profile and random match probability are two different ways of

expressing the meaning of the same statistic calculated using

the product rule, and it is ultimately the statistic that is

relevant. (See Nelson, supra, 43 Cal.4th at p. 1266.) Defendant

incorrectly asserts that Nelson disapproved use of random

match probability in cold hit cases. Nelson recited the Jenkins

court’s observation that “ ‘the product rule number no longer

accurately expresses the random match “probability” ’ ” in cold

hit cases. (Nelson, at p. 1266, quoting Jenkins, supra, 887 A.2d

at p. 1018, fn. 7.) But the statement simply acknowledged that

the defendant in a cold hit case has been identified by a database

search and not selected “at random.” Although the concept of

“random match probability” is not directly applicable when the

defendant has been identified by a database search, and the

29

PEOPLE v. TURNER

Opinion of the Court by Corrigan, J.

defendant may point this out at trial, the statistic generated by

the product rule continues to have relevance in cold hit cases

because it expresses rarity. Nelson did not suggest otherwise.

On the contrary, Nelson held, and we reaffirm, that the statistic

generated by the product rule provides relevant and admissible

evidence in cold hit as well as confirmatory match cases.

(Nelson, at pp. 1266–1267.)13

Here, one expert told the jury that the probability a

random person, unrelated to defendant, would match DNA left

at each crime scene was one in one quintillion. Another expert

set the probability at one in 6.725 quintillion. Even though

phrased in “random match” language, the point of these product-

rule-derived statistics was clearly to convey the rarity, if not

uniqueness, of the 13-loci profile. The evidence was properly

admitted and constitutes substantial evidence in support of the

verdicts.

2. Excusal of Prospective Jurors for Cause

Defendant next argues two prospective jurors were

improperly dismissed from the venire based on their views about

the death penalty. The dismissals were permissible.

Criminal defendants have a constitutional right to an

impartial jury, and “a prospective juror’s personal views

13

Trial courts and parties have tools available to address

any possible confusion arising from the use of “random match”

terminology in cold hit cases. If there is a risk jurors might

mistakenly think the defendant was identified at random,

rather than from a database search, the concept can be clarified

through cross-examination, additional evidence, and/or jury

instructions. Defendant did not object on this ground below, nor

did he seek to present evidence about the database searches by

which he was located.

30

PEOPLE v. TURNER

Opinion of the Court by Corrigan, J.

concerning the death penalty do not necessarily afford a basis

for excusing the juror for bias.” (People v. Martinez (2009) 47

Cal.4th 399, 425 (Martinez).) Instead, consistent with the

constitutional imperative, prospective jurors may be dismissed

for cause only if their views on capital punishment “ ‘would

“ ‘prevent or substantially impair’ ” the performance of [their]

duties as defined by the court’s instructions and [their] oath.’

(People v. Cunningham (2001) 25 Cal.4th 926, 975; see

Wainwright v. Witt (1985) 469 U.S. 412, 424; Witherspoon v.

Illinois (1968) 391 U.S. 510, 521–522.)” (People v. Winbush

(2017) 2 Cal.5th 402, 424 (Winbush).) A prospective juror’s bias

against the death penalty need not be shown with unmistakable

clarity. (People v. Abilez (2007) 41 Cal.4th 472, 497.) “Jurors

commonly supply conflicting or equivocal responses to questions

directed at their potential bias or incapacity to serve.”

(Martinez, at p. 426.) Indeed, “many prospective jurors ‘simply

cannot be asked enough questions to reach the point where their

bias has been made “unmistakably clear”; these [prospective

jurors] may not know how they will react when faced with

imposing the death sentence, or may be unable to articulate, or

may wish to hide their true feelings.’ ” (People v. Beck and Cruz

(2019) 8 Cal.5th 548, 607 (Beck and Cruz).) Nevertheless, a

dismissal for cause is appropriate if, “after examining the

available evidence, . . . the trial court [is] left with a definite

impression that the prospective juror is unable or unwilling to

faithfully and impartially follow the law.” (People v. Thompson

(2016) 1 Cal.5th 1043, 1066 (Thompson).)

Our review in this area is necessarily deferential because

“the trial court, through its observation of the juror’s demeanor

as well as through its evaluation of the juror’s verbal responses,

is best suited to reach a conclusion regarding the juror’s actual

31

PEOPLE v. TURNER

Opinion of the Court by Corrigan, J.

state of mind.” (People v. Jones (2012) 54 Cal.4th 1, 41; see

Uttecht v. Brown (2007) 551 U.S. 1, 7.) In applying deferential

review, “appellate courts recognize that a trial judge who

observes and speaks with a prospective juror and hears that

person’s responses (noting, among other things, the person’s

tone of voice, apparent level of confidence, and demeanor),

gleans valuable information that simply does not appear on the

record.” (People v. Stewart (2004) 33 Cal.4th 425, 451 (Stewart).)

Accordingly, the trial court’s determination as to the juror’s true

state of mind is binding on appeal if supported by substantial

evidence. (Thompson, supra, 1 Cal.5th at p. 1066; Martinez,

supra, 47 Cal.4th at pp. 426–427.)

a. Prospective Juror No. 4

In her jury questionnaire, Prospective Juror No. 4 said she

was moderately in favor of the death penalty, and her responses

evinced a general willingness to impose death in an appropriate

case. When asked to consider this particular case, however, the

juror’s confidence faltered. The questionnaire asked whether,

depending on the evidence and circumstances presented, jurors

could impose the death penalty in a case involving a multiple

murder allegation. Instead of circling “yes” or “no,” Prospective

Juror No. 4 wrote “possibly.” The court probed this response in

voir dire, asking whether the juror could impose the death

penalty in a case involving allegations of multiple murder and

murder in the course of a rape. She responded, “I’d have to hear

everything,” and “I am open.” However, after the court finished

its question with the phrase “could you actually vote for death,”

Prospective Juror No. 4 said, “I would not vote for death.” The

questioning continued:

“THE COURT: I’m sorry. You would not?

32

PEOPLE v. TURNER

Opinion of the Court by Corrigan, J.

“PROSPECTIVE JUROR NO. 4: No. I’d have to listen to

everything and, you know, get an understanding and the good

and the bad and all of that.

“THE COURT: All right.

“PROSPECTIVE JUROR NO. 4: And it would be a hard

decision to say now.

“THE COURT: There are some people that believe in the

death penalty, support it but cannot participate in the process.

“PROSPECTIVE JUROR NO. 4: Right.

“THE COURT: Is that you? You could not vote for death,

no matter what the evidence is in the penalty phase?

“PROSPECTIVE JUROR NO. 4: Possibly, yeah.”

Later in voir dire, the prosecutor explained that there is

no burden of proof at the penalty phase, but jurors must make

“a moral decision and . . . a choice.” She then asked Prospective

Juror No. 4 about her ability to make such a choice:

“MS. DO: And so given some of the reluctance that I’m

seeing in you, knowing that it’s a choice, do you think that if you

have the option of giving a person, a human being[,] life without

parole, that you would always choose that?

“PROSPECTIVE JUROR NO. 4: I have a hard time

putting someone to death. Most likely my choice would be the

life in prison.

“MS. DO: Okay.

“PROSPECTIVE JUROR NO. 4: I would have a hard

time with the other.

33

PEOPLE v. TURNER

Opinion of the Court by Corrigan, J.

“MS. DO: All right. So do you think that you might, if

we get to penalty phase, walk in predisposed to life without

parole?

“PROSPECTIVE JUROR NO. 4: Most likely, yes.

“MS. DO: Okay. And would the prosecution have quite a

burden to prove to you that death would be appropriate to

overcome that predisposition?

“PROSPECTIVE JUROR NO. 4: Yeah.”

In granting the prosecution’s motion to dismiss

Prospective Juror No. 4, the court remarked that it had noticed

the juror’s “body language as she was answering the questions,

and she seemed to be very tightly drawn, is what I would say.

That’s a bad description, but not open and free with her feelings

about it but somewhat defensive about it.” Although the juror

had said on the questionnaire that she could “possibly” impose

the death penalty, in oral questioning she made it “awfully

clear,” in the court’s opinion, that she would not actually do so.

Based on the juror’s demeanor and responses in voir dire, the

court concluded “she would not fairly impose the death penalty.”

Substantial evidence supports this decision. Although the

juror may have supported the death penalty in theory, her voir

dire responses made it clear she felt great reluctance about

actually voting to impose it. We considered a similar record in

People v. Solomon (2010) 49 Cal.4th 792 (Solomon). There, we

deferred to the trial court’s finding of substantial impairment

regarding a prospective juror who expressed support for the

death penalty in her questionnaire but later equivocated about

whether she could ultimately vote to sentence someone to death.

(Id. at pp. 835–836.) Similarly, in People v. Cunningham, supra,

25 Cal.4th at page 981, we upheld the dismissal of a prospective

34

PEOPLE v. TURNER

Opinion of the Court by Corrigan, J.

juror who said “she believed in the death penalty and would like

to see it applied more often but was not certain whether

personally she could vote for it.”

Deference to the court’s finding of substantial impairment

is particularly appropriate here because the court expressly

based its ruling, in part, on the juror’s “tightly drawn” and

“defensive” body language. (See People v. Manibusan (2013) 58

Cal.4th 40, 73.) This demeanor, combined with the juror’s

repeatedly expressed doubts about whether she could impose a

death sentence, could support a “definite impression” that the

juror would be unwilling or unable “to faithfully and impartially

apply the law.” (Wainwright v. Witt, supra, 469 U.S. at p. 426;

see People v. Nunez and Satele (2013) 57 Cal.4th 1, 24.)

Stewart, supra, 33 Cal.4th 425 does not compel a different

result. There, we held it was error to dismiss jurors based solely

on brief written comments and a check mark next to a box

indicating their views “would either ‘prevent or make it very

difficult’ ” to impose the death penalty. (Id. at p. 446.) Here, the

court and prosecutor explored Prospective Juror No. 4’s views in

greater detail. While it is true that a prospective juror is not

disqualified merely because she would find it difficult to impose

the death penalty (id. at pp. 446–447), Prospective Juror No. 4’s

responses to oral questioning indicated not only that she would

have difficulty with the decision but also that she would be

predisposed to voting for a life sentence, regardless of the

evidence presented. Nor is this case like People v. Pearson

(2012) 53 Cal.4th 306, 332, in which the court improperly

dismissed a prospective juror who had no strong views on the

death penalty and gave no indication she would be unable to

perform her duty as a capital juror. The juror’s responses here

indicated she would not be able to impartially apply the law.

35

PEOPLE v. TURNER

Opinion of the Court by Corrigan, J.

b. Prospective Alternate Juror No. 1

Prospective Alternate Juror No. 1’s questionnaire

responses consistently expressed personal opposition to capital

punishment.14 He checked a box indicating he was strongly

against the death penalty and wrote, “I’m not for death penalty”

in response to the question whether he would always vote guilty

to reach the penalty phase in a capital case. He wrote that he

was “not sure” what purpose the death penalty serves and that

he did not feel it should be used. When asked whether he could

impose the death penalty in a case involving multiple murder,

the juror circled “yes” and wrote, “I will perform my civi[c] duty

but I’m not for it.” He reported that his religious organization

was “anti death penalty” and, though he felt obligated to accept

that view, he could “do what I’m ask[ed] to do” regardless of his

views. Finally, he agreed somewhat that people who

intentionally kill should never get the death penalty, explaining,

“I’m not for the death of anyone.”

In voir dire, the court asked whether Prospective

Alternate Juror No. 1 would always vote against the death

penalty, regardless of the evidence. The juror responded, “Not

always, but I’d say if it was on a scale, it would be more towards

life than death.” When the court asked if he was open to voting

for death, the juror said, “If I have to, . . . I will follow the

instructions,” but in his “personal view,” he “would lean towards

life.” When pressed about whether he could realistically ever

see himself voting for death, the juror responded, “Not really,”

14

Because an alternate juror was selected at random and

seated early in the trial, it does not appear that any error in this

excusal would have been harmless. (See People v. Bryant, Smith

and Wheeler (2014) 60 Cal.4th 335, 399, fn. 19.)

36

PEOPLE v. TURNER

Opinion of the Court by Corrigan, J.

and “it would be kind of tough for me.” Nevertheless, he stated

that he could perform his duty as a juror and could vote for death

if the penalty was warranted.

The prosecutor asked whether, given his religious and

moral opposition to the death penalty, Prospective Alternate

Juror No. 1 could “make a decision that would end a man’s life.”

The juror responded, “I’m not sure if I could do that,” adding

that he might not be able to vote for death if the defendant’s

family members were present. The prosecutor explained that

there might be family members in the audience but asked again

whether, regardless of family members, the juror could vote for

death.15 Again, he answered, “I’m not sure.”

The court granted the prosecutor’s cause challenge.

Although the juror said he would “do his duty,” the court found

his answers indicated he would not be able to vote for death,

“especially if there were any people in the courtroom related to

the defendant.” As with Prospective Juror No. 4, this dismissal

is supported by substantial evidence. We recently upheld the

dismissal of a prospective juror who expressed similar doubts

about her ability to impose the death penalty. (Beck and Cruz,

supra, 8 Cal.5th at p. 607.) When a prospective juror repeatedly

says he does not know whether he could realistically impose the

death penalty, we will not second-guess the trial court’s

15

Defendant argues it was “improper” for the prosecutor to

probe the juror’s ability to announce a death verdict in front of

family members. We have repeatedly approved similar lines of

questioning. (See People v. Lynch (2010) 50 Cal.4th 693, 734;

People v. Bramit (2009) 46 Cal.4th 1221, 1235; People v.

Samayoa (1997) 15 Cal.4th 795, 853–854.)

determination that the juror is substantially impaired. (See id.

at pp. 607–608; Solomon, supra, 49 Cal.4th at pp. 835–836.)

B. Guilt Phase Issues

1. Third Party Culpability Evidence

Defendant argues the court infringed his constitutional

right to present a defense when it excluded evidence about police

efforts in the Washington case to match a partial shoe print with

a different suspect. The ruling was an appropriate exercise of

discretion.

Shortly before trial, defense counsel announced he

intended to introduce evidence that police had compared a

partial footprint found on Regina Washington’s shirt to the shoe

of another individual. The court deferred ruling, noting

admissibility would depend on the print’s significance in

relation to the crime scene. Trial evidence established that a

partial shoe print outline had been found on the back shoulder

of Washington’s white T-shirt. At an Evidence Code section 402

hearing, a criminalist testified that the shoe print was

approximately one square inch and “of a quality that no further

comparison could be made.” He had compared the print to a

shoe belonging to Ray Anthony Williams and could not

eliminate the shoe as the source of the print. Mr. Williams was

connected to the case by unspecified hearsay evidence, which

was not made part of the record. The prosecution sought to elicit

evidence about the size and quality of the print but argued the

defense should be precluded from inquiring about the Williams

comparison under Evidence Code section 352.16

16

Evidence Code section 352 provides: “The court in its

discretion may exclude evidence if its probative value is

38

PEOPLE v. TURNER

Opinion of the Court by Corrigan, J.

The court agreed the evidence would be irrelevant and

inadmissible. It explained, “[T]he problem is this: By making

the comparison, it suggests to the jury that there was a reason

for the comparison, which is hearsay, which is not admissible.

[¶] So you can’t get the reason for doing the comparison in front

of the jury.” The court also denied defendant’s request to ask

more generally whether the print had been compared “to

anybody else” to eliminate them as a suspect, explaining that

the print “doesn’t include or eliminate because it’s not sufficient

to do that. And . . . bringing forth the fact of the comparison, it

suggests that there is more than the actual evidence in the case,

which is the reason for it, which is hearsay.” Defendant now

contends he had a constitutional right to present evidence of the

Williams comparison because it tended to show a third party

committed the Washington murder.

Like all other evidence, third party culpability evidence

may be admitted if it is relevant and its probative value is not

substantially outweighed by the risk of undue delay, prejudice,

or confusion, or otherwise made inadmissible by the rules of

evidence. (Evid. Code, §§ 350, 352; see People v. Hall (1986) 41

Cal.3d 826, 834 (Hall).) “To be admissible, the third-party

evidence need not show ‘substantial proof of a probability’ that

the third person committed the act; it need only be capable of

raising a reasonable doubt of defendant’s guilt. At the same

time, we do not require that any evidence, however remote, must

be admitted to show a third party’s possible culpability.” (Hall,

substantially outweighed by the probability that its admission

will (a) necessitate undue consumption of time or (b) create

substantial danger of undue prejudice, of confusing the issues,

or of misleading the jury.”

39

PEOPLE v. TURNER

Opinion of the Court by Corrigan, J.

at p. 833.) For example, “evidence of mere motive or opportunity

to commit the crime in another person, without more, will not

suffice to raise a reasonable doubt about a defendant’s guilt

. . . .” (Ibid.) Moreover, admissible evidence of this nature

points to the culpability of a specific third party, not the

possibility that some unidentified third party could have

committed the crime. (See People v. Page (2008) 44 Cal.4th 1,

39 (Page); People v. Panah (2005) 35 Cal.4th 395, 481; People v.

Gutierrez (2002) 28 Cal.4th 1083, 1136.) For the evidence to be

relevant and admissible, “there must be direct or circumstantial

evidence linking the third person to the actual perpetration of the

crime.” (Hall, at p. 833, italics added.) As with all evidentiary

rulings, the exclusion of third party evidence is reviewed for

abuse of discretion. (See People v. Lewis (2001) 26 Cal.4th 334,

372–373 (Lewis); People v. Kaurish (1990) 52 Cal.3d 648, 686.)

The court properly excluded evidence about the shoe print

comparison. No direct or circumstantial evidence linked

Williams to the Washington murder. Defendant insists the

evidence would have shown that “someone else was present at

the scene [and] was responsible for the murder.” But the

evidence could establish no such thing. The one-inch print was

deficient in quality and size to be matched to any particular

shoe. This deficiency would have made it impossible to exclude

any number of shoes as the source of the mark. The criminalist’s

inability to exclude Williams as the source of the print was

therefore irrelevant and potentially misleading, to the extent

the jury might have speculated the result indicated an

affirmative identification. Defendant contends forensic

evidence linking a third party to a crime scene is always

admissible, but the premise of his argument fails. The shoe

print did not affirmatively link Williams, defendant, or anyone

40

PEOPLE v. TURNER

Opinion of the Court by Corrigan, J.

else to the murder. Nor was it relevant that the police had

compared the shoe print to a third party, since the comparison

yielded no “direct or circumstantial evidence linking [him] to the

actual perpetration of the crime.” (Hall, supra, 41 Cal.3d at

p. 833.) We have repeatedly upheld the exclusion of third party

culpability evidence when the third party’s link to a crime is

tenuous or speculative. (See, e.g., Page, supra, 44 Cal.4th at

pp. 38–39; Lewis, supra, 26 Cal.4th at p. 373; People v. Alcala

(1992) 4 Cal.4th 742, 792–793.) The linkage here is similarly

unsupported.

Furthermore, as the trial court noted, testimony about the

comparison would have invited speculation about why Williams

was being investigated. Yet no explanation could be provided

because the evidence about Williams’s potential as a suspect

was inadmissible hearsay. The court reasonably concluded the

shoe print evidence would have been irrelevant and potentially

confusing without this additional information. Although the

court did not expressly invoke Evidence Code section 352 as the

basis for its ruling, it clearly had the concerns of that statute in

mind when excluding the evidence. Moreover, express reliance

on section 352 is not required because we must affirm if the

court’s ruling is correct on any ground. (People v. Geier (2007)

41 Cal.4th 555, 582.)

Defendant also claims exclusion of the evidence violated

his constitutional rights to due process, compulsory process, and

“to present a complete defense.” (California v. Trombetta (1984)

467 U.S. 479, 485.) There was no constitutional error. “As a

general matter, the ordinary rules of evidence do not

impermissibly infringe on the accused’s right to present a

defense.” (Hall, supra, 41 Cal.3d at p. 834; see United States v.

Scheffer (1998) 523 U.S. 303, 308.) This case is no exception.

41

PEOPLE v. TURNER

Opinion of the Court by Corrigan, J.

The court’s reasonable application of the rules of evidence to

exclude irrelevant and potentially misleading information did

not deprive defendant of his constitutional rights. (See Lewis,

supra, 26 Cal.4th at p. 373–374; People v. Cudjo (1993) 6 Cal.4th

585, 611.)

2. Issues Regarding Fetal Viability

Defendant was charged with murdering the fetus carried

by Regina Washington. In 1989, when this crime was

committed, the murder statute had consistently been

interpreted to require a finding of fetal viability. (See People v.

Davis (1994) 7 Cal.4th 797, 804–805, 812 (Davis).)

Dr. Lisa Scheinin, a deputy medical examiner with the Los

Angeles County Coroner’s Office, testified on that topic.

Although she had not autopsied the fetus herself, Dr. Scheinin

related findings from an autopsy report that the fetus was

female, weighed 825 grams, and had a gestational age of 27 to

28 weeks, or approximately six and a half months. She

explained that World Health Organization guidelines consider a

fetus viable after it has reached the 22nd week or a weight of

500 grams. Although the autopsy report said nothing specific

about whether the fetus could have survived outside the womb,

Dr. Scheinin concluded from the numbers in the report that it

was “clearly well into the range that’s defined as viable.” The

fetus had no congenital abnormalities, and there was nothing to

suggest Washington’s cocaine use had negatively affected its

health or development. Based on the autopsy report’s findings,

the fetus appeared to be a “normally developing healthy baby.”

a. Fetal Viability Instruction

Defendant first contends the jury instruction defining

viability was erroneous and violated his rights to due process, a

42

PEOPLE v. TURNER

Opinion of the Court by Corrigan, J.

fair trial, and a fair and reliable penalty determination. The

claim fails because the instruction accurately conveyed the legal

definition of viability.

The jury was instructed with a modified version of

CALJIC No. 8.10: “In the crime of murder, a human fetus is

defined as a viable unborn child. Viability is defined as the

capability of the fetus to maintain independent existence

outside of the womb even if this existence required artificial

medical aid.”17 Defendant did not object or propose an

alternative instruction.

In 1970, the Legislature amended section 187,

subdivision (a), to include the killing of a fetus within the

definition of murder. (Stats. 1970, ch. 1311, § 1, p. 2440; Davis,

supra, 7 Cal.4th at p. 803.) Thereafter, the United States

Supreme Court decided in the abortion context that states have

no legitimate interest in protecting a fetus before it reaches

viability, which the court defined as the “capability of

meaningful life outside the mother’s womb.” (Roe v. Wade (1973)

410 U.S. 113, 163; see Davis, at p. 803.) A series of Court of

Appeal decisions relying on Roe held that only the killing of a

viable fetus could constitute murder. (See People v. Smith

(1976) 59 Cal.App.3d 751, 757 (K.A. Smith); People v. Apodaca

(1978) 76 Cal.App.3d 479, 487, 489 (Apodaca); People v. Smith

(1987) 188 Cal.App.3d 1495, 1514 (R.P. Smith); see also Davis,

at pp. 804–805.) We disapproved this line of cases in 1994 when

17

The 1988 version of the instruction in effect at the time of

the Washington murder was similar. It said: “A viable human

fetus is one who has attained such form and development of

organs as to be normally capable of living outside of the uterus.”

(CALJIC No. 8.10 (5th ed. 1988).)

43

PEOPLE v. TURNER

Opinion of the Court by Corrigan, J.

we held that viability is not required for the crime of murdering

a fetus. (Davis, at p. 810.) However, our decision was

prospective only. (Id. at p. 812.) Accordingly, when defendant

was tried, a conviction for murdering the Washington fetus

required a finding that the fetus was viable.

Courts first defined viability for this purpose as “ ‘having

attained such form and development of organs as to be normally

capable of living outside the uterus.’ ” (K.A. Smith, supra, 59

Cal.App.3d at p. 758.) The definition was later expanded to

address the availability of medical assistance. Apodaca, supra,

76 Cal.App.3d at page 489 stated that “a fetus is deemed viable

when it is possible for it to survive the trauma of birth, although

with artificial medical aid.” Similarly, R.P. Smith, supra, 188

Cal.App.3d at page 1514 summarized case law as holding that

“viability means being capable of surviving the trauma of birth

with the aid of normal medical science.” The instruction here

was fully consistent with the controlling law. It defined viability

as the fetus’s capability to live outside the womb, even if doing

so required medical assistance.

Nevertheless, defendant complains the instruction was

comparable to one we found lacking in Davis. The comparison

does not withstand scrutiny. The instruction at issue in Davis

stated that “ ‘a fetus is viable when it has achieved the capability

for independent existence; that is, when it is possible for it to

survive the trauma of birth, although with artificial medical

aid.’ (Italics added.)” (Davis, supra, 7 Cal.4th at p. 813.) We

found the term “possible” to be problematic because it could

permit a finding of viability for a fetus that was “incapable of

survival outside the womb for any discernible time.” (Id. at p.

814.) Because the term significantly lowered the viability

threshold as it was commonly accepted at the time, we

44

PEOPLE v. TURNER

Opinion of the Court by Corrigan, J.

concluded this modification of CALJIC No. 8.10 was error.

(Davis, at p. 814.) By contrast, the instruction in defendant’s

trial used no variant of the word “possible,” nor did it include

any similar language that could have lowered the threshold for

when a fetus becomes viable. The instruction required that a

viable fetus have the “capability . . . to maintain independent

existence outside of the womb even if this existence required

artificial medical aid.” (Italics added.) The word “maintain”

excludes a case in which the fetus might only survive

momentarily. Even assuming defendant did not forfeit his claim

by failing to object, the instruction given here accurately defined

viability and did not violate defendant’s constitutional rights.

b. Hearsay Evidence of Viability

After we notified the parties of our intention to set the case

for oral argument, defendant filed a supplemental brief

contending Dr. Scheinin violated state law by relating case-

specific hearsay from the fetus’s autopsy report to support her

viability opinion.18 (See People v. Sanchez (2016) 63 Cal.4th 665

(Sanchez).) He also argued the report’s statements were

testimonial and admitted in violation of his Sixth Amendment

right to confront his accusers. (See Crawford v. Washington

(2004) 541 U.S. 36.) Because we conclude the state law error

was prejudicial and requires reversal of the fetal murder

conviction, we need not address these constitutional

arguments.19 It is not reasonably possible the error affected the

18

He also sought judicial notice of the autopsy report and its

attachments. We granted this unopposed request. (See Evid.

Code, §§ 452, subds. (c), (h), 459, subd. (a).)

19

Whether a challenged statement is hearsay is always the

threshold question. If it is, it cannot be admitted unless it

satisfies an exception. If it does not do so, and the error is

45

PEOPLE v. TURNER

Opinion of the Court by Corrigan, J.

jury’s penalty decision, however, and defendant’s death

sentence remains undisturbed. (See People v. Gonzalez (2006)

38 Cal.4th 932, 960-961 (Gonzalez); see also Chapman v.

California (1967) 386 U.S. 18, 24 (Chapman).)

i. Hearsay

Hearsay is “evidence of a statement that was made other

than by a witness while testifying at the hearing and that is

offered to prove the truth of the matter stated.” (Evid Code,

§ 1200, subd. (a).) “Documents like letters, reports, and

memoranda are often hearsay because they are prepared by a

person outside the courtroom and are usually offered to prove

the truth of the information they contain.” (Sanchez, supra, 63

Cal.4th at p. 674.) Hearsay evidence is generally inadmissible

unless it satisfies a statutory exception. (Evid. Code, § 1200,

subd. (b).)

As noted, Dr. Scheinin did not perform the autopsy on

Regina Washington’s fetus. She did, however, relate to the jury

observations recorded by the non-testifying medical examiner,

including the weight and gestational age of the fetus. These

facts were hearsay if offered to prove their truth. (See Sanchez,

supra, 63 Cal.4th at p. 674.) Experts enjoy wide latitude in the

sources they may draw upon, and they are permitted to rely on

hearsay in reaching their conclusions. (Id. at pp. 685–686;

People v. Leon (2015) 61 Cal.4th 569, 603; see Evid. Code, § 802.)

That is to say, experts can take hearsay into account when

forming their own opinions.20 “What an expert cannot do,”

prejudicial under state law, a further Crawford analysis is

unnecessary. (See Sanchez, supra, 63 Cal.4th at p. 680.)

20

Experts may also tell the jury about background

information generally accepted and reasonably relied on in their

46

PEOPLE v. TURNER

Opinion of the Court by Corrigan, J.

however, “is relate as true case-specific facts asserted in hearsay

statements, unless they are independently proven by competent

evidence or are covered by a hearsay exception.” (Sanchez, at

p. 686.) Some prior cases had allowed experts to relate case-

specific facts on the theory that the material was not offered for

its truth, but merely to show the basis of the expert’s opinion.

Sanchez pointed out the flaw in this logic: “When an expert

relies on hearsay to provide case-specific facts, considers the

statements as true, and relates them to the jury as a reliable

basis for the expert’s opinion, it cannot logically be asserted that

the hearsay content is not offered for its truth. In such a case,

‘the validity of [the expert’s] opinion ultimately turn[s] on the

truth’ (Williams[ v. Illinois (2012)] 567 U.S. [50,] 108 . . . (conc.

opn. of Thomas, J.)) of the hearsay statement. If the hearsay

that the expert relies on and treats as true is not true, an

important basis for the opinion is lacking.” (Sanchez, at

pp. 682–683.)21 When Dr. Scheinin gave facts about gestational

field. This information is part of the expert’s specialized

knowledge, even if derived from hearsay sources. (See Evid.

Code, §§ 801, subd. (b), 802; Sanchez, supra, 63 Cal.4th at

p. 676; see also Simons, Cal. Evidence Manual (2020) § 4:31.)

On the distinction between case-specific facts and general

background information, see Sanchez at pages 676 to 677.

21

Defendant raised no hearsay or confrontation objection

below. Although his case was tried after Crawford established

a constitutional ban on testimonial hearsay, the statements in

question would not have been considered hearsay at all under

the law then in effect because they were offered for the “non-

hearsay purpose” of explaining the basis for Dr. Scheinin’s

opinion. (See People v. Montiel (1993) 5 Cal.4th 877, 918–919

(Montiel), overruled in Sanchez, supra, 63 Cal.4th at p. 686,

fn. 13.) Drawing on United States Supreme Court precedent,

particularly Williams v. Illinois, supra, 567 U.S. 50, Sanchez

rejected that approach. (See People v. Perez (2020) 9 Cal.5th 1,

47

PEOPLE v. TURNER

Opinion of the Court by Corrigan, J.

age and weight obtained only from the autopsy report, presented

them to the jury as true, and represented that those facts

bolstered her opinion, she related case-specific hearsay. (See

Sanchez, at p. 685.)

The Attorney General concedes the testimony was hearsay

but argues the report could have been admitted under an

exception to the hearsay rule. For example, when an

appropriate foundation has been laid, autopsy reports have

sometimes been admitted as business records (Evid. Code,

§ 1271; see People v. Beeler (1995) 9 Cal.4th 953, 979 (Beeler)) or

official records (Evid. Code, § 1280; see People v. Clark (1992) 3

Cal.4th 41, 158–159). However, it is significant that the

prosecution did not offer the report itself into evidence, and the

trial court did not rule on whether it was admissible under

either exception. “The proponent of hearsay has to alert the

court to the exception relied upon and has the burden of laying

the proper foundation.” (People v. Livaditis (1992) 2 Cal.4th

759, 778.) A trial court’s decision to admit evidence under a

hearsay exception is entitled to great deference on appeal, but

here foundational testimony was neither elicited by the

prosecution nor ruled upon by the court.

Both the business record and official record exceptions

require a showing that the writing “was made at or near the

time of the act, condition, or event” (Evid. Code, §§ 1271,

subd. (b), 1280, subd. (b)); either “in the regular course of a

business” (id., § 1271, subd. (a)) or “by and within the scope of

duty of a public employee” (id., § 1280, subd. (a)); and that

9.) Accordingly, as the Attorney General acknowledges,

defendant’s failure to object did not forfeit his present claims.

(Ibid.)

48

PEOPLE v. TURNER

Opinion of the Court by Corrigan, J.

“sources of information and method and time of preparation

were such as to indicate [the writing’s] trustworthiness” (id.,

§§ 1271, subd. (d), 1280, subd. (c)). Dr. Scheinin described how

autopsy reports are customarily prepared and maintained in the

Los Angeles County Coroner’s Office, but she did not begin

working there until two years after the autopsy in question. She

did not testify that the same procedures were followed before

her arrival, nor did she link her description of the office’s

procedures to the preparation of this particular autopsy report.

The foundational showing here is notably thinner than we have

encountered in upholding rulings to admit other autopsy

reports. For example, in Beeler, supra, 9 Cal.4th at page 979,

the testifying pathologist both explained the office’s autopsy

procedures and attested that these standard procedures were

followed in the autopsy’s performance and documentation. That

testimony was sufficient to support the court’s admission of the

report as a business record. (Ibid.) In contrast, given the record

here, we cannot say with confidence that the fetal autopsy report

would have been admissible as either a business record or a

public record, and the issue was not explored at trial.

We recognize that the prosecution might reasonably have

perceived no need to offer the autopsy report under a hearsay

exception. When defendant’s case was tried in 2007, courts

frequently allowed experts to relate case-specific hearsay under

the rationale that such evidence merely explained the basis of

the expert’s opinion and was not offered for its truth. (See, e.g.,

Montiel, supra, 5 Cal.4th at p. 919, overruled in Sanchez, supra,

63 Cal.4th at p. 686, fn. 13.) Sanchez changed this aspect of the

law. (See Sanchez, at p. 686.) But, while our treatment of

hearsay has changed in light of evolving Supreme Court

jurisprudence (see id. at p. 682), this change does not make it

PEOPLE v. TURNER

Opinion of the Court by Corrigan, J.

appropriate in this case to uphold the admission of hearsay

against a criminal defendant based on an exception that was

never presented to the trial court, for which no effort was made

to lay the necessary foundation, and on which the court never

ruled.

Had the report been offered and admitted under an

exception, the words of the document itself would have

constituted admissible hearsay. Dr. Scheinin’s recitation of the

content of an unadmitted document remains hearsay for which

no exception was established. She was allowed to present

inadmissible hearsay as true and supportive of her opinion.

This was error under California’s hearsay statutes. (See

Sanchez, supra, 63 Cal.4th at p. 686).

ii. Prejudice

State law error in the admission of hearsay requires

reversal of the judgment if “ ‘it is reasonably probable that a

result more favorable to the [defendant] would have been

reached in the absence of the error.’ ” (People v. Watson (1956)

46 Cal.2d 818, 837 (Watson); see People v. Duarte (2000) 24

Cal.4th 603, 618–619.) Given the significance of the hearsay

evidence to the fetal murder charge, and the dearth of other

evidence on the issue, we cannot conclude the error was

harmless. Defendant’s conviction for the fetal murder count

must be reversed.

The prosecution had to prove the fetus was viable at the

time of death. Dr. Scheinin testified that viability is largely a

function of weight and gestational age. At both the time of trial

and in 1989 when Regina Washington was murdered, scientists

generally considered a fetus viable after it had reached a

gestational age of 22 weeks or a weight of 500 grams. To

50

PEOPLE v. TURNER

Opinion of the Court by Corrigan, J.

illustrate her testimony, Dr. Scheinin displayed a chart showing

the week-by-week development of an embryo into a fetus. She

drew the jury’s attention to a dividing line on this chart labeled

“stage of viability.” She explained, “Anything to the left of this

line is considered a pre-viable fetus and anything to the right of

it is considered viable,” noting the dividing line of weight and

age. Having previously quoted from the autopsy report that the

Washington fetus weighed 825 grams and had reached a

gestational age of 27 to 28 weeks, Dr. Scheinin then pointed to

the place on the chart indicated by these statistics. She

observed that, “according to the medical examiner who did the

autopsy, . . . the baby is in this ballpark here, and about in this

ballpark here by weight, so it’s clearly well into the range that’s

defined as viable.” (Italics added.) Finally, she quoted the

report’s statement that the fetus had “no congenital

abnormalities” and concluded “nothing in the report” suggested

the fetus was anything other than healthy. All of Dr. Scheinin’s

statements about the fetus’s ability to survive outside the womb

were expressly tied to the autopsy report, the contents of which

she presented to the jury. This case-specific information was

neither stipulated nor independently proven.

Dr. Scheinin’s testimony was essential in proving

viability. The only other evidence bearing on the subject was

testimony from Washington’s daughter, 11 years old at the time

of the crime, who recalled that her mother was visibly pregnant

and the family believed the gender was female. This evidence

was insufficient to prove viability beyond a reasonable doubt.

Although the Attorney General is correct that no contrary

evidence was presented, it was the prosecution’s burden to prove

every element of the charge. (See Estelle v. McGuire (1991) 502

U.S. 62, 69; see also Melendez-Diaz v. Massachusetts (2009) 557

51

PEOPLE v. TURNER

Opinion of the Court by Corrigan, J.

U.S. 305, 324 [“the Confrontation Clause imposes a burden on

the prosecution to present its witnesses, not on the defendant to

bring those adverse witnesses into court”].)

The Attorney General argues the error was harmless

because, apart from the hearsay, Dr. Scheinin gave her own

opinion about fetal viability. He reasons that even if she had

been precluded from reciting the report’s facts about fetal

weight and gestational age, she still would have been able to

testify to her opinion on the ultimate question. It is true that an

“expert may still rely on hearsay in forming an opinion, and may

tell the jury in general terms that he did so.” (Sanchez, supra,

63 Cal.4th at p. 685.) Dr. Scheinin thus could have told the jury

that she read the autopsy report and relied on it in forming her

opinion. But that is not what happened here. Instead, she

repeatedly recounted case-specific facts from the report and

invited the jury to compare that hearsay to the medically

accepted guidelines for determining viability.

Once the improperly admitted hearsay testimony is

excluded (see People v. Doolin (2009) 45 Cal.4th 390, 448), all

that remains of Dr. Scheinin’s viability testimony is a bare

conclusion that “just looking at the numbers, the age of the baby

would indicate that it was a viable fetus, meaning it has a

chance for life by itself.” The persuasive force of this conclusion

would have been considerably diminished without testimony

about the case-specific facts on which it was based. An expert’s

opinion is only as strong as its factual basis. “The jury is not

required to accept an expert’s opinion. The final resolution of

the facts at issue resides with the jury alone. The jury may

conclude a fact necessary to support the opinion has not been

adequately proven, even though there may be some evidence in

the record tending to establish it. If an essential fact is not

52

PEOPLE v. TURNER

Opinion of the Court by Corrigan, J.

found proven, the jury may reject the opinion as lacking

foundation.” (Sanchez, supra, 63 Cal.4th at p. 675.) A

conclusory opinion, with no articulated factual foundation,

would have been substantially less compelling than the

testimony Dr. Scheinin actually gave. She repeatedly stated the

fetus’s specific weight and gestational age and showed on a

demonstrative exhibit how these attributes placed it “well into”

the medically established viability range.

The case-specific hearsay erroneously admitted here

served two interrelated purposes. First, it provided nearly all

the direct evidence pointing to fetal viability. Second, it

provided the entire factual basis for the expert’s opinion on that

question. The hearsay evidence was relevant to an especially

important issue. On this record, it is reasonably probable the

jury would have reached a different verdict on the fetal murder

count absent the admission of hearsay evidence. (See Watson,

supra, 46 Cal.2d at p. 837.)

We do not agree with defendant, however, that this error

undermines the penalty judgment. Defendant was a convicted

serial killer who preyed on vulnerable women for over a decade.

A jury convicted him of strangling his victims and abandoning

their corpses in degrading conditions. Apart from the fetal

death, the jury found that defendant murdered 10 women. The

jury heard evidence about these murders and defendant’s sexual

assault of Maria M. In the penalty phase, it heard aggravating

evidence about yet another murder and sexual assault.

Although defendant suggests the jury may have considered the

fetus’s murder especially aggravating, that argument is

speculative at best. Moreover, despite the error, the jury was

still entitled to give aggravating weight to the fact that

defendant murdered a visibly pregnant woman. (See Brown v.

53

PEOPLE v. TURNER

Opinion of the Court by Corrigan, J.

Sanders (2006) 546 U.S. 212, 220.) The prosecutor’s closing

argument only mentioned this death in a single sentence. Nor

was there any victim impact evidence concerning the fetus. In

view of the substantial aggravating facts of both the charged and

uncharged crimes, it is not reasonably possible the jury would

have reached a different penalty verdict absent the error. (See

People v. Johnson (2019) 8 Cal.5th 475, 518.) Likewise, any

federal constitutional error in admitting the evidence was

harmless beyond a reasonable doubt as to penalty. (Chapman,

supra, 386 U.S. at p. 24; see Gonzalez, supra, 38 Cal.4th at

pp. 960-961.)

C. Penalty Phase Issues

1. Criminal Threat Evidence

Defendant contends insufficient evidence was admitted to

establish that he made a criminal threat against Deputy

Uyetatsu. Assuming this claim was not forfeited, any error was

harmless.

To establish a criminal threat, the prosecution must prove:

(1) the defendant willfully threatened death or great bodily

injury to another person; (2) the threat was made with the

specific intent that it be taken as a threat, regardless of the

defendant’s intent to carry it out; (3) the threat was “on its face

and under the circumstances in which it [was] made, . . . so

unequivocal, unconditional, immediate, and specific as to convey

to the person threatened, a gravity of purpose and an immediate

prospect of execution”; (4) the threat caused the person

threatened “to be in sustained fear for his or her own safety or

for his or her immediate family’s safety”; and (5) this fear was

reasonable under the circumstances. (§ 422, subd. (a); see

People v. Toledo (2001) 26 Cal.4th 221, 227–228.) Defendant

54

PEOPLE v. TURNER

Opinion of the Court by Corrigan, J.

challenges the evidentiary support for three elements. First,

defendant argues the evidence does not show he specifically

intended to threaten Deputy Uyetatsu. Although he told

another inmate he planned to kill the deputy if he was convicted

of the pending charges, he did not instruct the inmate to report

the threat to her, nor was there evidence to suggest he thought

such a report was likely. Second, defendant asserts the threat

was not sufficiently unconditional and immediate because he

made it while in a locked cell, and he would have even less

ability to carry it out if he were convicted of the capital charges.

Finally, he argues there was no evidence the threat caused

Deputy Uyetatsu to be in a state of sustained fear. When asked

how she felt upon learning of the threat, Uyetatsu said only that

she thought defendant had the ability to carry it out and would

do so if given the opportunity. She did not say she was afraid,

nor did she testify that she wanted to be moved to a different

unit.

First, the claim is not cognizable on appeal because

defendant did not object or move to strike the evidence he now

challenges. (See People v. Livingston (2012) 53 Cal.4th 1145,

1175; People v. Hamilton (2009) 45 Cal.4th 863, 934.) Defendant

couches his argument as a challenge to the sufficiency of

evidence, noting such claims are generally permitted on appeal

without the need for an objection. (See People v. McCullough

(2013) 56 Cal.4th 589, 596.) However, it is significant that “here

the evidence was admitted at the penalty phase of a capital trial

as aggravating evidence, not to support a conviction for that

crime.” (Livingston, at p. 1175.) “Even if defendant need do

nothing at trial to preserve an appellate claim that evidence

supporting his conviction is legally insufficient, a different rule

is appropriate for evidence presented at the penalty phase of a

55

PEOPLE v. TURNER

Opinion of the Court by Corrigan, J.

capital trial. There the ultimate issue is the appropriate

punishment for the capital crime, and evidence on that issue

may include one or more other discrete criminal incidents.

(§ 190.3, factors (b), (c).) If the accused thinks evidence on any

such discrete crime is too insubstantial for jury consideration,

he should be obliged in general terms to object, or to move to

exclude or strike the evidence, on that ground.” (Montiel, supra,

5 Cal.4th at p. 928, fn. 23.)

Even assuming admission of the threat evidence was

error, there is no reasonable possibility it affected the penalty

verdict. (See People v. Collins (2010) 49 Cal.4th 175, 220.) The

threat was only one of five violent crimes admitted under section

190.3, factor (b) and had arguably less impact. The jury heard

evidence in the penalty phase that defendant had murdered

Elandra Bunn, sexually assaulted Carla W., and forcibly

resisted arrest. It was also directed to consider guilt phase

evidence about his attack on Maria M. The threat was certainly

less impactful than defendant’s capital crimes. Defendant was

a proven serial killer who brutally raped and murdered nearly

a dozen known victims, preying on vulnerable women from his

own neighborhood. As the court stated in denying defendant’s

automatic motion for modification of the verdict, “defendant

methodically located unescorted and vulnerable women,

overwhelmed each of them in isolation, and strangled each to

death for his own sexual pleasure.” The aggravating facts here

were overwhelming, and any error relating to the threat

evidence was clearly harmless.

2. Constitutionality of Death Penalty Law

Defendant raises a number of challenges to the

constitutionality of California’s death penalty statute and

56

PEOPLE v. TURNER

Opinion of the Court by Corrigan, J.

instructions. He acknowledges that we have previously rejected

all of these arguments. We decline to reconsider our precedents

as follows:

Section 190.2 adequately narrows the class of offenders

eligible for the death penalty. (People v. Reed (2018) 4 Cal.5th

989, 1018; Winbush, supra, 2 Cal.5th at p. 488.) Section 190.3,

factor (a), allowing aggravation based on the circumstances of

the crime, does not permit arbitrary and capricious sentencing.

(People v. Capers (2019) 7 Cal.5th 989, 1013 (Capers);

Thompson, supra, 1 Cal.5th at p. 1129.) “Choice of penalty is a

normative decision,” not a factual one. (Beck and Cruz, supra, 8

Cal.5th at p. 670.) Accordingly, the death penalty scheme does

not violate the federal Constitution for failing to require:

• written findings (People v. Rhoades (2019) 8 Cal.5th 393, 455

(Rhoades); Winbush, at p. 490);

• unanimous findings as to proof of each aggravating factor or

unadjudicated crime (Capers, at p. 1013);

• findings that aggravating factors (other than section 190.3,

factors (b) and (c)) were proven beyond a reasonable doubt;

• or specific, articulated findings that aggravating factors

outweigh those in mitigation, or that death is the appropriate

penalty (People v. Krebs (2019) 8 Cal.5th 265, 350 (Krebs);

People v. Rangel (2016) 62 Cal.4th 1192, 1235).

These conclusions are not altered by Apprendi v. New Jersey

(2000) 530 U.S. 466, Ring v. Arizona (2002) 536 U.S. 584, or

Hurst v. Florida (2016) 577 U.S. 92. (Capers, at pp. 1013–1014;

People v. Henriquez (2017) 4 Cal.5th 1, 45.) Because sentencing

is “an inherently moral and normative function, and not a

factual one amenable to burden of proof calculations” (Winbush,

at p. 489), the prosecution has no obligation to bear a burden of

57

PEOPLE v. TURNER

Opinion of the Court by Corrigan, J.

proof or persuasion (Capers, at pp. 1014–1015). Nor does the

federal Constitution require an instruction that life is the

presumptive penalty. (Capers, at p. 1016; Beck and Cruz, at

p. 670.)

CALJIC No. 8.88 is not impermissibly vague or otherwise

defective for failing to require a finding that death is the

“appropriate” penalty (People v. Leon (2020) 8 Cal.5th 831, 853;

see Beck and Cruz, supra, 8 Cal.5th at p. 671) or failing to

require a life sentence if the jury finds that mitigating factors

outweigh aggravating ones (Capers, supra, 7 Cal.5th at p. 1016;

People v. Johnson (2018) 6 Cal.5th 541, 594 (Johnson)). The

phrase “so substantial” in this instruction is not overbroad or

unconstitutionally vague. (Beck and Cruz, at p. 671; People v.

Ghobrial (2018) 5 Cal.5th 250, 292.) Nor is the jury’s

consideration of mitigating factors impermissibly constrained

by CALJIC No. 8.85’s use of the words “extreme” and

“substantial” to describe mitigating circumstances. (Beck and

Cruz, at p. 671; People v. Rices (2017) 4 Cal.5th 49, 94.) The

court is not constitutionally obligated to delete inapplicable

sentencing factors, identify which factors are aggravating or

mitigating, or instruct that certain factors are relevant only for

mitigation purposes. (Krebs, supra, 8 Cal.5th at p. 351;

Rhoades, supra, 8 Cal.5th at p. 455; Winbush, supra, 2 Cal.5th

at p. 490.)

Intercase proportionality review is not constitutionally

required. (Rhoades, supra, 8 Cal.5th at pp. 455–456; Johnson,

supra, 6 Cal.5th at p. 594.) Nor does the death penalty law

violate equal protection by providing different procedures to

capital and noncapital defendants. (Rhoades, at p. 456; Capers,

supra, 7 Cal.5th at p. 1017.) We continue to hold that

California’s capital sentencing scheme does not violate

58

PEOPLE v. TURNER

Opinion of the Court by Corrigan, J.

international norms or evolving standards of decency in

violation of the Eighth and Fourteenth Amendments. (Beck and

Cruz, supra, 8 Cal.5th at p. 671; Krebs, supra, 8 Cal.5th at

p. 351; Capers, at p. 1017.)

D. Cumulative Error

Finally, defendant argues errors in his trial were

cumulatively prejudicial. We conclude to the contrary. (See

People v. Penunuri (2018) 5 Cal.5th 126, 172.) Hearsay was

improperly admitted on the question of fetal viability. That

murder conviction is reversed. We also assumed a penalty

phase error involving evidence that defendant threatened

Deputy Uyetatsu. In light of the totality of evidence at both

phases of trial, reversal of neither the guilt nor penalty

judgments is required for the reasons discussed above.

III. DISPOSITION

The second degree fetal murder conviction is reversed. In

all other respects, the judgment is affirmed.
