Eugene Weeks was pronounced dead at the scene of the accident on South Carolina Highway 19 north, near South Carolina Highway 191.
Weeks was traveling north on a 1996 Harley Davidson motorcycle when he left the road, lost control of the motorcycle and slid more than 200 feet. His body came to rest in the northbound lane, where he was struck later by a white Monte Carlo driven by Keivea Moore of Edgefield, S.C. Moore said she did not see the body lying in the road.
It appeared that Weeks died of injuries suffered in the original crash, Carlton said.
An autopsy is scheduled for Monday in Newberry, S.C. Toxicology is pending. The crash is being investigated by the South Carolina Highway Patrol and the Aiken County Coroner's Office.
The fatality is the 16th in Aiken County this year, Carlton said.
