A single-vehicle rollover crash north of Rawlins resulted in the death of a Utah resident on Tuesday evening, according to the Wyoming Highway Patrol.

Parish D.G. Hansen of Sunset, Utah, and Kristen M. Cooper of Salt Lake City were traveling in a car southbound on U.S. Highway 287 about 41.5 miles north of Rawlins, according to the news release from Patrol Sgt. David Wagener on Wednesday.

At 8:08 p.m., the car veered right off the highway, over-corrected to the left and crossed both lanes of the highway. The car tripped and rolled on the shoulder of the northbound lane.

Hansen, 27, and Cooper, 30, were not wearing their seat belts and were ejected from the car.

Hansen died at the scene.
Cooper was taken by air ambulance to the Wyoming Medical Center in Casper. Her condition was unknown at the time the news release was issued.
Investigators have yet to identify who was driving at the time of the crash. Investigators are looked at impaired driving and improper lane use as contributing factors in this crash.
Hansen is projected to be the 58th highway fatality in Wyoming for 2015 compared to 59 fatalities during the same time period last year.
