Statesboro fire officials still don't know the cause of a blaze Aug. 26 that destroyed a restaurant and damaged nearby businesses in downtown Statesboro. The state fire marshal's office is assisting in the investigation to help determine what started the fire that gutted South and Vine Public House, a restaurant at South Main and Vine streets, said Statesboro Fire Chief Tim Grams. The state fire marshal's office was called in after local fire investigators were unable to pin down the fire's cause.
