Deputies found Edward Cousette dead around 1:15 a.m. in the rear of Trinity Manor Apartments on the 2300 block of Barton Chapel Road.
Residents said they heard six gun shots before deputies arrived.
A motive is unclear but Sheriff's Lt. Calvin Chew said there were eight investigators with the Major Case Squad working on the murder. No other details related to the murder were released.
John Harris' 82-year-old mother took cover in her bedroom closet when she heard shots ring out at the apartment complex near her house. Harris said the apartments are not well maintained and should be better lit to deter the drug dealers there.
"You've got a whole bunch of kids running around here. If there were lights and cameras, the dope boys wouldn't be out here," Harris said.
Cousette was not in the military but lived with his wife at Fort Gordon.
This is Augusta's 29th murder of the year.
