The victim, whose name was not immediately available, was described at a black male in his 20s, according to Richmond County Sheriffs Investigator Chris Langford.
Little information was available as deputies surveyed a crime scene that stretched from Deans Bridge Roads intersection with Milledgeville Road to Cherry Road.
One witness heard six shots and saw him running, Investigator Langford said. He ran up to her, asked for help and fell on the ground.
The victim was taken to the Medical College of Georgia Hospitals Emergency Room, Investigator Langford said.
Police said they had no suspects identified and were not yet sure where the shots originated.
