Tucson fire officials say firefighters put out an early morning fire in what turned out to be an unoccupied house after being alerted by a newspaper deliverer.
A total of nine units and 23 firefighters responded Thursday morning, controlling the fire within 12 minutes of the first unit's arrival.
The Fire Department says the cause of the fire is unknown.
Most of the fire damage was to a back bedroom and bathroom but the rest of the home sustained heavy smoke damage.
A search found nobody in the home, but the owners arrived and told firefighters that it's vacant.
