The victims were killed nearly 13 months apart, and authorities have not said whether the shootings were otherwise connected.
CHICAGO — Two East Side homicide investigations that began nearly 13 months apart have led to first-degree murder charges against the same Chicago man, while key questions about the shootings and any possible connection remain unanswered.
Anthony Nunnally, 21, is accused of killing Gabriella Marie Arellano, 17, in October 2025 and Sierra Evans, 19, in September 2024. Chicago police announced two murder charges Tuesday after identifying Nunnally as the alleged gunman in both Far South Side cases.
The earlier shooting occurred Sept. 28, 2024, in the 9500 block of South Avenue N. Police found Evans suffering from multiple gunshot wounds. Authorities have not publicly detailed the circumstances that brought her to the location or identified a suspected motive.
More than a year later, officers found Arellano in an alley in the 11000 block of South Mackinaw Avenue on Oct. 26, 2025. Police said she had been shot twice. Her death opened a separate homicide investigation in the same neighborhood.
The locations are both in the East Side community, but police have not said whether the women knew each other or shared any relationship with Nunnally. Authorities also have not said whether investigators believe the shootings arose from similar circumstances.
The charges bring the separate investigations into the same criminal proceeding, but the information released by police leaves much of the investigative timeline unclear. Authorities have not explained when Nunnally first became a suspect, what evidence linked him to each shooting or whether information from one case helped advance the other.
Police said Nunnally was taken into custody Monday in the 2700 block of South California Avenue. He was already being held at the Cook County Jail on separate felony carjacking and armed robbery charges when the murder cases were announced.
Nunnally is presumed innocent unless proved guilty. No plea in the murder cases was reported, and publicly available accounts did not name a defense attorney representing him on the new charges.
The investigation has not produced a publicly stated motive, and officials have not released information about a weapon, forensic testing or possible witnesses. Those details may emerge through court filings or future hearings, but no additional disclosures had been announced.
Nunnally was due in court Wednesday for a detention hearing. The cases will move forward separately from the unresolved carjacking and robbery allegations already pending against him.
