IN THE
APPELLATE COURT OF ILLINOIS
FIRST DISTRICT
THE PEOPLE OF THE STATE OF ILLINOIS,
Plaintiff-Appellee,
v.
CORTEZ DUFFY,
Defendant-Appellant.
Appeal from the Circuit Court of Cook County
No. 25 CR 0204001
The Honorable Tyria B. Walton, Judge, Presiding
JUSTICE OCASIO delivered the judgment of the court.
Justices Mitchell and Navarro concurred in the judgment.
ORDER
¶1 Held: The trial court properly denied defendant charged with first degree murder pretrial
release where the facts before the court on proffer showed, clearly and convincingly,
that the evidence against defendant was strong; that release would pose a danger to
the victim’s girlfriend, who previously had a romantic relationship with defendant;
and that any threat to her safety would not be adequately mitigated by release
conditions.
¶2 The defendant, Cortez Duffy, appeals from a series of orders entered between January 2025
and April 2026 under which he has been denied release pending trial for the first degree murder of
Tyrone Shelton. We find that the State met its burden of showing, by clear and convincing
evidence, each element necessary to deny pretrial release based on dangerousness. See 725 ILCS
5/110-6.1(e)(1) to (3) (West 2024).
¶3 I. BACKGROUND
¶4 A brief procedural history. After Duffy was arrested and charged, the State filed a petition to
deny him pretrial release. The court granted the petition and ordered that Duffy remain in detention
pending trial. In June 2025 and again in September 2025, Duffy petitioned for his release. The
court denied both petitions and ordered Duffy’s continued detention. After the second denial, Duffy
appealed from both the June and September orders, but we found that neither of his petitions
amounted to motions for relief, so we dismissed the appeal. People v. Duffy, 2026 IL App (1st)
252181‑U; see Ill. S. Ct. R. 604(h)(2) (eff. Apr. 15, 2024). After the mandate issued, Duffy filed a
motion for relief, which was heard and denied in April 2026. Duffy is now appealing from the
initial order denying pretrial release and the three subsequent orders denying his petitions.
¶5 At all four hearings, both parties proceeded by proffer (with the sole exception of an affidavit,
which is discussed below). Rather than detail the proffers at each hearing, we will relate what the
proffers showed as a whole at the time of the April 2026 hearing.
¶6 Duffy was previously in a romantic relationship with Martanic Morris. They had one child
together, a girl named K***. At the time of the charged incident, Morris had started dating Shelton.
¶7 Late in the evening of September 17, 2024, Morris returned to her apartment building with
K. and accompanied by Shelton. They found Duffy waiting outside Morris’s apartment. There were
words exchanged, and Duffy snatched K. from Morris and tried to flee. Shelton drew a gun and
gave chase. Duffy gave K. back to Morris, who brought her into the apartment. Shelton followed.
Duffy started breaking the windows of Morris’s car. She called the police, but Duffy was gone by
the time they arrived.
¶8 At some point after departing, Duffy sent Morris a text message threatening to kill both her
and Shelton.
-2-
¶9 At around midnight, Shelton left Morris’s apartment to move her car. He was shot dead on
the sidewalk before he returned. Morris heard a gunshot from inside her apartment and looked out
the window and saw Shelton on the ground. She called 911 and told them that Duffy had shot
Shelton. She said the same thing to responding police officers. It is not clear from the proffers
whether she told the operator and the officers that she saw Duffy or merely relayed her suspicion
that Duffy was responsible. Scene investigators found seven spent shell casings on the ground and
a gun in Shelton’s pocket. The casings matched each other, but they did not match Shelton’s gun.
¶ 10 License plate readers recorded Duffy’s car in the vicinity before the shooting, and a
surveillance camera captured him parking behind Morris’s building and walking around toward
the front just before Shelton was killed.
¶ 11 About three months after the shooting, there was an incident in which Duffy struck Morris
several times, broke the windows of her car, and also slashed the tires. The record divulges no
further detail about that incident.
¶ 12 Morris has given conflicting statements about whether she saw Duffy when she looked out
the window. After her initial statements on-scene, it appears that she told investigators (when and
who are not clear) that she did not see the shooter. Several days later, though, she gave a videotaped
statement in which she said that she saw Duffy shoot Shelton. About 11 months after the shooting,
Morris gave a signed statement to a defense investigator. In that statement, she said that she did
not see the shooter when she looked out the window, and she explained that she had told the police
otherwise only after a detective threatened to have her arrested as an accomplice and have K. sent
to foster care.
¶ 13 The record discloses that Duffy has five felony convictions on his record. Four of those
convictions were for possession of a controlled substance; the fifth was a 2012 conviction for
escape from electronic home confinement. He has two misdemeanor convictions for cannabis
possession and one for driving on a suspended license. He was also arrested in 2004 after his
mother signed a complaint alleging that he struck her and threatened to kill her. The public safety
-3-
assessment completed by pretrial services at the time of the first detention hearing recommended
release with “supervision level 3” (though the record does not disclose what that would entail).
¶ 14 At the time of his arrest, Duffy lived with his wife of ten years, who worked full-time as a
nurse. Duffy was the primary caregiver for their two children, and before that he had worked as a
janitor. He had neither a driver’s license nor a passport. He had lived in the Chicago area his entire
life, and he had no gang affiliations. As of the most recent hearing in the record, which was held
in April 2026, Duffy had not had any disciplinary issues while in pretrial detention at the county
jail.
¶ 15 II. ANALYSIS
¶ 16 On appeal, Duffy challenges the factual basis for denying him pretrial release. All defendants
are presumed to be eligible for release pending trial, and release can only be denied if the State
rebuts that presumption by clear and convincing evidence. 725 ILCS 5/110-6.1(e) (West 2024).
Here, the basis for denying pretrial release was that Duffy’s release would pose a danger to the
public or to a specific person. When that is the basis for denying release, the State must clearly and
convincingly show (1) that the proof was evident or the presumption great that the defendant
committed a detainable offense, (2) that the defendant’s release would pose a real and present
threat to the safety of any person, persons, or the community, and (3) that no set of release
conditions can mitigate that threat. See 725 ILCS 5/110‑6.1(e)(1) to (3) (West 2024). “Evidence is
clear and convincing if it leaves no reasonable doubt in the mind of the trier of fact as to the truth
of the proposition in question.” Chaudhary v. Department of Human Services, 2023 IL 127712,
¶ 74. That standard requires proof greater than a preponderance of the evidence but not quite
approaching the criminal standard of beyond a reasonable doubt. People v. Lee, 2024 IL App (1st)
232137, ¶ 18.
¶ 17 On appeal, Duffy argues that the State failed to meet its burden on each of the three elements.
As the parties proceeded by proffer and documentary evidence only, our review is de novo.
People v. Morgan, 2025 IL 130626, ¶ 45.

¶ 18 A. Evident Proof or Great Presumption of Guilt
¶ 19 The first proposition that the State must show by clear and convincing evidence is that “the
proof is evident or the presumption great that the defendant has committed” the detainable offense
charged. 725 ILCS 5/110‑6.1(e)(1) (West 2024).
¶ 20 Duffy argues that the State has not made a strong enough showing that he was the person who
shot and killed Shelton. His argument hinges on Morris’s changing accounts of what she personally
observed at the time of the shooting versus what she merely inferred. The State proffered that
Morris gave a statement after the shooting in which she specifically said that she heard a gunshot,
looked out the window, and saw Duffy standing over a prone Shelton and shooting him two or
three more times. The defense proffered that Duffy has, at other times, said that she did not see the
shooter but assumed under the circumstances that it was Duffy. It also introduced a sworn affidavit
in which Morris averred that she did not see the shooter and only told the police that she had after
they threatened to arrest her as an accomplice and have her daughter taken from her and placed
into foster care.
¶ 21 If all the State had was Morris’s disavowed statement, that might not have been enough to
carry its burden. But the State also proffered, without contradiction, that license plate readers
recorded Duffy’s vehicle in the vicinity before the shooting and that a surveillance camera captured
him parking behind Morris’s building and walking around to the front of the building, which is
where Shelton was shot. Based on the earlier altercation, Duffy had a clear motive for shooting
and killing Shelton, and, in fact, had threatened to do so shortly before Shelton was killed. Duffy
dismisses these facts as “circumstantial,” but the circumstances proffered here are damning. Even
discounting Morris’s identification of Duffy as the shooter, the State has carried its burden of
showing that the proof is evident and the presumption great that Duffy committed the charged
murder of Shelton.

¶ 22 B. Dangerousness
¶ 23 The second proposition that the State must show by clear and convincing evidence is that “the
defendant poses a real and present threat to the safety of any person or persons or the community,
based on the specific articulable facts of the case.” 725 ILCS 5/110‑6.1(e)(2) (West 2024).
¶ 24 The evidence proffered readily showed that Duffy’s release would, at minimum, pose a threat
to Morris. It is undisputed that, on the evening of September 17, 2024, Duffy went to Morris’s
apartment, where he confronted her, forcibly took their daughter from Morris, and attempted to
flee. When his efforts were thwarted, he broke the windows of her car, a common tactic domestic
abusers use to threaten or terrorize a victim. See D. Kelly Weisberg, Property Damage in the
Domestic Violence Context, 22 Domestic Violence Rep. 17, 17, 28 (2017). The State’s proffer
further showed that he then sent Morris a threat to kill her and Shelton and then returned to her
residence armed with a gun that he used to make good on that threat, murdering Shelton in the
street. The proffer also showed that, in a separate incident three months later, Duffy attacked
Morris and again damaged her car, this time slashing the tires in addition to breaking the windows.
¶ 25 In his motion for relief, Duffy argues that he does not pose a threat to any person’s safety
because, should he be released, he would return to his role as a stay-at-home father and the primary
caregiver for two of his children. The need to care for his other children did not stop him from
going out of his way to assault Morris twice in the months before his arrest, so we fail to see how
that means his release would not pose a threat to her safety. The State has met its burden as to
dangerousness.
¶ 26 C. No Adequate Conditions of Release
¶ 27 The final proposition that the State must show by clear and convincing evidence is that “no
condition or combination of conditions [of release] can mitigate *** the real and present threat to
the safety of any person or persons or the community, based on the specific articulable facts of the
case.” 725 ILCS 5/110‑6.1(e)(3) (West 2024).
¶ 28 The most salient fact here is that Duffy’s criminal history includes a conviction for escape
from electronic home monitoring. He has a demonstrated record of violating the conditions of his
-6-
monitoring or home confinement. The proffered facts of the charged offense show that he is able
and willing to arm himself illegally (his record of felony convictions makes it a crime for him to
have a gun). They also show that his responsibilities at home, whatever they may be, do not provide
him with enough of a disincentive to keep him from accosting Morris and engaging in acts of
violence—even deadly violence—against her and those around her. We agree with the trial court
that the nature of the threat that Duffy’s release would pose to Morris cannot be adequately
mitigated by release conditions. The State has met its burden on this element.
¶ 29 III. CONCLUSION
¶ 30 Taking into account all of the facts proffered by the parties, the State has shown by clear and
convincing evidence that Duffy committed a detainable offense, that his release pending trial
would pose a real and present threat to Morris’s safety, and that there are no set of release
conditions that would adequately mitigate that potentially deadly threat.
¶ 31 Accordingly, we affirm the trial court’s orders denying pretrial release, denying the various
motions for release or relief, and requiring Duffy’s continued detention pending trial.
¶ 32 Affirmed.
