Investigators Call Grass Fire That Burned 50 Acres 'Suspicious'

Fire crews race to put out a suspicious grassfire Tuesday evening.

As many as 50 acres burned near Highway 412 and the Creek Turnpike.

Firefighters from six departments responded, including Tulsa, Catoosa, Verdigris and Inola.

The fire didn't threaten any homes, but investigators believe it's suspicious, because it appeared the fire had been set in four separate places.
