Two people are dead after a two-vehicle crash Monday near Manderson in Big Horn County.

The Wyoming Highway Patrol says 52-year-old Ralph Trujillo and 53-year-old Bobbie Jo Leyva of Worland, Wyo., were traveling northbound on U.S. Highway 20 shortly after 3:00 p.m. Monday when Trujillo’s vehicle crossed the highway’s center line and struck the southbound tractor trailer of 28-year-old John Sanders of Ocilla, Ga.

Troopers found both Trujillo and Leyva dead at the scene. A highway patrol release indicates Sanders wasn't hospitalized.

Sgt. Stephen Townsend says troopers are still investigating the incident and have not found any contributing factors. Townsend also says toxicology results are pending.
