Police and fire investigators are trying to determine what caused a fire to break out in a home at 2214 Washington Ave. Wednesday afternoon. Firefighters were called to the scene at 3:30 p.m. after a resident on the second floor reported the carpet was on fire. When crews arrived a piece of burned carpet was lying outside the residence, already extinguished. They entered the building to make sure the fire had not spread and to make sure all the residents were out. The fire was confined to the second floor.
