Milton police say they now believe robbery was the motive in the shooting death of a 19-year-old in front of his home.
Investigators said the teen was in the driveway of his family's home when someone shot him in the head. Crews transported him to the hospital, where he later died.
Wednesday morning, the Fulton County Medical Examiner's Office identified the victim as Alpharetta High School graduate Christopher Walker. His family declined to speak with a Channel 2 Action News crew.
Police said the shooting happened shortly before 7:30 p.m. Tuesday outside a home on Silhouette Court in the Avensong subdivision, but did not know of a motive.
"We anticipate it is a random stranger-on-stranger crime", Captain Shawn McCarty said, "It did occur in the victim’s driveway."
McCarty said the teen was alone while his mother and a friend were inside the home. Investigators interviewed witnesses to get a description of the suspect and try to determine who would want to hurt the teen.
In the incident report released Wednesday morning, police said they believe robbery was the motive to the shooting.
"That just brings chills," said neighbor Mark Hogan. He heard police sirens and talked to other neighbors on the street who reported seeing a man run to a waiting car.
"She saw the guy actually running across her yard with a pistol in his hand," Hogan said.
Police said they have not identified a suspect in the slaying.
This is the seventh murder investigation in Milton in the last six years.
