Prosecutors have accused a Chicago man of murdering two of his girlfriends, one in 2024 and another the following year, leaving their bodies outside for hours before they were discovered.
The victims were found in areas formerly monitored by the city’s ShotSpotter system. Despite this, no 911 calls were made to report the gunfire, and the police only became aware of the murders after the victims were found by residents or passersby. These cases are part of CWBChicago’s “Brandon’s Bodies” series, which investigates the impact of dismantling the city’s gunfire detection system on emergency responses and victim discoveries.
On September 28, 2024, five days after Mayor Brandon Johnson severed ties with ShotSpotter, Chicago police were alerted by a 911 call about an unresponsive woman on the 9500 block of South Avenue N.
The woman was identified as 19-year-old Sierra Evans, who had been shot. Police found 18 shell casings near her body.
Prosecutors allege that Evans’ then-boyfriend, Anthony Nunnally, 21, was responsible for her death. They had been dating for several weeks and were with two other individuals at a nearby home on the night of the shooting.
Nunnally allegedly choked and assaulted Evans, leading the others to eject him from the home. He later called them, saying he was taking an Uber home. Shortly after, gunshots were heard outside. Nunnally reportedly returned to the basement with a gun, claiming he had committed a murder.
Evans’ body remained in the alley until a 911 call prompted first responders to investigate.
Nunnally subsequently dated another woman and allegedly used a news report about Evans’ death to threaten her, claiming he would do the same to her.
Thirteen months later, Nunnally is accused of killing another girlfriend, 17-year-old Gabriella Arellano. Her body was found with a gunshot wound to the head in an alley behind the 11000 block of South Mackinaw Avenue on October 26, 2025. Again, no 911 calls reported the gunfire.
Surveillance footage allegedly shows Nunnally, Arellano, and another individual walking in the area prior to the shooting. The video captures a gunshot, followed by Nunnally fleeing with the other person.
Nunnally was arrested by Chicago police two days later in connection with Arellano’s murder. However, prosecutors initially charged him with an unrelated armed carjacking. He has been in Cook County Jail for the carjacking case since then.
Prosecutors enlisted Nunnally’s cellmate, a former member of his street gang, the Latin Kings, to wear a recording device to elicit information about Arellano’s death. During the recorded conversation, Nunnally allegedly expressed belief that Arellano intended to set him up for a rival gang. When asked if he regretted the killing, Nunnally reportedly replied, “You gotta do what you gotta do.”
Judge Deidre Dyer has ordered Nunnally to be held for both murder cases, in addition to the carjacking charge.
