A Casper man has admitted to being the driver in a fatal vehicle rollover last year.

Twenty-six year old Alex Tougher has changed his plea to guilty on one count of aggravated vehicular homicide.

According to the Wyoming Highway Patrol, in December, Tougher was driving a Ford Explorer on the freeway ramp from the East-bound 20-26 bypass to South-bound I-25, when he lost control and rolled the vehicle down an embankment.

The incident ended up killing Lydia Pace, who was a passenger in the vehicle.

Troopers say that tougher was going more than 80 miles per hour, when he lost control.

Tougher admitted that he had been drinking with friends in the hours prior to the roll-over.

As part of a plea deal, prosecutors will seek no more than a seven-to-ten year prison sentence and dismissed a charge of leaving the scene.

Tougher is being held on two-hundred and fifty thousand dollars bond and will be sentenced at a later date.
