Firefighters also sensed heat on the second floor.

During the preliminary investigation, the fire was thought to be coming from the attic. There were no injuries in the blaze.

Division chief Doug Green said late Sunday morning that investigators were still trying to determine the cause of the fire and extent of the damage.
