William Jacobs, 64, of Belair Road, died at Doctors Hospital about 9:30 p.m., said Columbia County Deputy Coroner Harriett Garrison. The cause of death appears to be blunt force trauma, but an autopsy will be conducted Friday at the Augusta Crime Lab, she said.
Mr. Jacobs and his wife were visiting friends on Roswell Drive in Martinez when he was struck.
The Columbia County Sheriffs Office is investigating the collision. Charges could be brought against the driver, the deputy coroner said.
