Appellant : No. 554 EDA 2019
Appeal from the Judgment of Sentence Entered October 19, 2018
In the Court of Common Pleas of Philadelphia County Criminal Division at
No(s): CP-51-CR-0008231-2017
BEFORE: SHOGAN, J., KUNSELMAN, J., and COLINS, J.*
MEMORANDUM BY COLINS, J.: April 1, 2020
Appellant, Aaron S. Mattox, appeals from the aggregate judgment of
sentence of six to fifteen years of confinement, which was imposed after his
jury trial convictions for: three counts each of knowingly and intentionally
making any materially false statement in connection with the purchase,
delivery, or transfer of a firearm and conspiracy to commit said crimes; and
one count of possession of firearm prohibited.1 We affirm.
In its opinion, the trial court fully and correctly set forth the relevant
facts and procedural history of this case. See Trial Court Opinion (“Tr. Ct.

Opinion”), dated May 29, 2019, at 1-6. Therefore, we have no reason to
restate them at length here.
For the convenience of the reader, we briefly note that Agent
Martin Dietz, a member of Pennsylvania’s Gun Violence Task Force, with
“nearly 12 years of experience” with the task force, was working undercover
at the Oaks Gun Show on August 7, 2016, when he witnessed Appellant and
Sheila White approach a gun dealer’s table and examine Glock pistols, then
saw White purchase two of them. Tr. Ct. Opinion, dated May 29, 2019, at 3,
5, 16 (citing N.T., 8/1/2018, at 67, 74-76, 79, 85-87, 100).2 During the
transaction, Agent Dietz took a photograph of Appellant holding a firearm. Id.
at 16 (citing Exhibit C-2H; N.T., 8/1/2018, at 82). Those purchases turned
out to be “straw purchases” for a third party, Wayne Clanton. See, e.g., id.
at 2-3, 5-6 (citing N.T., 8/1/2018, at 127-28, 173-74, 197-99, 206-07, 219-
21; N.T., 8/2/2018, at 41-42, 70-75).
Agent Dietz testified at Appellant’s trial but was not qualified as an
expert. During Agent Dietz’s testimony, the Commonwealth presented the

She pleaded to three counts each of knowingly and intentionally making any
materially false statement in connection with the purchase, delivery, or
transfer of a firearm, 18 Pa.C.S. § 6111(g)(4), conspiracy to commit said
crimes, id. § 903, conspiracy to commit possession of firearm prohibited, id.,

aforementioned photograph as an exhibit and asked Agent Dietz to describe
it. Id. at 16 (citing Exhibit C-2H; N.T., 8/1/2018, at 82).
In response, Agent Dietz testified that it was a picture of
[Appellant] holding a firearm, to which [defense] counsel did not
object. [N.T., 8/1/2018, at 82.] On cross-examination, defense
counsel asked whether it is “possible that the item [Appellant] is
holding is not a handgun” and, instead, an antique. [Id.] at 150.
Agent Dietz said it was possible. Id. On redirect examination,
the Commonwealth asked Agent Dietz whether he thought the
item in [Appellant]’s hand in the picture was an antique or a
working firearm. [Id.] at 160. Over defense counsel’s objection,
Agent Dietz testified that he observed [Appellant] holding the gun
at the show “[b]ased on [his] experience and [his] observations
at the gun show and simply on this photograph, this is a real gun.
It’s not a replica.” [Id.] at 160-61. . . . Agent Dietz . . . testified
that he believed the gun was real based on its location among
numerous other firearms in the photo, which were sitting on a
table, and were displayed by the gun dealer. [Id.] at . . . 161.
Further, Agent Dietz testified that “the simulated firearms that [he
has] seen at the gun shows, for the most part, have a red or
international orange tip on the end, for the most part.” [Id.] The
gun that [Appellant] was holding in the picture did not have a red
or international orange top on the end.
Id. at 16-17.
On August 3, 2018, a jury convicted Appellant of the aforementioned
counts, and he was sentenced on October 19, 2018. Appellant filed a post-
sentence motion, which was denied on February 5, 2019. Appellant filed this
timely direct appeal on February 19, 2019.3
In his appellate brief, Appellant presents the following issues for our
review:
____________________________________________
3Appellant filed his statement of errors complained of on appeal on March 18,
2019. The trial court entered its opinion on May 29, 2019.
-3-
J-S69040-19
I. Was the evidence insufficient to sustain [Appellant]’s
convictions since the Commonwealth’s evidence was so fraught
with inconsistencies between the testimony of Sheila White, Agent
Martin Dietz and Agent Joseph Ruta [of the Bureau of Alcohol,
Tobacco, Firearms and Explosives] and their prior statements
and/or reports, that a verdict based upon it was inherently
unreliable and could amount to no more than surmise or
conjecture?
II. Did the [trial] court err in finding that it possessed venue
over the purchase and sale of firearms that occurred in
Montgomery County?
III. Did the [trial] court err in permitting Agent Martin Dietz to
speculate as to whether a gun [Appellant] was depicted holding
was a working firearm?
Appellant’s Brief at 3 (trial court’s answers omitted). These challenges,
including their exact language, are identical to those raised in Appellant’s
statement of errors complained of on appeal pursuant to Pa.R.A.P. 1925(b).
Preliminarily, we note --
When challenging the sufficiency of the evidence on appeal, the
appellant’s Pa.R.A.P. 1925 statement must specify the element or
elements upon which the evidence was insufficient in order to
preserve the issue for appeal. Such specificity is of particular
importance in cases where, as here, the appellant was convicted
of multiple crimes each of which contains numerous elements that
the Commonwealth must prove beyond a reasonable doubt.
Commonwealth v. Hoffman, 198 A.3d 1112, 1125 (Pa. Super. 2018)
(citation and internal brackets omitted). In the current action, Appellant not
only failed to specify which elements he was challenging in his statement of
errors, he also failed to specify which convictions he was challenging. While
the trial court did address the topic of sufficiency in its opinion, “we have held
that this is of no moment to our analysis because we apply Pa.R.A.P. 1925(b)
in a predictable, uniform fashion, not in a selective manner dependent on an
-4-
J-S69040-19
appellee’s argument or a trial court’s choice to address an unpreserved claim.”
Commonwealth v. Gibbs, 981 A.2d 274, 281 (Pa. Super. 2009) (citation
and internal quotation marks omitted). Accordingly, we deem Appellant’s first
issue waived.4
Additionally, Appellant never challenged venue before the trial court nor
requested a change of venue before or during trial,5 and his second claim
consequently is also waived. Pa.R.A.P. 302(a) (“Issues not raised in the lower
court are waived and cannot be raised for the first time on appeal.”).
____________________________________________
4 Assuming this claim were not waived, we would still observe that Appellant
has conflated sufficiency of the evidence and weight of the evidence. Weight
of the evidence and sufficiency of the evidence are not the same concepts and
are not interchangeable. See Commonwealth v. Widmer, 744 A.2d 745,
751 (Pa. 2000) (delineating the distinctions between a claim challenging the
sufficiency of the evidence and a claim that challenges the weight of the
evidence). Appellant contends that “the Commonwealth’s evidence was . . .
fraught with inconsistencies” or “riddled with inconsistencies” and “was
inherently unreliable” and that White “directly contradicted” Agent Dietz’s
testimony. Appellant’s Brief at 14-15 (citing N.T., 8/1/2018, at 90; N.T.,
8/2/2018, at 15-16). Allegations of conflicting or contradictory testimony and
questions of credibility are challenges to the weight of the evidence, not to the
sufficiency. See Commonwealth v. Knox, 219 A.3d 186, 198 (Pa. Super.
2019) (weight claim based on conflict in testimony); Commonwealth v.
Roane, 204 A.3d 998, 1001 (Pa. Super. 2019) (“weight of the evidence is
exclusively for the finder of fact, who is free . . . to determine the credibility
of the witnesses”; “[t]he fact-finder also has the responsibility of resolving
contradictory testimony”).
5 Prior to trial, defense counsel asked the trial court, “[H]ow does this Court
have jurisdiction over crimes that occurred in Montgomery County?” N.T.,
8/1/2018, at 14. Jurisdiction and venue are distinct, and a challenge to one
does not encompass a challenge to the other. See Commonwealth v.
Bethea, 828 A.2d 1066, 1074-75 (Pa. 2003) (“jurisdiction references the
power of a court to entertain and adjudicate a matter while venue pertains to
the locality most convenient to the proper disposition of a matter”).
-5-
J-S69040-19
Finally, Appellant contends that the trial court erred “in permitting Agent
Martin Dietz to speculate as to whether a gun [Appellant] was depicted holding
was a working firearm.” Appellant’s Brief at 17. He argues that “Agent Dietz
was not offered by the Commonwealth as an expert witness in the field of
firearms operability and identification nor did he submit an expert report[,]”
and, ergo, the trial court should not have “permitted Dietz to opine that the
gun . . . was a working operable firearm.” Id. at 18 (citing N.T., 8/1/2018,
at 160).
The admissibility of evidence is a matter within the sound
discretion of the trial court and will be reversed only where there
is a clear abuse of discretion. . . . Evidence is admissible if it is
relevant—that is, if it tends to establish a material fact, makes a
fact at issue more or less probable, or supports a reasonable
inference supporting a material fact—and its probative value
outweighs the likelihood of unfair prejudice.
Commonwealth v. Clemons, 200 A.3d 441, 474 (Pa. 2019) (citations
omitted).
Pennsylvania Rule of Evidence 701 controls opinion testimony by lay
witnesses:
If a witness is not testifying as an expert, testimony in the form
of an opinion is limited to one that is:
(a) rationally based on the witness’s perception;
(b) helpful to clearly understanding the witness’s testimony
or to determining a fact in issue; and
(c) not based on scientific, technical, or other specialized
knowledge within the scope of Rule 702.
Pennsylvania Rule of Evidence 702 controls testimony by expert witnesses:
-6-
J-S69040-19
A witness who is qualified as an expert by knowledge, skill,
experience, training, or education may testify in the form of an
opinion or otherwise if:
(a) the expert’s scientific, technical, or other specialized
knowledge is beyond that possessed by the average
layperson;
(b) the expert’s scientific, technical, or other specialized
knowledge will help the trier of fact to understand the
evidence or to determine a fact in issue; and
(c) the expert’s methodology is generally accepted in the
relevant field.
This Court has further distinguished expert testimony and lay testimony as
follows:
[E]xpert testimony “reflects the application of expertise” and does
not “stray[ ] into matters of common knowledge.” Nobles v.
Staples, Inc., 150 A.3d 110, 114 (Pa. Super. 2016) (citation
omitted). We have further explained that expert testimony
“requires knowledge, information or skill beyond what is
possessed by the ordinary juror,” Ovitsky v. Capital City Econ.
Dev. Corp., 846 A.2d 124, 126 (Pa. Super. 2004) (quoting
Commonwealth v. Carter, 403 Pa.Super. 615, 589 A.2d 1133,
1134 (1991)), and that expert testimony must be “distinctly
related to a science, skill or occupation which is beyond the
knowledge or experience of an average lay person” and does not
“involve[ ] a matter of common knowledge.” Commonwealth v.
Minerd, 562 Pa. 46, 753 A.2d 225, 230 (2000).
Commonwealth v. Manivannan, 186 A.3d 472, 485 (Pa. Super. 2018),
reargument denied (July 7, 2018); see also Commonwealth v. Griffith, 32
A.3d 1231, 1239 (Pa. 2011) (“Pursuant to our general standard, a need for
expert testimony arises when the jury is confronted with factual issues whose
resolution requires knowledge beyond the ken of the ordinary layman.”
(emphasis added) (citation and internal quotation marks omitted)).

J-S69040-19
In the current action, Agent Dietz gave two reasons why he thought that
the object held by Appellant in Exhibit C-2H was a firearm. First, “he believed
the gun was real based on its location among numerous other firearms in the
photo, which were sitting on a table, and were displayed by the gun dealer.”
Tr. Ct. Opinion, dated May 29, 2019, at 16 (citing N.T., 8/1/2018, at 161).
This statement was rationally based on Agent Dietz’s perception and did not
require scientific, technical, or other specialized knowledge beyond that
possessed by the average layperson. Pa.R.E. 701-702. Hence, this assertion
was appropriate for Agent Dietz to make as a lay witness, and he thereby did
not have to be certified as an expert to make this declaration. Id.
The second reason that Agent Dietz gave for concluding that the item
held by Appellant in Exhibit C-2H was a real firearm and not a replica was that
“the stimulated firearms that [he has] seen at the gun shows, for the most
part, have a red or international orange tip at the end[.]” Tr. Ct. Opinion,
dated May 29, 2019, at 16 (citing N.T., 8/1/2018, at 161). This reason in
support of Agent Dietz’s opinion required his specialized knowledge,
experience, training, and education from his “nearly 12 years of experience in
the Gun Violence Task Force,” and is not common knowledge. Pa.R.E. 702;
Tr. Ct. Opinion, dated May 29, 2019, at 16 (citing N.T., 8/1/2018, at 67);
Manivannan, 186 A.3d at 485. Thus, Agent Dietz should not have been
permitted to give this explanation without having been qualified as an expert
witness. Pa.R.E. 702; Manivannan, 186 A.3d at 485.
-8-
J-S69040-19
However, this error was harmless. Harmless error in the admission of
evidence can be found where “the error did not prejudice the defendant or the
prejudice was de minimis[.]” Commonwealth v. Jacoby, 170 A.3d 1065,
1085 (Pa. 2017). Appellant could not have been prejudiced by Agent Dietz’s
second explanation, because the agent’s opinion was not based solely upon
the fact that the firearm held by Appellant in the photograph did not have a
red or orange tip but, as explained above, also upon the location of that
firearm near other real handguns displayed by a gun dealer. Tr. Ct. Opinion,
dated May 29, 2019, at 16 (citing N.T., 8/1/2018, at 161). Furthermore,
Exhibit C-2H was published to the jury, and the jurors thus could rely upon
their own individual observations of the photograph, see that the firearm in
question was located among many other firearms that were displayed by a
gun dealer, and determine for themselves whether they believed that the item
held by Appellant was a real firearm. Therefore, even if Agent Dietz had never
given his opinion as to whether the item was a working firearm, a jury still
likely would have concluded that it was a functioning handgun just by looking
at the photograph. For these reasons, Appellant did not suffer any prejudice
from Agent Dietz’s testimony, and, to the extent that any of it was erroneously
admitted, said error was harmless. See Jacoby, 170 A.3d at 1085.
Based on the foregoing, Appellant is not entitled to relief. We thereby
affirm the judgment of sentence.
Judgment of sentence affirmed.
