Police linked Anthony Nunnally to separate shootings that killed Gabriella Arellano, 17, and Sierra Evans, 19.
CHICAGO — A 21-year-old Chicago man has been charged with first-degree murder in two separate East Side shootings that killed a teenage girl and a young woman nearly 13 months apart, police said.
Anthony Nunnally faces two counts of first-degree murder in the deaths of Gabriella Marie Arellano, 17, and Sierra Evans, 19. Chicago police announced the charges Tuesday, marking a new stage in investigations that began after the women were found fatally shot in different parts of the Far South Side neighborhood.
Police said Arellano was killed Oct. 26, 2025, in the 11000 block of South Mackinaw Avenue. Officers found her in an alley with gunshot wounds. Authorities later identified Nunnally as the person accused of shooting her, but police have not publicly described the evidence that led investigators to him.
Evans was killed Sept. 28, 2024, in the 9500 block of South Avenue N. Police said she was found with multiple gunshot wounds. Investigators also identified Nunnally as the alleged gunman in that case.
The two shootings happened in the same general area but at different locations and during different years. Police have not said whether Arellano and Evans knew each other, whether either woman knew Nunnally or whether investigators believe the killings were connected beyond the accusations against the same defendant.
Nunnally was taken into custody Monday in the 2700 block of South California Avenue, police said. At the time, he was already being held at the Cook County Jail in connection with separate felony carjacking and armed robbery allegations.
The murder charges are accusations, and Nunnally has not been convicted in either killing. Publicly available reports did not identify an attorney who could comment on his behalf.
Authorities have not released a possible motive for either shooting. Police also have not disclosed whether the same weapon was involved, what forensic evidence was collected or how investigators connected Nunnally to cases that occurred nearly 13 months apart.
Nunnally was scheduled to appear in court Wednesday for a detention hearing. A judge was expected to consider whether he should remain in custody while the murder cases move through the Cook County court system.
