Patrick Smith, 33, died around 7:10 a.m. Saturday at Medical College of Georgia Hospital, according to Columbia County Coroner Vernon Collins.
His autopsy will be held at the Georgia Bureau of Investigation lab in Augusta on Monday.
The shooting occurred in the 600 block of Blanchard Road, where Smith was shot in the stomach and resident Philip Marshall, 44, was shot in the back.
Several shots were fired, said Columbia County sheriff’s Capt. Steve Morris, and Marshall was in serious condition Friday night.
Though the shooting occurred inside the home, Smith was found in a Chevrolet Suburban on the side of Blanchard Road. A handgun was recovered from the vehicle.
