JACKSON, Wyo. (AP) — Investigators say they're looking for a white male between 40 and 50 years old who they believe started a devastating wildfire in Wyoming.

They say he's between 5 feet, 10 inches and 6 feet tall and weighs 185 to 200 pounds.

The Roosevelt Fire destroyed 55 homes as it burned 96 square miles in western Wyoming last September and October. Authorities believe a man started the blaze by failing to extinguish a warming fire.

They say the suspect had brown hair and a short beard and carried a hunting rifle and compound bow on a backpack.

The Jackson Hole News & Guide reports anyone with information that might help investigators may call the U.S. Forest Service at (208) 557-5852.
