The Wyoming Highway Patrol reports that three people died in traffic accidents in the state over the holiday weekend.

Terence Buckner, 45, of Columbiaville, Mich., died shortly before 8 a.m. Friday when the pickup truck he was riding in rolled over on Interstate 90, west of Sundance in Crook County.
