A fire destroyed a house early Thursday morning. There were no reports of injuries. The house was unoccupied at the time, the Lebanon Fire District said. A passerby called 911 at 3:20 a.m. to report the fire. The first crews on scene found heavy fire and thick black smoke coming from the home. "Crews found heavy fire pushing in from the west side. Heavy smoke coming out of the attic space," said Jason Bolen with the Lebanon Fire District. "Indicated to them that they had a really well-seeded, well-burning fire." Firefighters worked the fire throughout the morning. Investigators were unable to determine the cause of the fire.
