A Casper man accused in a fatal crash last year entered his pleas in court.

Alex Tougher has pleaded not guilty to one charge of vehicular homicide and one charge of leaving the scene.

The charges stem from a roll-over crash which killed Lydia Pace.

Troopers say in the early morning hours of December 19th, Tougher was driving a Ford Explorer on the freeway ramp from the east-bound 20-26 bypass, to southbound I-25, when he lost control and rolled the Explorer down an embankment.

The patrol says that Tougher was going more than 80 miles per hour on the ramp, when he lost control.

Pace was pronounced dead on the scene, but the patrol wasn't notified of the crash until about six hours later, when Tougher and another passenger had already left the scene.

If convicted, Tougher faces up to twenty years in prison.

He remains at the Natrona County Detention Center on $250,000 dollars bond awaiting trial.
