An 82-year-old Wyoming man is dead following a single-vehicle rollover near Hawk Springs.

The Wyoming Highway Patrol says Walter Bradley was headed south on U.S. Highway 85 around 3:30 p.m. Saturday when he lost control of his pickup and rolled it.

Bradley, who was not wearing his seat belt, was thrown from the pickup and died at the scene.

The Patrol says it was clear and road conditions were dry at the time of the crash.  A possible medical condition and equipment failure/issue are being investigated as contributing factors.
