TULSA, OK -- Tulsa Fire Department investigators are looking into the cause of a south Tulsa house fire in the 6000 block of East 110th Street.

A neighbor reported the fire early Sunday morning after waking up to see the two-story residence fully involved.

The neighbor told firefighters the home has been for sale for three years and was vacant.

The flames spread to both stories of the house, and Tulsa firefighters used a ladder-pipe truck to get the fire under control within about 30 minutes.

No one was injured in the fire.
