More than a month after a 17-year-old was found shot dead in a wrecked car in DeKalb County, another teenager has been arrested on a charge of murder, officials said Wednesday.

Isaiah Artis, of Lithonia, was found July 17 after his car crashed into a telephone pole on Ashley Lane in Stone Mountain, the DeKalb County Sheriff’s Office said in a news release. The teenager had already been killed by a gunshot to the head.

Tremale Leeshon Hester, 19, of Stone Mountain, was arrested Tuesday in connection with Artis’ killing, the sheriff’s office said. He was located at a fast-food restaurant on South Deshon Road in Lithonia.

Officials have not said what led to the fatal shooting or how they connected Hester to the incident.

Hester was booked into the DeKalb County Jail, where he remains without bond.
