An early morning fire heavily damaged a home on State Road 159 near Riley in Vigo County. The Riley Fire Department says the home is owned by Emory Counterman and occupied by four adults, two of whom were sleeping in the room where the fire started. The pair was awakened by the smoke. Although there were no smoke detectors in the section of the home where the fire started, all escaped injury. Fire officials say the blaze was accidental and started near an air conditioning unit.
