After a series of arsons, Lebanon firefighters, police and the State Fire Marshal’s Office are hoping you may be able to help them find whoever’s behind fires at four vacant homes. The most recent fires were Sunday morning around 5a.m. Lebanon Fire Chief Sam Schneider says with all of the homes empty when they burned, they rules out human accident. Schneider says it’s not clear if the fires are connected. Anyone with information can call the Lebanon Police Department, Lebanon Fire Department or the State’s Arson Hotline at 1-800-392-7766.
