A youth accused of fatally shooting a 9-year-old last week has turned himself in and is facing multiple charges.

Atlanta police announced Sunday that they made an arrest Saturday in the boy’s death. Charges against the suspect include second-degree murder, aggravated assault and possession of a firearm during the commission of a felony.

While police did not indicate the suspect’s age Sunday, investigators soon after the shooting said they believed a 16-year-old pulled the trigger.

The minor was transported to the Youth Detention Center without incident, police said.

Around 10 p.m. Wednesday, officers were called to The Station at Richmond Hill apartment complex in the 1700 block of Richmond Circle in southeast Atlanta, according to Lt. Ralph Woolfolk, Atlanta police’s Homicide Unit commander. The boy died at the scene, Woolfolk said.

The child was identified as Kemoni Mack of Atlanta, the Fulton County Medical Examiner’s Office said. He was the fifth child under the age of 18 shot to death in Atlanta this year, according to police.
