RAWLINS, Wyo. (AP) — Authorities say one person was killed and another was injured in a single-vehicle rollover accident just west of Rawlins.

The Wyoming Highway Patrol says 19-year-old Sean M. Anderson, of American Fork, Utah, was headed east on Interstate 80 when his pickup went off the side of the road at about 7:20 a.m. Wednesday. Anderson lost control of the vehicle, which rolled several times.

His passenger, 20-year-old Tiffany J. Anderson, of Payson, Utah, was sleeping in the back seat at the time of the crash. She was ejected from the truck and pronounced dead at the scene.

Investigators believe excessive speed played a role in the crash.
