When Osage Beach firefighters pulled up to a burning eight-unit apartment building at 1182 Mace Road last night, flames were already showing through the roof. Osage Beach Fire Protection District Deputy Chief Terry Paul says the blaze apparently started in an occupied second story apartment unit in the rear of the building. He says everybody got out safely. The hot weather made firefighters’ work more difficult than usual, and Mid-County, Lake Ozark, Camdenton and Eldon firefighters rotated in to relieve the Osage Beach crews. The cause of the the fire is under investigation.
