Hector Rostro, 20, also was indicted on a charge of tampering with evidence. He is being held on $40,000 bond. The incident occurred on May 13, 2017, in the vicinity of Macon Road and Highland.
An investigation showed that Rostro was seated behind 18-year-old Miguel Angelayala Jr. in the vehicle while a third person was driving. Rostro told investigators he had a handgun on his lap and that when he reached for a cigarette the gun accidentally discharged, firing a bullet through the front passenger seat and striking Angelayala in the back.
They drove to Methodist Hospital North for help, but Angelayala was pronounced a short time later. Rostro told investigators he later threw the gun into a wooded area.
