Investigators are trying to figure out what caused a fire in a Tulsa home early Friday. It is the second fire at the home this week.
Just before 1:30 a.m., firefighters were called out to the structure in the 300 block of East Young.
They arrived to find the back side of the home on fire.
Firefighters say there was another fire in the front part of the vacant home early Tuesday.
They say no one was hurt in either fire.
Captain Stan May said investigators believe the second fire was "incendiary."
