Clarkston, GA — Police are investigating a deadly shooting that left one man dead and another critically injured outside an adult entertainment club early Saturday morning.

According to Clarkston police, officers responded around 3:55 a.m. to reports of shots fired at a club located at 1353 Brockett Road near U.S. 78. When they arrived, they found 31-year-old Gary Matthews of Lithonia dead at the scene. Officials say Matthews had been celebrating his birthday when the shooting occurred.

Investigators said Matthews and three others — two men and two women — were sitting inside a vehicle when two men got out of a Jeep and opened fire. One of the men in the vehicle was struck and taken to a nearby hospital with life-threatening injuries. Officers tried to stop the suspects as they fled, but the Jeep managed to get away. It was later found abandoned.

The DeKalb County Police Department assisted Clarkston officers at the scene, but the case is being handled by Clarkston police.

Authorities have not released a motive for the shooting and have not said whether the suspects and victims knew each other. No arrests have been made, and investigators are still working to determine what led to the gunfire.
