MEMORANDUM AND ORDER

ROSENSTENGEL, District Judge:
This case arises out of a series of allegedly illegal stops made by officers of the
municipalities of Williamson County, Illinois, and the City of Marion, Illinois. Plaintiffs
Michael Phelps and Kaleigh Wilkerson (collectively, “Plaintiffs”) originally filed their
Complaint in state court. (Doc. 1-1). Defendants Jeff Diederich, Darren Ferrell, Dustin
Kelly, Krashawn Knight, and Williamson County (collectively, the “Williamson County
Defendants”) removed to this Court (Doc. 1) and filed a Motion to Dismiss (Doc. 6).
Defendants Alex Jiminez, Nicholas Keltner, Jairiah Roberts, Jesse Thompson, and City of
Marion (collectively, the “Marion Defendants”) also filed a Motion to Dismiss. (Doc. 21).
Plaintiffs responded to both motions. (Docs. 9, 27). For the following reasons, the motions
to dismiss are granted in part and denied in part.
BACKGROUND
According to the complaint—the allegations in which are taken as true for
purposes of the motion to dismiss—on July 10, 2024, Plaintiffs were driving through

Marion, Illinois, toward Colorado when they were stopped twice by Defendants. (Doc. 1-
1, ¶¶ 16–31).
The first stop happened that morning as Wilkerson drove. Wilkerson was pulled
over by Defendants Alex Jiminez and Jairiah Roberts, police officers for the City of
Marion. Id. ¶ 18. They told Wilkerson that she had been pulled over for tailgating and

changing lanes without her signal. Id. This was untrue, and the officers knew it; they just
wanted to detain Plaintiffs long enough for a drug-sniffing dog to arrive. See id. ¶ 19.
(The charges filed against Wilkerson based on this stop were ultimately dropped.
Id. ¶¶ 21–22.) Jiminez and Roberts detained Plaintiffs for roughly 40 minutes, but the
drug dog apparently never arrived. See id. ¶ 20. They then allowed Plaintiffs to leave

(though not without giving Wilkerson two tickets). Id. ¶ 20. Phelps switched to the
driver’s seat, and Plaintiffs continued on their way. Id. ¶ 24–26.
But before they let Plaintiffs leave, Jiminez and Roberts reached out to their fellow
defendants: Marion police officers Nicholas Keltner and Jesse Thompson;1 Williamson
County Sheriff Jeff Diederich;2 and Williamson County Sheriff’s Office employees

Krashawn Knight, Darren Ferrell, and Dustin Kelly.3 See id. ¶ 23. Together, they agreed

1 (Doc. 1-1, ¶¶ 9–10).
2 (Doc. 1-1, ¶ 8).
3 (Doc. 1-1, ¶¶ 13–15).
to keep Plaintiffs under surveillance. Id. That way, Defendants could pull Plaintiffs over
again—and this time, they would bring the drug-sniffing dog. Id.

At the second stop, a minimum of five police vehicles4 surrounded Plaintiffs’ car.
Id. ¶ 26. Thompson told Phelps they were being stopped for running a red light. Id. ¶ 28.
(Phelps had not, in fact, run a red light, and Thompson knew it. Id. ¶¶ 28–29.) Knight,
meanwhile, directed a canine around the vehicle, and the canine signaled to the
passenger-side door. Id. ¶ 27. The officers then searched the entire vehicle, including the
locked glove compartment. Id. All told, the officers recovered $3,800 and a gun purchased

in the State of Utah. Id. Plaintiffs were then arrested and forced to spend three days in the
Williamson County jail. Id. ¶ 31. They were charged with two felony offenses, but the
charges were later dropped. Id. ¶¶ 31–32.
The complaint advances a total of 11 counts under both federal and state law.
Wilkerson asserts claims of illegal seizure under the Fourth Amendment5 and false arrest

under Illinois common law against Jiminez and Roberts (Counts I and IV) and all
individual defendants (Counts II and V). Phelps asserts claims of illegal seizure under
the Fourth Amendment and false arrest under Illinois common law against all individual
defendants (Counts VI and VIII). Plaintiffs each assert a claim of illegal search under the

4 Plaintiffs do not identify which officers were driving these vehicles or present at this stop beyond Knight
and Thompson. (See Doc. 1-1, ¶¶ 26–31).
5 In the complaint, Counts I, II, and VI are titled “False Arrest,” but purport to be brought under 42 U.S.C.
§ 1983 and challenge the arrests as having violated the Fourteenth Amendment. (Doc. 1-1, ¶¶ 35–48, 69–
75). The Court construes these counts as alleging an illegal arrest (rather than a “false arrest”) under the
Fourth Amendment (as incorporated by the Fourteenth Amendment). It does so because § 1983 does not
provide a cause of action for state law false arrest claims, e.g., Doe v. Bd. of Trs. of Univ. of Ill., 429 F. Supp. 2d
930, 944 (N.D. Ill. 2006), and because state law false arrest claims are already covered by Counts V and VIII
(Doc. 1-1, ¶¶ 63–68, 84–89).
Fourth Amendment against all individual defendants (Counts III and VII). They assert
Monell claims against the City of Marion (Count IX) and Williamson County (Count X).

And finally, Phelps asserts a claim of conversion against the City of Marion (Count XI).
The Williamson County Defendants filed a motion to dismiss, challenging only
Counts II, III, V-VIII, and X. (Doc. 6). Plaintiffs filed a response, asking the Court to deny
the motion or, to the extent that the motion was meritorious, grant them leave to amend
their complaint. (Doc. 9, at 7–8). The Williamson County Defendants did not file a reply.
By contrast, the Marion Defendants’ motion to dismiss is addressed to all counts

in the complaint. (See Doc. 21). They ask the Court to dismiss Counts I–X and to remand
Count XI. Id. at 3. To support this request, however, the Marion Defendants merely
“adopt the factual . . . and legal argument[s]” set forth by the Williamson County
Defendants. Id. at 2. In other words, the Marion Defendants’ motion simply incorporates
the Williamson County Defendants’ motion by reference.6 They make only one

6 The Marion Defendants’ decision to rely almost exclusively upon the legal arguments of the Williamson
County Defendants has two consequences. First, the Williamson County Defendants did not challenge
Counts I or IV, each of which applies only to Marion police officers Jiminez and Roberts. By relying solely
on the Williamson County Defendants’ arguments, the Marion Defendants have waived their challenge to
Counts I and IV. E.g., Schaefer v. Universal Scaffolding & Equip., LLC, 839 F.3d 599, 607 (7th Cir. 2016)
(“Perfunctory and undeveloped arguments are waived, as are arguments unsupported by legal authority.”
(citing United States v. Hook, 471 F.3d 766, 775 (7th Cir. 2006))). Their motion is accordingly denied as to
those counts.
Second, much of the legal analysis in the Williamson County Defendants’ motion is centered on the
Williamson County Defendants. The Marion Defendants fail to articulate how this analysis should apply
to them. Specifically, the Williamson County Defendants argue that the Monell claim against Williamson
County fails for three reasons: (1) because Plaintiffs failed to articulate a constitutional violation committed
by a Williamson County officer (Doc. 6, at 6); (2) because Plaintiffs failed to allege sufficient facts under
Monell, id. at 7; and (3) because Sheriff Diederich’s conduct as Sheriff cannot be the basis for the County’s
vicarious liability, id. at 7–8. The third reason is plainly inapplicable as to Marion; no Marion sheriff is a
party to this suit. And the first reason does not apply where the Marion Defendants have failed to challenge
Count I, which alleges a constitutional violation by Jiminez and Roberts. Only the second reason—an
argument that Plaintiffs failed to plead a policy or custom—is applicable to Marion.
independent assertion: that the “factual basis” for the Monell claim against the City of
Marion (Count IX7) “is weaker than the [factual basis for the] remaining Counts.” Id. at 3.

Plaintiffs’ response to the motion incorporates by reference their prior response to the
Williamson County Defendants. (Doc. 27). The Marion Defendants did not file a reply.
DISCUSSION
A motion to dismiss under Rule 12(b)(6) “tests whether the complaint states a
claim on which relief may be granted.” Richards v. Mitcheff, 696 F.3d 635, 637
(7th Cir. 2012). The Court accepts as true the complaint’s well-pleaded factual allegations

and draws all reasonable inferences in the plaintiff’s favor. Burke v. 401 N. Wabash Venture,
LLC, 714 F.3d 501, 504 (7th Cir. 2013). To survive a Rule 12(b)(6) motion, a plaintiff only
needs to allege enough facts to state a claim for relief that is plausible on its face. Bell
Atlantic Corp. v. Twombly, 550 U.S. 544, 570 (2007). A plaintiff need not plead detailed
factual allegations, but must provide “more than labels and conclusions, and a formulaic

recitation of the elements.” Id.
I. Illegal Search and Seizure at the Second Stop: 42 U.S.C. § 1983 (Counts II, III,
VI, and VII)
In Counts II, III, VI, and VII, Plaintiffs allege that each individual defendant is
liable under 42 U.S.C. § 1983 for an unconstitutional search and seizure arising from the

“It is not the district court's job to flesh out every single argument not clearly made.” Williams v. Dieball,
724 F.3d 957, 963 (7th Cir. 2013). Accordingly, to the extent that the Williamson County Defendants’
arguments are not clearly cross-applicable, the Marion Defendants’ failure to articulate those arguments in
their motion constitutes waiver.
7 In their Motion to Dismiss, the Marion Defendants refer to the Monell claim against the City of Marion as
“Count X.” (Doc. 21, at 3). The Court assumes they meant to refer to Count IX, as Count X is brought against
Williamson County. The Court construes their motion accordingly.
second stop. To state a viable § 1983 claim, a plaintiff must allege (1) a deprivation of her
rights under the Constitution or federal law, and (2) that the deprivation was committed

by a defendant acting under color of state law. Buchanan-Moore v. County of Milwaukee,
570 F.3d 824, 827 (7th Cir. 2009). Individual liability under § 1983 further requires
personal involvement in the constitutional wrongdoing; a defendant cannot be held liable
unless he caused or participated in the alleged deprivation. Wolf-Lillie v. Sondquist,
699 F.2d 864, 869 (7th Cir. 1983); Zimmerman v. Tribble, 226 F.3d 568, 574 (7th Cir. 2000)
(affirming dismissal for plaintiff’s failure to allege officials’ personal involvement in the

constitutional wrongdoing).
Defendants challenge these counts as to all individual defendants (except Knight
and Thompson) for failing to allege the required personal involvement.8 (Doc. 6, at 4–6).9
Although each individual defendant is sued under Counts II, III, VI, and VII, only the
actions of Knight and Thompson are identified in the complaint. (See Doc. 1-1, ¶¶ 26–31,

42–56, 69–83). Plaintiffs allege Knight directed a canine inspection of their vehicle, giving
rise to a search. Id. ¶ 27. And they allege Thompson “forced” them to exit their vehicle
and lied about the reason for the stop. Id. ¶¶ 27–29. But the complaint is silent as to the
actions and identities of the other officers at the second stop.10 The motion to dismiss

8 Defendants do not appear to argue that the complaint failed to state a claim as to whether Plaintiffs were
(1) subjected to a constitutional deprivation (2) by a defendant acting under color of state law, focusing
instead on the personal involvement requirement. (Doc. 6, at 4–6).
9 Because the Marion Defendants incorporate the Williamson County Defendants’ arguments nearly
wholesale, see supra note 6, the Court cites only to the Williamson County Defendants’ motion except where
a distinction is necessary.
10 The complaint twice references “Defendants” as a collective noun in its description of the second stop.
(Doc. 1-1, ¶ 27 (stating “Defendants then used this alert as a pretext to search the entire vehicle,” but not
identifying who participated in the search); Doc. 1-1, ¶ 30 (stating “[t]he offered reason for the stop was a
pretext to permit the Defendants to conduct and [sic] illegal search of the Plaintiffs’ vehicle,” but again not
argues that “these allegations do not establish that any . . . Defendants personally
searched the interior of the vehicle, found the handgun, issued any traffic citations, or

arrested Plaintiffs,” thus “undermin[ing] any claim that . . . Defendants were personally
involved the misconduct alleged.” (Doc. 6, at 5).
Plaintiffs’ first counterargument is unavailing. They insist that they did allege
personal involvement by each individual defendant (Doc. 9, at 3, 5) and assert that each
Defendant “participated in the [second] stop, the searches, and the eventual arrest. They
were all there and did their part in these unconstitutional deprivations.” Id. at 5. But the

complaint does not contain any details as to what “part” in the second stop each
Defendant ostensibly played; in fact, it does not even allege they were there.11 The
complaint only describes the presence and actions of Knight and Thompson at the second
stop. This is not enough: “An allegation that someone” participated in an illegal search
and seizure “does not propound a plausible contention that a particular person did

anything wrong. . . . Each defendant is entitled to know what he or she did that is asserted
to be wrongful.” Bank of Am., N.A. v. Knight, 725 F.3d 815, 818 (7th Cir. 2013).

identifying who participated)). It is not clear whether these references are meant to refer only to Thompson
and Knight, who are mentioned by name, or to refer to some larger but indeterminate group of Defendants.
11 Plaintiffs resist this conclusion by pointing to their allegation that “five police vehicles jointly participated
in forcing [them] to stop for the purpose of letting Knight’s canine conduct a sniff search.” (Doc. 9, at 3
(citing Doc. 1-1, ¶ 26)). But this allegation does not specify who was driving the five police vehicles. If the other
officers who participated in the second stop were the other named defendants, the complaint should say
so. See Bank of Am., N.A. v. Knight, 725 F.3d 815, 818 (7th Cir. 2013); cf. Car Carriers, Inc. v. Ford Motor Co.,
745 F.2d 1101, 1107 (7th Cir. 1984) (“[I]t is axiomatic that the complaint may not be amended by the briefs
in opposition to a motion to dismiss.” (citations omitted)), overruled in part by, Schmees v. HC1.COM, Inc., 77
F.4th 483, 488–90 (7th Cir. 2023) (rejecting a blanket prohibition on constructively amending a complaint
through briefing but “wholeheartedly agree[ing]” that the practice is generally inappropriate).
Plaintiffs next argue that each officer is liable under a § 1983 conspiracy theory.12
(Doc. 9, at 4–5). To support conspiracy liability under § 1983, a plaintiff “must allege

‘(1) the individuals reached an agreement to deprive him of his constitutional rights, and
(2) overt acts in furtherance actually deprived him of those rights.’” Pena v. Ortiz,
521 F. Supp. 3d 747, 751 (N.D. Ill. 2021) (quoting Beaman v. Freesmeyer, 776 F.3d 500, 510
(7th Cir. 2015)). Once a conspiracy is formed, a conspirator may be liable for acts
committed by co-conspirators in furtherance of the conspiracy, even if the conspirator
did not personally carry out those acts. Geinosky v. City of Chicago, 675 F.3d at 750.

Here, Plaintiffs allege that the individual defendants all reached an agreement to
surveil them for the purpose of conducting the second pretextual stop. (Doc. 1-1, ¶ 23).
And the allegation that they were unconstitutionally subjected to a search and seizure (an
overt act) is not challenged by Defendants. Drawing all permissible inferences in their
favor, it is possible that Plaintiffs state a claim under this theory as to each individual

defendant.

12 While Plaintiffs do discuss § 1983 conspiracy liability, their brief primarily argues for conspiracy liability
under 42 U.S.C. § 1985(3). (Doc. 9, at 4–5). Contrary to their assertions, Plaintiffs do not state a claim under
§ 1985(3), because they do not allege any “racial, or perhaps otherwise class–based invidiously
discriminatory animus behind the conspirators’ action.” Brokaw v. Mercer County, 235 F.3d 1000, 1024
(7th Cir. 2000) (quoting Griffin v. Breckenridge, 403 U.S. 88, 102 (1971)). But “[a]s long as the complaint
contains a claim that is viable under some theory of liability, it survives a motion pursuant to Rule 12(b)(6)
even if one or more theories it offers in support of the claim are inadequate to the task.” Wightman v.
Wauconda Twp. Highway Dep’t, No. 19-CV-2344, 2021 WL 534668, at *4 (N.D. Ill. Feb. 12, 2021) (citing
Bartholet v. Reishauer A.G. (Zurich), 953 F.2d 1073, 1078 (7th Cir. 1992)). Because Plaintiffs correctly identify
that the facts they allege state a claim for conspiracy, their greater focus on § 1985(3) than on § 1983 is not
fatal to their claim.
There are conceivable counterarguments to Plaintiffs’ assertions. But Defendants
do not raise them. In fact, Defendants do not respond to this theory of liability at all.13

“[F]ailure to respond to an opposing party’s argument implies concession.” Midwest
Generation EME, LLC v. Continuum Chem. Corp., 768 F. Supp. 2d 939, 950 (N.D. Ill. 2010)
(citations omitted); cf. Law v. Medco Rsch., Inc., 113 F.3d 781, 787 (7th Cir. 1997) (“Failure
to contest a point is not necessarily a waiver, but it is a risky tactic, and sometimes fatal.”
(citations omitted)). Accordingly, the Court denies Defendants’ motions as to Counts II,
III, VI, and VII.

II. False Arrest at the Second Stop: Illinois Common Law (Counts V and VIII)
Defendants make a similar argument as to Counts V and VIII (Doc. 6, at 4), which
allege false arrest claims under Illinois common law as to “all individual defendants”
(Doc. 1-1, ¶¶ 63–68, 84–89). As discussed above, Plaintiffs do not allege that any
Defendants besides Knight and Thompson were present for the second stop (Doc. 1-1,
¶¶ 26–31, 63–68, 84–89). Accordingly, Defendants argue the complaint fails to state a

claim as to Diederich, Ferrell, Kelly, Keltner, Jiminez, and Roberts (see Doc. 6, at 4).14
In their response, Plaintiffs do not discuss their common law false arrest claims at
all (see Doc. 9, at 3–5);15 they therefore appear to have conceded the point. See Midwest

13 Plaintiffs raised this argument in their response to the Williamson County Defendants’ motion filed on
September 23, 2025. The Williamson County Defendants did not file a reply. The Marion Defendants’
motion to dismiss was filed on November 14, 2025—almost two months after Plaintiffs first argued they
had stated § 1983 claims under a theory of conspiracy liability. But the Marion Defendants did not address
the theory in their motion, and they did not file a reply.
14 Defendants do not appear to argue that Plaintiffs fail to state a claim as to Knight or Thompson.
15 Moreover, Plaintiffs’ response cannot be read as sub silentio addressing Defendants’ challenge to Counts
V and VIII. First, the structure of their brief undermines any such reading. Plaintiffs begin their discussion
of the claims against the individual defendants with the phrase “[t]o state a claim for relief under 42 U.S.C.
§ 1983.” (Doc. 9, at 3 (emphasis added)). Counts V and VIII do not purport to state a claim under § 1983;
Generation EME, LLC, 768 F. Supp. 2d at 950; see also, e.g., Meeks v. Hronec, No. 25-CV-1137,
2026 WL 452379, at *2 (S.D. Ill. Feb. 18, 2026) (“‘It is not the responsibility of the Court to

research and construct parties’ arguments’ for them.” (quoting Rocklane Co. v. Travelers
Cas. Ins. Co. of Am., No. 17-cv-2158, 2020 WL 1320963, at *4 (S.D. Ind. Jan. 21, 2020))).
Accordingly, Counts V and VIII are dismissed without prejudice as to Diederich, Ferrell,
Kelly, Keltner, Jiminez, and Roberts.
III. Monell Claims Against Williamson County and the City of Marion
(Counts IX and X)
In Counts IX and X, Plaintiffs raise Monell claims against the City of Marion and
Williamson County, respectively, asserting that the unconstitutional searches and
seizures at issue were attributable to municipal policies, practices, and decisions.

To survive a motion to dismiss, a plaintiff pursuing a Monell theory of liability
must typically allege one of the following three types of municipal action: “(1) an express
policy that causes a constitutional deprivation when enforced; (2) a widespread practice
that is so permanent and well-settled that it constitutes a custom or practice; or (3) an
allegation that the constitutional injury was caused by a person with final policymaking
authority.” Thomas v. Neenah Joint Sch. Dist., 74 F.4th 521, 524 (7th Cir. 2023) (quoting

Spiegel v. McClintic, 916 F.3d 611, 617 (7th Cir. 2019)); see also Bohanon v. City of Indianapolis,
46 F.4th 669, 672 (7th Cir. 2022) (explaining that municipalities “cannot be held

instead, they explicitly invoke Illinois common law. Similarly, the penultimate sentence of Plaintiffs’
argument asserts that each individual defendant “did their part in these unconstitutional deprivations.”
Id. at 5 (emphasis added). Unlike Counts II, III, VI, and VII, Counts V and VIII do not assert a constitutional
violation. In other words, Plaintiffs saw their argument as encompassing only their federal claims. The
Court therefore declines to construe Plaintiffs’ brief as having made arguments they did not consider
themselves to be making.
vicariously liable under § 1983 for the constitutional torts of their employees; for the
[municipality] to be liable, a municipal policy or custom must have caused [a plaintiff’s]

constitutional injury” (citing Monell v. Dep’t of Soc. Servs., 436 U.S. 658, 694 (1978))).
A. City of Marion (Count IX)
The Marion Defendants argue (by incorporation)16 that Plaintiffs have failed to
allege sufficient facts to support Monell liability. (Doc. 6, at 6–7). Specifically, they point
to a lack of factual allegations showing (1) a specific policy beyond “‘boilerplate
allegations’”; (2) a pattern of misconduct from which a policy could be inferred; (3) or

“proof of knowledge and tacit approval by policy-making officials.” Id. at 7 (quoting
Sivard v. Pulaski County, 17 F.3d 185, 188 (7th Cir. 1994)) (citing Fletcher v. O’Donnell,
867 F.2d 791, 793–94 (3d Cir. 1989)). Instead, the Marion Defendants claim, Plaintiffs
assert only “[a] single incident . . . unaccompanied by supporting history,” from which a
policy cannot be inferred. Id.

Plaintiffs respond to the Marion Defendants’ motion by simply incorporating their
prior response—a decision that dooms Count IX. To defend Monell liability for
Williamson County, Plaintiffs do not rebut the contention that they failed to sufficiently
allege a policy, practice, or custom. (See Doc. 9, at 5–7). Instead, they rely entirely on the
third Monell prong: that a final policymaker caused their constitutional injury. (Doc. 9,

at 5–7). But the complaint only identifies one final policymaker: Diederich, who is the
sheriff of Williamson County. He is not alleged to be a policymaker (final or otherwise) for

16 As discussed above, only some of the Williamson County Defendants’ argumentation can be cross-
applied to the Marion Defendants. See supra note 6.
the City of Marion. Accordingly, the argument is non-responsive as to Count IX. By failing
to rebut the Marion Defendants’ contention that their allegations were insufficiently

specific for Monell liability, Plaintiffs have waived the argument.
But even if Plaintiffs had not committed waiver, the Marion Defendants have the
better of the argument. The complaint’s allegations against the City of Marion (Doc. 1-1,
¶¶ 90–100) “are actually legal conclusions or elements of the cause of action, which may
be disregarded on a motion to dismiss.” McCauley v. City of Chicago, 671 F.3d 611, 617
(7th Cir. 2011). Plaintiffs do not allege facts showing a municipal policy, widespread

practice, or deliberate indifference by City policymakers. Nor do they allege any prior
instances of similar unconstitutional traffic stops, specific deficiencies in training
programs, or any facts suggesting that City of Marion policymakers were on notice of a
pattern of unconstitutional conduct and failed to act. Instead, their claim rests solely on
the events of the traffic stop at issue and conclusory legal assertions of municipal failure.

Because such allegations are insufficient to state a claim, Count IX would be dismissed
even absent Plaintiffs’ waiver.
B. Williamson County (Count X)
The Williamson County Defendants argue Count X should be dismissed for two
principal reasons: (1) the factual allegations are insufficient under any prong of Monell
(Doc. 6, at 7); and (2) Sheriff Diederich’s conduct as Sheriff cannot be the basis for the

County’s vicarious liability, id. at 7–8.17 Plaintiffs’ response is to rely on Diederich’s status

17 As previously discussed, supra note 6, the Williamson County Defendants also challenge Count X on a
third ground: that Plaintiffs do not articulate an underlying constitutional violation committed by a
as Sheriff of Williamson County. (Doc. 9, at 5–7). They point to the Williamson County
Defendants’ acknowledgment that the county sheriff is “an independently elected

constitutional officer” who “operates with a significant degree of autonomy from the
county” (Doc. 6, at 8), arguing it is essentially an admission that he has “final
policymaking authority” sufficient for Monell liability to attach.
But Plaintiffs misapprehend Illinois law. “[I]n Illinois, a county sheriff is an
‘independently elected county officer and is not an employee of the county in which the
sheriff serves.’ Although Illinois sheriffs may be agents of their county, they are not

subject to their county’s control. As such, [c]ourts routinely dismiss Monell claims against
counties that fail to assert any pattern of inaction or lack of enforcement on the part of the
counties themselves and are actually predicated on alleged misconduct by the sheriffs’
offices.” DiMaio v. Wexford Health Sources, Inc., No. 19-cv-06613, 2021 WL 1056848, at *6
(N.D. Ill. Mar. 19, 2021) (quoting Martinez v. Sergeant Hain, No. 16-cv-2237, 2016 WL

7212501, at *4 (N.D. Ill. Dec. 13, 2016)) (citations omitted); see also Franklin v. Zaruba,
150 F.3d 682, 686 (7th Cir. 1998) (explaining that Ҥ 1983 suits against sheriffs in their
official capacities are in reality suits against the county sheriff’s department rather than
the county board”). In other words, Williamson County cannot be liable under Monell for
the actions of Diederich as policymaker, as he holds that role only with respect to the

Williamson County Sheriff’s Office.

Williamson County officer. (Doc. 6, at 6). But because Plaintiffs do state a constitutional claim in Counts II,
III, VI, and VII, this third ground is unavailing.
So Monell liability lies, if at all, with Sheriff Diederich in his official capacity, not his
individual capacity. Cf, e.g., DiMaio, 2021 WL 1056848, at *2–5 (evaluating Monell claim

against an Illinois sheriff in his official capacity separately from both a claim against him
in his individual capacity and a Monell claim against the county). But Plaintiffs sued
Diederich only in his individual capacity and concede as much in their response. (Doc. 1-
1, ¶ 8; see Doc. 9, at 7 (expressing an intent to “seek leave to bring suit against the Sheriff
in his official capacity as well”)).
Count X cannot lie against Williamson County, and the only defendant against

whom it could lie (Diederich in his official capacity) is—by Plaintiffs’ concession—not
named here. Accordingly, Count X is dismissed.18
IV. Leave to Amend
At the close of their brief, Plaintiffs make a request: “If this Court ultimately
concludes that any part of the Rule 12(b)(6) Motion has merit, Plaintiffs request that they
be given the opportunity to plead in more detail as they do contend that there is more

than a plausible claim against each one of these Defendants.” (Doc. 9, at 8). The Court
construes this as a request for leave to amend their complaint.
Rule 15(a)(2) provides that courts “should freely give leave when justice so
requires.” FED. R. CIV. P. 15(a)(2). Though all Defendants had an opportunity to oppose
amendment in a reply or response brief, none have done so. Accordingly, the Court

grants Plaintiffs leave to amend. See Zimmerman v. Bornick, 25 F.4th 491, 494 (7th Cir. 2022)

18 However, Williamson County is an indispensable party to this action under Carver v. Sheriff of LaSalle
County, 324 F.3d 947 (7th Cir. 2000), as acknowledged by both Defendants and Plaintiffs (Doc. 6, at 8; Doc. 9,
at 7). Williamson County, therefore, will not be dismissed from this action despite the dismissal of Count X.
(“[T]he norm remains affording a plaintiff at least one opportunity to amend his
complaint.” (first citing Loja v. Main St. Acquisition Corp., 906 F.3d 680, 685 (7th Cir. 2018);
and then citing Glover v. Carr, 949 F.3d 364, 367-69 (7th Cir. 2020))).
CONCLUSION
For these reasons, the Motion to Dismiss filed by the Williamson County
Defendants (Doc. 6) is GRANTED in part and DENIED in part. Counts V and VIII are
DISMISSED without prejudice as to Defendants Diederich, Ferrell, and Kelly, and
Count X is DISMISSED without prejudice. The Motion to Dismiss filed by the Marion
Defendants (Doc. 21) is GRANTED in part and DENIED in part. Counts V and VIII are
DISMISSED without prejudice as to Defendants Keltner, Jiminez, and Roberts, and
Count IX is DISMISSED without prejudice.
Further, the Court GRANTS Plaintiffs Phelps and Wilkerson’s request for leave to
amend their complaint. Any amended complaint must be filed on or before May 26, 2026.
IT IS SO ORDERED.
