An argument between two men Thursday morning led to a shooting that left one of them dead on a dead-end street in southwest Atlanta, according to police.

Officers were called to Cooper Street near Fulton Street in the Mechanicsville neighborhood around 3:30 a.m., Atlanta police Lt. Andrew Smith told The Atlanta Journal-Constitution from the scene. A homeless encampment is in that area.

When police arrived, they found the victim already dead. His name was not released.

It’s not clear what sparked the shooting, but Smith said investigators believe a confrontation took place between two men in their 40s and 50s. Authorities were still collecting evidence and talking to witnesses around 6:30 a.m.

No other details have been released about the incident.
