A 20-year-old Payson woman died in a traffic crash Wednesday morning in Wyoming.

Tiffany and Sean Anderson, 20 and 19, were traveling east on Interstate 80 near Rawlins when Sean Anderson drove their Toyota Tundra off the right side of the road, hitting a delineator post. After an overcorrection, the truck rolled a number of times before coming to a stop on its top, according to a news release from the Wyoming Highway Patrol.

Tiffany Anderson was lying asleep in the backseat when the crash occurred and was not wearing a seat belt. She was ejected from the pickup and died at the scene.

Sean Anderson was hospitalized.

Investigators believe speed was a factor.
