Three Overnight Tulsa Fires Called Arson

Tulsa firefighters were called to three fires within a three-hour span overnight Wednesday. Investigators are calling all three cases of arson. 

The first fire took place around 10:15 p.m. at a duplex near 41st and 129th East Ave. Investigators say no one was living in the home at the time. They also said the fire was started in multiple areas within the house.

An hour later, an empty home was set on fire near 56th Street North and Martin Luther King Boulevard. 

Then just before 1 a.m., firefighters were called to a home near I-44 and Peoria - but they say no one was home. That fire started in the kitchen, investigators said.

We're told the residents are on vacation.

Stan May, Tulsa Fire Department, said all three fires were deliberately set.
