The cause of Saturday’s fire at the Camp Aldrich Conference Center Dining Hall hasn’t been determined, Claflin Fire Chief Doug Hubbard said Monday.“I can safely say it was accidental,” Hubbard said. Other than that, he is waiting for an official report from the state fire marshal’s office.The building was not in use at the time and no one was injured. The fire was reported with a call to 911 just after 5:30 a.m. Smoke and flames were visible from the building.
