The Utah Highway Patrol has identified a man killed in an Iron County crash Friday night.

Troopers say William Wyman slid off Interstate 15 in a Toyota Tacoma just north of Cedar City. The highway was slick because of the snowstorm. The Tacoma rolled, and Wyman — who was not wearing a seat belt — was thrown from the truck, UHP reported.

Wyman, of Boulder, Colo., died at the scene. His age was not available.

A passenger in the vehicle also sustained non-life-threatening injuries.
