Timothy Wilson was a passenger in a car that came under fire around 2:30 a.m. in the 1800 block of Williston Road, according to Aiken County sheriff's Capt. Troy Elwell.
Elwell said there were at least two gunmen who came out of the woods surrounding the house. Three weapons were used.
Wilson was taken to Medical College of Georgia Hospital, where he died at 4:45 p.m., said Aiken County Coroner Tim Carlton.
Two other victims in the shooting told investigators that they were there to do some recording when the gunmen attacked and shot their vehicle several times.
One victim had a weapon at the time of the incident. Elwell said forensics would show whether it had been fired.
Deputies heard gunfire coming from the woods when they arrived at the home, but they were unable to find the source.
Williston Road was closed for about three hours while deputies and the bloodhound team searched the area.
The gunmen's getaway car could be a green Honda Civic, according to authorities.
Elwell said late Friday evening that a motive was still being established by investigators.
The most recent homicides in Aiken County before Friday took place Aug. 11 when two women, ages 75 and 38, were suffocated and then burned after their deaths. Investigators have arrested Franklin Wright, 55, in connection with their deaths and the severe beating of Jennie Hope, a Richmond County shopkeeper.
There have been 29 homicides in Richmond County since the beginning of the year, the most recent taking place Sept. 18.
