Before S CUDDER , PRYOR , and K OLAR , Circuit Judges.
S CUDDER , Circuit Judge. Bernard Mims served ten years in
prison for a murder an Illinois court later determined he did
not commit. Mims then invoked 42 U.S.C. § 1983 and sued the
City of Chicago and members of its police department, alleg-
ing, among other claims, that two detectives violated his due
process rights under Brady v. Maryland, 373 U.S. 83 (1963), by
concealing an exculpatory audio recording from the prosecu-
tion in his criminal trial. The district court determined that

Mims failed to show the detectives concealed or otherwise
withheld the recording from the prosecutor. We agree and af-
firm.

A
On October 12, 2000, Dwayne Baker was working as a se-
curity guard at the Rosenwald, a public housing building on
East 47th Street in Chicago. Shortly after midnight, a gold
SUV pulled up to the gas station across the street from the
building’s front entrance. Two individuals then exited the
SUV, and one began firing an AK-47 in the direction of the
Rosenwald. The shooter killed Baker and injured another by-
stander.
Chicago Police Department Detective Daniel McNally be-
gan his work on the homicide investigation later that day. In
short order, CPD came to believe the shooting was gang re-
lated, part of an ongoing feud between the Black Disciples
and the Gangster Disciples. Early indications suggested that
the shooter had mistaken Baker for a member of the Gangster
Disciples.
In February 2001, Detective McNally interviewed Melvin
Richardson, a member of the Black Disciples, who denied in-
volvement in the Baker murder. In the course of the interview,
however, Richardson described a conversation he had a few
months earlier with Michael Sardin, a fellow Black Disciples
member. By Richardson’s telling, Sardin stated that he and
two other Black Disciples, Taboo McNeal and Dwayne Ches-
ter, drove a truck to the Rosenwald to shoot rivals and, more
specifically, that Chester fired shots at the building. Based on
this information, Detective McNally sought to use Richardson

more proactively in the ongoing investigation of the Baker
murder. He did so by seeking court approval to authorize
Richardson to transmit his future conversations for law en-
forcement to record—essentially to wear a wire—a form of
authorization the parties refer to as a “confidential overhear.”
Detective McNally submitted the application to Cook
County Circuit Court Judge Michael Toomin. Earlier in the
year, Judge Toomin had twice before authorized confidential
overhear recordings related to the Baker homicide. The par-
ties refer to those prior authorizations as “COH 003” and
“COH 007,” with “COH” being the shorthand for a confiden-
tial overhear. These details become important.
On February 21, 2001, Judge Toomin authorized the third
confidential overhear, COH 013. His order allowed Detective
McNally, other CPD officers, and various members of the
Cook County State’s Attorney’s Office to record and listen to
conversations between Richardson and Sardin, among others
with suspected involvement in the Baker homicide.
Key to this appeal, the COH 013 recordings generated five
audio files. We focus on one that captured a conversation be-
tween Richardson and Sardin in late February or early March
2001. During their discussion—construed most favorably to
Mims—Sardin confirmed that he previously claimed involve-
ment in the Baker murder. But, for much of their exchange,
Sardin appears to backtrack by denying many times over any
actual involvement in the crime.
Upon listening to the recordings associated with COH 013,
Detective McNally became concerned that Richardson had
tipped off Sardin that their conversations were being taped.
As a result, Detective McNally decided to stop using

-- 3 of 15 --

4 No. 24-1564
Richardson as a confidential informant. Even more, everyone
seems to agree that, from that time forward, Detective
McNally had no further role in the Baker homicide investiga-
tion.
In March 2001, Judge Toomin entered an order stating that
he had listened to all of the COH 013 recordings, as required
by Illinois law. See 725 ILCS 5/108A-7(b). He also ordered the
original recordings “to be impounded and held in the custody
of the Clerk of the Circuit Court under seal.” Judge Toomin
further ordered the Cook County State’s Attorney’s Office to
keep a set of copies.
These early investigative steps did not lead to an immedi-
ate arrest in the Baker homicide. Later in 2001, however,
CPD’s Cold Case Squad took a fresh look at the crime. For his
part, Detective Ted Przepiora conducted interviews and came
to view Bernard Mims as a potential suspect.
But the investigation again went quiet until a series of re-
interviews in 2003 and 2004 reinvigorated interest in Mims.
Around this same time, Assistant State’s Attorney William
Delaney, a prosecutor in the cold case homicide unit within
the Cook County State’s Attorney’s Office, became involved
in the investigation. In July 2004, ASA Delaney helped Detec-
tive Przepiora secure a warrant to arrest Mims for the murder
of Dwayne Baker. Not long after, a Cook County grand jury
indicted Mims on one count of first-degree murder and three
counts of attempted murder.
The case against Mims proceeded before Judge Toomin.
ASA Delaney led the prosecution, and Daniel Franks served
as Mims’s counsel. At multiple pretrial hearings, the parties
discussed the three investigative confidential overhears

-- 4 of 15 --

No. 24-1564 5
(COH 003, COH 007, and COH 013). In the course of discov-
ery, ASA Delaney produced two of the five recordings made
pursuant to COH 013. But neither of those recordings con-
tained the discussion between Melvin Richardson and Mi-
chael Sardin that confirmed Sardin’s prior claim of involve-
ment in the Baker homicide. That particular recording, along
with two others, was not turned over to Franks, and in time
that lack of production would come to form the basis of
Mims’s civil Brady claim.
But the record does show that ASA Delaney provided de-
fense counsel Franks with copies of all affidavits and judicial
orders associated with all three confidential overhear applica-
tions (again, COHs 003, 007, and 013). The COH 013 applica-
tion materials contained express references to the initial con-
versation between Richardson and Sardin that forms the
foundation of Mims’s Brady claim. To date, no actual record-
ings from COH 003 or COH 007 have been located. Nor does
this appeal in any way relate to information believed to be
recorded as part of those two authorizations.
In the end, Mims opted for a bench trial before Judge
Toomin. The trial ended in a conviction for the first-degree
murder of Dwayne Baker and the attempted murder of by-
standers present at the Rosenwald at the time of the shooting.
Judge Toomin sentenced Mims to 95 years’ imprisonment.
In 2015, when Mims was about ten years into his sentence,
the Conviction Integrity Unit of the Cook County State’s At-
torney’s Office took a renewed look at the case against him.
In October 2016, the Office petitioned the Circuit Court of
Cook County to vacate Mims’s conviction and sentence. The
court granted the petition the same day and ordered his im-
mediate release. The Cook County State’s Attorney’s Office

-- 5 of 15 --

6 No. 24-1564
issued an accompanying press statement explaining that a se-
ries of factors—all unrelated to the Brady claim before us on
appeal—led it to lack confidence in Mims’s murder convic-
tion. In November 2016, Mims obtained a Certificate of Inno-
cence from the Circuit Court of Cook County.
B
Mims reacted to these developments by filing this § 1983
action against the City of Chicago and nine CPD detectives.
He alleged wrongful conviction and sought civil damages on
a range of claims under the U.S. Constitution and state law.
Our focus is on the facts pertinent to the only claim before us
on appeal—Mims’s contention that Detectives Daniel
McNally and Ted Przepiora violated his due process rights
under Brady by concealing the recording of a discussion be-
tween Melvin Richardson and Michael Sardin. Mims views
the conversation as exculpatory because it confirms that Sar-
din previously identified someone else as responsible for
shooting and killing Dwayne Baker. For purposes of this ap-
peal, although the recording is far from clear, we accept
Mims’s characterization of its contents.
During discovery in federal court, a Cook County Circuit
Court judge ordered the Clerk of Court to release all im-
pounded and sealed recordings created pursuant to COHs
003, 007, and 013. We glean from the parties’ briefs that what
followed was the production of all five original recordings
made pursuant to COH 013.
Over time the parties have narrowed the defendants and
claims at issue in this case. The district court ultimately en-
tered summary judgment for the City and police detectives
on all four of Mims’s remaining claims: concealment of

-- 6 of 15 --

No. 24-1564 7
evidence in violation of his due process rights under Brady,
fabrication of evidence in violation of his due process rights,
and two state law claims involving the City’s financial re-
sponsibility for the alleged misconduct. Mims has further nar-
rowed our focus on appeal. He challenges only the district
court’s entry of summary judgment on the first claim, which
alleged that Detectives McNally and Przepiora suppressed
the exculpatory recording of Richardson and Sardin in viola-
tion of Brady.
The district court rejected the Brady claim on several
grounds. The district court first acknowledged that Mims’s
trial counsel, Daniel Franks, received only two of five record-
ings made pursuant to COH 013. But it then determined that
Mims failed to identify evidence permitting a jury to find that
Detectives McNally and Przepiora withheld the Richardson-
Sardin recording from the prosecutor. The district court also
concluded that Mims’s claim failed for the independent rea-
son that the Richardson-Sardin conversation was not material
within the meaning of Brady. More specifically, the district
court found that there was no reasonable probability that
Judge Toomin’s verdict would have changed had defense
counsel received the Richardson-Sardin recording in discov-
ery.
Finally, by way of alternative reasoning, the district court
determined that qualified immunity protected Detectives
McNally and Przepiora from § 1983 liability. It found no
clearly established law requiring police officers to ensure that
defense counsel receives court-impounded materials to which
the prosecutor, here Assistant State’s Attorney William
Delaney, had access at all relevant times.
This appeal followed.

We review the district court’s award of summary judg-
ment by taking our own independent look at the facts and the
law, drawing all inferences in favor of Mims as the non-mov-
ing party. See Davis v. Rook, 107 F.4th 777, 780 (7th Cir. 2024).
We will affirm if Mims has not met “his burden to produce
sufficient evidence—not mere speculation—on each essential
element of his [Brady] claim[].” Moran v. Calumet City, 54 F.4th
483, 491 (7th Cir. 2022).
A
In Brady, the Supreme Court translated the Constitution’s
broad guarantee of due process into a practical protection,
holding that “the suppression by the prosecution of evidence
favorable to an accused … violates due process where the ev-
idence is material either to guilt or to punishment, irrespec-
tive of the good faith or bad faith of the prosecution.” 373 U.S.
at 87. Brady’s protection recognizes the “special role played by
the American prosecutor in the search for truth in criminal
trials” by imposing an affirmative duty on prosecutors to
learn of and to disclose to defendants all potentially exculpa-
tory evidence, including evidence known only to police.
Strickler v. Greene, 527 U.S. 263, 281 (1999); see also Anderson v.
City of Rockford, 932 F.3d 494, 504 (7th Cir. 2019) (articulating
the same standard).
The prosecutor’s broad duty of disclosure does not shield
the police from all responsibility under Brady, however. If po-
lice officers conceal exculpatory evidence from the prosecu-
tion, their actions can form the basis of a due process viola-
tion. See Carvajal v. Dominguez, 542 F.3d 561, 566 (7th Cir.
2008). To prevail on a Brady claim against a police officer, a

-- 8 of 15 --

No. 24-1564 9
criminal defendant must show that the non-disclosed evi-
dence was favorable to him, the police officer concealed or
suppressed that evidence, and, finally, that the withheld evi-
dence resulted in prejudice. See Jones v. York, 34 F.4th 550, 559
(7th Cir. 2022).
Under Brady, suppression requires a showing that the
“prosecution failed to disclose evidence that it or law enforce-
ment was aware of before it was too late for the defendant to
make use of the evidence” and “the evidence was not other-
wise available to the defendant through the exercise of rea-
sonable diligence.” Boss v. Pierce, 263 F.3d 734, 740 (7th Cir.
2001). Concealed evidence is prejudicial, and therefore mate-
rial, if there is a reasonable probability that the outcome of a
proceeding would have been different if the evidence had
been disclosed. See Strickler, 527 U.S. at 280.
But the law is equally clear that Brady’s disclosure obliga-
tion rests primarily with the prosecution. See Moran, 54 F.4th
at 492. “[O]ur case law has established that the police gener-
ally discharge their Brady duty by turning over exculpatory
evidence to the prosecutor, thereby triggering the prosecu-
tor’s disclosure obligation.” Beaman v. Freesmeyer, 776 F.3d
500, 512 (7th Cir. 2015). Put another way, a criminal defendant
generally cannot establish a Brady violation by pointing to a
police failure to disclose exculpatory evidence if the prosecu-
tor was aware of that evidence or obtained it from another
source. See Moran, 54 F.4th at 492–93.
A criminal defendant who, like Mims, later becomes the
plaintiff in a civil suit under § 1983 faces an additional hurdle
when seeking damages for a Brady-based due process viola-
tion by a police officer. See id. at 493. In the civil context, “neg-
ligent conduct does not offend the Due Process Clause.” Id.

-- 9 of 15 --

10 No. 24-1564
(quoting Miranda v. County of Lake, 900 F.3d 335, 353 (7th Cir.
2018)). We consider evidence “suppressed in a § 1983 suit
only if a police officer ‘acted intentionally or at least reck-
lessly’ in failing to turn it over to the prosecution.” Id. To be
sure, we have not resolved whether reckless conduct can cre-
ate liability for a Brady suppression claim. See id. Nor does this
case require us to do so. We can proceed by assuming—and
without deciding—that “reckless failure to disclose exculpa-
tory evidence constitutes suppression.” Id.
B
Turning to the merits, Mims contends that Detectives
McNally and Przepiora violated Brady by suppressing—at all
stages of his prosecution in the Cook County Criminal
Court—the recording containing the discussion between Mel-
vin Richardson and Michael Sardin. Like the district court, we
cannot get there. Above all else, we agree that Mims has not
come forward with evidence that Detective McNally or De-
tective Przepiora concealed or otherwise withheld this re-
cording from ASA William Delaney.
One essential and undisputed fact stands out and war-
rants emphasis. At all times during the underlying prosecu-
tion, all five recordings made pursuant to COH 013, including
the recording of the Richardson-Sardin discussion Mims fea-
tures in his Brady claim, were available in a file at the Cook
County Circuit Court. Mims’s trial before Judge Toomin took
place in 2006. Five years earlier, in 2001, Judge Toomin or-
dered the impoundment of all original COH 013 recordings
with the Clerk of Court, with the accompanying directive that
the Cook County State’s Attorney’s Office keep a set of copies.
Discovery in this case confirmed that the original Richardson-

-- 10 of 15 --

No. 24-1564 11
Sardin recording was part of the Cook County Circuit Court
file.
The record also shows that ASA William Delaney and
Mims’s defense counsel, Daniel Franks, knew of the three
court orders authorizing the confidential recordings during
the Baker homicide investigation. Indeed, recall that ASA
Delaney produced the affidavits and orders related to all au-
thorized recordings (COH 003, COH 007, COH 013) as part of
discovery in the underlying criminal case. And, when it came
to COH 013, ASA Delaney provided Franks with two of the
five recordings.
The record further reveals that ASA Delaney not only un-
derstood that any recordings generated pursuant to Judge
Toomin’s confidential overhear orders would be impounded
at the Cook County Circuit Court, but that he also knew how
to access the impounded court files. Specifically, at a pretrial
hearing in August 2005, ASA Delaney made clear that he ex-
pected Judge Toomin to have sealed any recordings made un-
der COH 013. And, as he tried to identify whether recordings
existed pursuant to COH 003 or 007, ASA Delaney actually
obtained a judicial order on June 13, 2005 that directed the
Clerk of the Circuit Court to release to him any sealed and
impounded original recordings related to those two confiden-
tial overhears.
Make no mistake, we are not suggesting that ASA Delaney
knew that the COH 013 court file contained three recordings
beyond those he provided to Mims’s attorney in discovery.
But what we are saying is that the record leaves us no doubt
that the Cook County court file containing the COH 013 re-
cordings was itself known and accessible to ASA Delaney
prior to Mims’s criminal trial.

-- 11 of 15 --

12 No. 24-1564
Mims urges a different focus. He invites us to concentrate
on ASA Delaney’s specific unawareness of the key recording
of Richardson and Sardin and, from there, to conclude that
Detectives McNally and Przepiora concealed or otherwise
withheld that particular recording. On his account, Mims sug-
gests that the detectives had copies of all five recordings and
deliberately provided the prosecutor with an incomplete set,
thereby explaining why ASA Delaney only produced two of
the five recordings that made up COH 013.
But therein lies the analytical misstep. Mims is asking the
wrong party to shoulder responsibility for the failed disclo-
sure. The affirmative duty to discover and disclose exculpa-
tory evidence primarily falls to the prosecutor. “[O]nce the
prosecution has the evidence, it is the prosecution’s—not the
officer’s—duty to disclose it to the defense.” Moran, 54 F.4th
at 493. In no uncertain terms, the record shows that ASA
Delaney had knowledge of and access to the court file con-
taining the recordings that resulted from COH 013, including
the recording of the allegedly exculpatory Richardson-Sardin
discussion. Further, Judge Toomin had ordered the Cook
County State’s Attorney’s Office to maintain a full set of cop-
ies of the recordings.
On these facts, we do not see how the police were respon-
sible when the recording of Richardson and Sardin did not
end up in Mims’s counsel’s hands. Even if ASA Delaney re-
ceived (or expected to receive) copies of certain recordings
from the police, that fact would not relieve him of his affirm-
ative obligation to ensure the completeness of his disclosure,
especially given that he knew of COH 013 and had independ-
ent access to the complete recordings. On the record before
the district court, no reasonable jury could find that Detective

-- 12 of 15 --

No. 24-1564 13
McNally or Detective Przepiora concealed a recording that
was readily available to the prosecution through another
known source.
Nor, it is worth underscoring, does Mims provide affirm-
ative evidence that Detective McNally or Detective Przepiora
misled ASA Delaney by, for example, misdirecting or pre-
venting him from seeking a recording he could otherwise
have located and disclosed. Mims asks us to infer that ASA
Delaney relied on the detectives to obtain the two recordings
from COH 013 that he did produce to defense counsel Daniel
Franks which, in turn, supports the inference that the detec-
tives withheld the non-disclosed recordings. But this conten-
tion finds no footing in the summary judgment record devel-
oped in the district court. ASA Delaney could not recall the
source of the two recordings he disclosed, which—given
Judge Toomin’s March 2001 order—could plausibly have
been in a file within the State’s Attorney’s Office.
And the other evidence connecting Detectives McNally
and Przepiora to the recordings is too attenuated to support
Mims’s theory of suppression. The record shows that Detec-
tive McNally listened to the COH 013 recordings back in 2001.
But he denied creating copies and testified that he believed
the State’s Attorney’s Office retained possession of all record-
ings. To jump from his listening to the recordings to inten-
tional or reckless concealment is too speculative—especially
given that Detective McNally stopped working on the Baker
homicide investigation nearly three years before Mims’s ar-
rest. We also see no evidence showing that Detective McNally
aided ASA Delaney in gathering pretrial discovery.
Another piece of evidence deserves highlighting. At his
deposition in this case, Detective McNally testified that he

-- 13 of 15 --

14 No. 24-1564
thought the State’s Attorney’s Office had possession of the
COH 013 recordings after he listened to them and that, even-
tually, the Cook County Court impounded all recordings. De-
tective McNally therefore had reason to believe all five COH
013 recordings would be available to the prosecution regard-
less of his actions, undermining his motive to intentionally or
recklessly conceal the recordings. See Moran, 54 F.4th at 495
(reasoning that a police officer who knew of another agency’s
obligation to send a particular report to the prosecution
“could not have thought that he had the power to conceal the
report,” corroborating his claim to have mistakenly failed to
send it to lead detectives). In short, the record does not sup-
port an inference that Detective McNally acted with either
mental state required for Mims to succeed on his § 1983 civil
Brady claim.
We have even more difficulty with Mims’s Brady claim
against Detective Przepiora. We see no evidence suggesting
that Detective Przepiora ever knew about the Richardson-Sar-
din recording. That evidentiary gap leaves us with no choice
but to uphold the district court’s entry of summary judgment
for Detective Przepiora.
We have also considered whether the recording of Melvin
Richardson and Michael Sardin is material within the mean-
ing of Brady. On one view, Mims was already on notice that
Sardin and others may have been involved in the murder be-
cause his counsel, Daniel Franks, received the affidavits sup-
porting the application for COH 013. Mims insists that Sar-
din’s admission in recorded form would have made a differ-
ence. See Moran, 54 F.4th at 496 (“The form of evidence pro-
duced is only relevant for Brady purposes when evidence in
one form would be more helpful to the defense than evidence

-- 14 of 15 --

No. 24-1564 15
in another form….”). Ultimately we need not reach this ques-
tion because the materiality of evidence is not relevant under
Brady unless evidence is suppressed. We resolve this appeal
based solely on Mims’s failure to show that either Detective
McNally or Detective Przepiora concealed or otherwise with-
held the recording. This conclusion likewise obviates any
need to go further and reach the alternative reasoning of the
district court regarding qualified immunity.
* * *
In the final analysis, then, we agree with the district court’s
entry of summary judgment for Detectives McNally and Prze-
piora. We do not reach this conclusion lightly, for we fully
understand Mims’s desire to hold someone accountable for
his wrongful conviction. But we must decide the case on the
law as it stands and on the factual record developed in the
district court. Mims’s Brady claim fell short, leaving us no op-
tion but to AFFIRM.
