A house fire on Monday is being investigated by the Danville Fire Department. When firefighters arrived at 17 Michigan Avenue they found fire on one side of the building and heavy smoke through the roof. Entry to the house was blocked, so they fought the fire from the exterior until entry was gained through a window. The home was unoccupied and had no utility services. Damage is estimated to be $10,000 to the structure and $3,000 to the contents.
