A 38-year-old Mound City, Kansas man is dead after rolling his pickup east of Rawlins Thursday night.

It happened near milepost 233 on Interstate 80 around 10:30 p.m.​

Wyoming Highway Patrol Sgt. Jeremy Beck says Christopher W. Otto was headed west when he lost control of his pickup in a construction zone crossover and rolled it.

Otto was not wearing his seat belt and died at the scene.

Beck says driver fatigue, speed and inattention are being investigated as possible contributing factors.

Otto is the 85th person to died on Wyoming's highways this year.
