Denevious L. Thomas, 36, died after officer Dan McMullen attempted a traffic stop, GBI Assistant special agent in charge Mark Pro said Tuesday.
Pro said McMullen attempted the stop after seeing Thomas' vehicle weaving through the streets early Tuesday.
Pro says Thomas attempted to flee and crashed into a wall. "He then tried to get out of the car and flee and was Tasered by the officer," Pro said.
Pro said Thomas was able to get to his feet with McMullen's help and walk back to the police car, where he was placed in the rear seat.
When officers began interviewing a passenger in Thomas' car, Pro said, they were told something that prompted them to go back to the patrol car and check on Thomas.
Pro said Thomas appeared to be all right, but before paramedics responding to the crash arrived, Thomas died.
Dougherty County police called in the GBI, and the body has been taken to a crime lab for autopsy. The immediate cause of death remains a mystery, Pro said.
"It could be from a variety of things, but like I said, he was able to walk back to the car, and he appeared fine when officers checked on him. It looks like we'll have to wait for the autopsy," Pro said.
