ODESSA - Odessa Fire Investigators say they now know what started a massive grassfire on the south side of the city on February 25th, 2008.
A lit cigarette.
That's the finding from a joint investigation by the U.S. Forest Service, the Texas Forest Service, and the Odessa Fire Marshal's Office.
Around 33-hundred acres of property were scorched in the fire.
Remarkably, no homes or buidlings were lost in that fire.
