Atlanta police are investigating after a man allegedly shot and killed another man in self-defense at a townhome near Georgia State University late Sunday night.

Officers got a call about shots fired at the Summerhill by Hedgewood homes on Fraser Street around 9:30 p.m. The area is just east of Center Parc Stadium.

When they arrived, they found a man dead inside the home, police told The Atlanta Journal-Constitution. The Fulton County Medical Examiner’s Office identified him as Traquon Grubbs, 23.

The alleged shooter told Channel 2 Action News at the scene that he and his roommate were watching football with a friend just before the shooting. He believes that, at some point, the friend told two other men to knock on the door and pull a gun on the residents.

“I told them to leave,” the man told Channel 2. He did not want to be identified.

“They left with no contest, (but) I turned around, (and) there was a barrel of a gun to my face,” he added.

The man said his roommate then wrestled the intruders to the ground, but the barrel was still pointed at his face.

“They (the intruder and roommate) separated, and I opened fire in self-defense,” he told the news station. “The (suspect) had the gun in his hand and everything.”

Police have not released any additional details.
