The 18-year-old was identified as Erin Harrison, according to Atlanta police. Investigators, who had released a sketch in the hopes someone would recognize him, had estimated he was between 13 and 17 years old.
Two people were shot when gunfire erupted about 10 p.m. on Oct. 9 in the 3500 block of Sherbrooke Way, located in a subdivision off Hogan Road. The teenager, believed to be the aggressor, was found dead outside the home when police arrived, authorities said. The second gunshot victim, a 35-year-old man, was conscious when he was taken to Grady Memorial Hospital.
