Chicago – Two counts of first-degree murder have been filed against a 21-year-old Southside man in the separate Eastside killings of two young women more than a year apart, Chicago police said.
Anthony D. Nunnally, of the 9500 block of South Bennett Avenue, is accused of fatally shooting Sierra Evans, 19, on Sept. 28, 2024, and Gabriela “Gabby” Arellano, 17, on Oct. 26, 2025, according to charging documents.
Nunnally was 19 at the time of Evans’ killing and 20 when Arellano was killed.
According to the Chicago Police Department, members of the Homicide Investigations and Support Team arrested Nunnally on Aug. 3, 2026, and listed the arrest location as the 2700 block of South California Avenue.
Cook County Department of Corrections records show he was already in custody on a pending carjacking case when the murder charges were filed.
Sierra Evans Homicide
According to investigators, Sierra Evans, 19, was found unresponsive about 9:30 a.m. Sept. 28, 2024, in the 9500 block of South Avenue N with gunshot wounds to her body.
She was pronounced dead at the scene.
Evans’ killing drew citywide attention days later after officials revealed that the now-defunct ShotSpotter system had reportedly detected gunfire in the area at 12:06 a.m. on Sept. 28, 2024.
Nine hours later, Evans was found dead in an alley.
According to WGN News, Ald. Peter Chico confirmed with SoundThinking, ShotSpotter’s parent company, that the system recorded the gunfire.
Chicago’s contract with ShotSpotter had ended on Sept. 23, 2024, and the company was no longer sending alerts to police.
Family members and several alderpersons argued the technology may have resulted in an earlier police response.
Authorities, have never stated whether an earlier response would have changed the outcome of the case.
Gabriela Arellano Homicide
Police allege Nunnally fatally shot Gabriela Arellano, 17, on Oct. 26, 2025.
Arellano was found unresponsive shortly after 10:15 a.m. in an alley in the 11000 block of South Mackinaw Avenue with two gunshot wounds to the head, authorities said.
She was pronounced dead at the scene after having been missing for more than a week.
According to the Chicago Tribune, her mother dropped the 17-year-old off near 106th Street and Avenue O on the afternoon of Oct. 17, 2025.
She was expected to return home that day but stopped answering phone calls, using social media, or reporting to her job at a nearby convenience store.
Her mother filed a missing persons report on Oct. 21.
Private surveillance footage captured about 1:12 a.m. on Oct. 26 showed the 17-year-old walking southbound in the alley with two unidentified people wearing hooded sweatshirts and face masks.
She appeared to stop before walking toward the pair on the west side of the alley.
Moments later, the two individuals ran southbound through the alley. A nearby home security camera recorded the sound of a single gunshot.
Three people discovered her body later that morning.
Police have not released a possible motive in either killing or said whether the two victims knew each other.
So far, the only publicly disclosed link between the homicides is the allegation that Nunnally is responsible for both.
Pending Vehicular Hijacking Case
At the time he was charged in the homicides, Nunnally was already being held in the Cook County Jail on an aggravated vehicular hijacking case involving a firearm.
According to Chicago police arrest records, Nunnally was taken into custody about 9:22 a.m. Oct. 28, 2025, in the 14432 block of Irving Avenue and booked under CB No. 30521899.
He was charged with aggravated vehicular hijacking with a firearm in violation of 720 ILCS 5/18-4(a)(4).
The charge stems from an Oct. 2, 2025, armed carjacking of a 19-year-old man in the 12900 block of South Muskegon Avenue in the Hegewisch neighborhood.
Investigators said Nunnally was apprehended by Chicago police officers working with the U.S. Marshals Great Lakes Regional Fugitive Task Force.
Cook County Department of Corrections records show Nunnally has been in custody in Division 5 since Oct. 30, 2025. His next scheduled court appearance is Aug. 10, 2026, at the Leighton Criminal Courts Building.
Police said no additional information regarding the homicide investigations is available at this time.
