A teenager has been arrested after he allegedly shot and killed a 16-year-old at a party in Snellville over the weekend, officials said Monday.

Keegan Gates, 17, of Decatur, was booked into the Gwinnett County Jail on charges of felony murder, aggravated assault, possession of a firearm during the commission of a felony and possession of a firearm by a person under 18, the GBI said.

Snellville police responded to the 1900 block of Scenic Highway around 10:45 p.m. Saturday after getting a report of a fight among a large number of people.

As officers were arriving, they heard gunshots and came across a teen shot in the chest, police said. The victim, Nasir Davis of Lithonia, was taken to the hospital, where he died, the GBI said. The Gwinnett Medical Examiner’s Office will perform his autopsy.

According to the GBI, a party was being held at the location that evening and Gates is accused of shooting Davis during the fight, officials said. The teens were believed to have known each other, the state agency added.

On Sunday, police asked the GBI to investigate. After the probe is completed, the case file will be given to the Gwinnett District Attorney’s Office.

Anyone with more information is asked to contact Snellville police at 770-985-3555, or the GBI’s Atlanta office at 770-388-5019.
