SPANISH FORK — A Mount Pleasant woman died and two others were injured in a two-vehicle rollover accident on U.S. 89 Friday.

Rebecca Dorton, 36, of Mount Pleasant, was driving north near milepost 303 at 6:25 p.m. when her vehicle went over the rumble strips on the right side of the road. The Utah Highway Patrol reported that Dorton overcorrected, crossing into the southbound lane. Her vehicle struck the rear bumper of a vehicle and was then struck by a pickup truck.

Dorton's vehicle and the truck both rolled, and the truck came to rest upside down. Dorton was killed in the crash. She was not wearing a seat belt at the time of the collision, UHP troopers reported.

Her son, 1 ½-year-old Chance Morrell, sustained two broken collar bones and a broken leg. He was flown to Primary Children's Medical Center in critical condition. The driver of the pickup truck, Claudia Munford, 48, was hospitalized at Utah Valley Regional Medical Center with injuries that were reportedly not life threatening.
