An Upton man died following a one-vehicle rollover at 6:54 pm on Friday, April 27, according to a statement from the Wyoming Highway Patrol.

According to a press release, the crash happened on southbound US southbound, near Upton, in Weston County. Wyoming Highway Patrol troopers were dispatched to the area for the one-vehicle rollover.

Jonathan Bayert, 61, has been identified as the deceased in the crash. WHP officials say that Bayert died after he was ejected from his 2003 Dodge Ram 2500 pickup truck.

Bayert was reportedly not wearing his seat belt.

Troopers believe the crash occurred as Bayert was traveling in his Dodge, southbound, and failed to negotiate a right-hand curve in the road. The Dodge crossed the northbound lane and existed the highway.

Bayert then overcorrected his steering to the right, causing the Dodge to re-enter the paved portion of the road. However, Bayert then overcorrected his steering to the left, causing the Dodge to enter a counter clockwise rotation.

The Dodge entered the northbound borrow ditch, went into a broadside slide, rolled two times and came to a rest on its wheels. Bayert was ejected during the roll.

Troopers are investigating driver inattention as a contributing factor in the crash.
