Two people are dead and a commercial truck driver is charged with vehicular homicide after a crash south of Laramie on 287 Thursday night.

Robert Wight, 57, and Dawn Wight, 46, of Sandy, Utah were killed after their minivan was hit head-on at 11 p.m. Thursday, about 13 miles south of Laramie.

The Wights were southbound in a 2005 Chevrolet Uplander when, near milepost 413, a commercial truck towing a trailer driven by 58-year-old Charles Gibson of Midwest City, Okla. drifted into the southbound lane and hit the van head-on.  The commercial truck caught fire after the crash.

Two boys who were passengers in the van were taken to hospitals in Laramie and Denver, respectively.

Gibson was wearing his seatbelt and was not hurt. He was arrested and charged with vehicular homicide, according to a Wyoming Highway Patrol news release.

Troopers are investigating driver fatigue as the contributing factor in the crash.
