JUSTICE COBBS delivered the judgment of the court. Presiding Justice Fitzgerald Smith and Justice Lavin concurred in the judgment.

ORDER

¶1 Held: Defendant’s conviction and sentence for first-degree murder is affirmed. The trial court did not err by acting impartially, admitting firearm identification evidence without a Frye hearing, or denying defendant’s request for a continuance. Additionally, the State did not make improper comments during cross-examination or closing argument, and defendant’s sentence did not violate the proportionate penalties clause of the Illinois Constitution.

¶2 Following separate but simultaneous jury trials, defendant Jayton Dorsey and his cousin,

codefendant Timothy Gordon, were each convicted on three counts of first-degree murder and No. 1-23-0035

sentenced to mandatory terms of life in prison. 1 Defendant now appeals, arguing that (1) the trial

court erred in denying his motion for a Frye hearing on firearm identification evidence, (2) the

trial court acted as an impartial advocate for the State, (3) the State made several improper remarks

during cross-examination and closing argument, (4) the trial court erred in denying his posttrial

request for a continuance, and (5) his life sentence violates the proportionate penalties clause of

the Illinois Constitution as applied to him. For the following reasons, we affirm.

¶3 I. BACKGROUND

¶4 The charges in this case arose from the June 30, 2017, shooting deaths of Javon Jackson,

Sedrick Ringer, and John Hunter. The evidence showed that the victims were killed by a barrage

of gunfire while standing outside a building in the 5700 block of South Wells Street in Chicago.

¶5 A. Motion to Exclude Firearm Identification Evidence

¶6 Prior to trial, defendant filed an extensive, 75-page motion in limine seeking to exclude the

testimony of forensic firearms examiner Jennifer Sher. The motion cited reports from various

scientific bodies casting doubt on the efficacy of firearm identification, the practice of

microscopically examining fired ammunition to determine whether it was fired from a particular

gun. Defendant also asserted that firearm examiners were prone to false positives for a variety of

reasons such as cognitive bias. For these reasons, defendant argued that firearm identification

“cannot be said to enjoy wide-spread scientific acceptance, nor to possess reliability sufficient to

overcome the prejudicial and overblown statements of its practitioners.” Although defendant

acknowledged that Illinois courts have long admitted firearm identification evidence, he contended

that the field could no longer withstand scrutiny in light of the recent evidence cited in his motion.

1 This court affirmed Gordon’s convictions and sentence in a separate appeal. People v. Gordon, 2025 IL App (1st) 230037-U. He is not a party to this appeal.

-2- No. 1-23-0035

Defendant therefore requested that the trial court either exclude any testimony regarding firearm

identification or conduct a pretrial hearing pursuant to Frye v. United States, 293 F. 1013 (D.C.

Cir. 1923), to assess the general acceptance and reliability of the firearms evidence.

¶7 In response, the State argued that a Frye hearing was unnecessary because the

methodologies in question were not new or novel and have been routinely admitted by Illinois

courts. The State also cited People v. Robinson, 2013 IL App (1st) 102476, ¶ 91, where this court

considered many of the criticisms raised in defendant’s motion and concluded that the trial court

in that case did not err in admitting expert testimony on firearm identification without first holding

a Frye hearing.

¶8 After hearing arguments from the parties, the trial court denied defendant’s motion. The

court stated the firearms evidence would be admitted without a Frye hearing because the

examinations were “of a type that is generally accepted in the field to which it belongs.”

¶9 B. Jury Trial

¶ 10 At trial, Michael Graves testified that he heard the gunshots from his home on South Wells

just before 9 p.m. on June 30, 2017. As he approached the window to check on the noise, Graves

noticed “a couple of muzzle flashes” and “maybe two people” shooting firearms. However, the

shooters quickly fled and Graves did not see their faces. Graves was able to describe the shooters

only as “African-American males.”

¶ 11 Detective Mark Campbell testified that he and his partner, Officer Krista Hinton, were on

patrol near South Wells at the time of the shooting. When they heard the gunshots, the officers

immediately activated their emergency equipment and drove toward the source of the noise. As

they approached South Wells, Detective Campbell saw “two or three males” firing guns at a

residence from the sidewalk.

-3- No. 1-23-0035

¶ 12 The shooters then ran south toward 58th Street, which was the next block over. As the

officers pursued in their vehicle, they noticed a white Pontiac parked on 58th Street. Detective

Campbell testified that two men inside the Pontiac “looked like” the people he had just seen

shooting firearms.

¶ 13 The Pontiac then drove off and entered the Dan Ryan Expressway “at a high rate of speed.”

The officers followed the Pontiac down the expressway as it “weav[ed] in different lanes” to avoid

slower traffic. Eventually, the Pontiac spun out of control and crashed onto a grassy hill on the

side of the expressway. As Detective Campbell exited his vehicle and approached the crash site,

he saw two people from the Pontiac run up the hill and climb a barbed wire fence surrounding an

IDOT parking lot.

¶ 14 Detective Campbell and Officer Hinton secured the area around the crashed Pontiac and

waited for backup to arrive. During that time, Detective Campbell observed a handgun in plain

view in the backseat of the Pontiac. The State introduced into evidence video footage from the

officers’ squad car, which substantially corroborates Detective Campbell’s testimony. 2 With the

help of a police helicopter, defendant and Gordon were subsequently found and arrested while

attempting to hide on the back deck of a residence on 66th Street. Footage from the helicopter and

the arresting officers’ body-worn cameras were also introduced into evidence.

¶ 15 Shortly after the arrests, at approximately 9:44 p.m., Detective Joseph Murtaugh

administered gunshot residue (GSR) collection kits for defendant and Gordon. These kits were

2 The video footage was not included in the record on appeal in this case, but was made part of the record on appeal in codefendant Gordon’s case. We take judicial notice of the video exhibits.
