Chicago man charged in murders of 2 teen girlfriends in 2024, 2025; admitted to crimes in jail, prosecutors say

A man has been charged with murder in the shooting deaths of two teens in the East Side neighborhood on the Far South Side of Chicago in 2024 and 2025.

Anthony Nunnally, 21, is charged with two counts of first-degree murder.

Police said he was identified as the gunman who shot and killed a 17-year-old Gabriella Marie Arellano in the 11000 block of South Mackinaw Avenue on Oct. 26, 2025.

Nunnally also was identified as the gunman who shot and killed 19-year-old Sierra Evans on Sept. 28, 2024, police said.

Appearing in court Wednesday, prosecutors outlined the circumstances they said led up to each girl's death.

According to prosecutors, Nunnally was a gang member and had been dating both girls at the times of their deaths.

In 2024, prosecutors said Nunnally was out with Evans, his girlfriend of about a month at the time, and two other people and had been drinking. They want back to a home where prosecutors said Nunnally got angry, accused one of the people there of stealing his marijuana, choked Evans when she did not defend him, and punched a hole in the wall. He was told to go home and his mom picked him up, prosecutors said.

However, prosecutors said Nunnally later Facetimed one of the people in the home and told them he was coming back to their house and to leave the back door open.

Witnesses said they heard the sound of automatic gunfire and hen asked what happened, Nunnally, using a derogatory term for an African American, said he just shot someone and flashed and gang side, according to prosecutors.

Evans' body was found the next day in the 9500 block of South Avenue N with multiple gunshot wounds, according to police.

About a year later, in 2025, Arellano's mother dropped her daughter off on the Far South Side, the last time she'd see her alive. Nunnally had been dating Arellano for a short time when he allegedly killed her.

According to prosecutors, the two went out to dinner with another person. Prosecutors said they were seen on surveillance video at the restaurant.

Later, in a nearby vacant lot, prosecutors said a Ring doorbell camera captured the sound of a single gunshot and then Nunnally and another person running away. Arellano's body was found in that vacant lot, prosecutors said.

Days later, Nunnally was arrested and charged for an unrelated armed carjacking that happened before Arellano's death. He was already being held in Cook County Jail for that carjacking and armed robbery arrest when the murder charges were filed.

Prosecutors said Nunnally admitted what he'd done to another member of the same gang in the jail who was wearing a wire. According to prosecutors, Nunnally told this other person he had no choice but to kill Arellano because she was going to "back-door" him – which means to betray or kill him. Prosecutors said he told the gang member she was going tell a rival gang his location.

The judge noted Nunnally has unlawfully had guns he wasn't supposed to have many times; three times as an adult, and twice as a juvenile.  Nunnally returned to the Cook County Jail after the hearing. His next court date is scheduled for Aug. 26.
