Tyson Barnett, 40, was killed in a southwest Atlanta parking lot after a dispute on the morning of June 6, 2020. Officers found him in the 3900 block of Campbellton Road suffering multiple gunshot wounds; he was taken to Grady Memorial Hospital and later pronounced dead.

Investigators say the shooting followed an argument between Barnett and another man and escalated into a shootout. It has not been determined who fired first. The suspect fled in a silver vehicle, possibly a Nissan, and no arrests have been announced.

Anyone who was near the apartment complex on Campbellton Road that morning or who has information about the silver vehicle is asked to come forward.
