A Casper woman involved in a deadly crash has changed her plea and has been sentenced.

Heather Christensen was sentenced to eight-to-twelve years at the Wyoming Women's Center in Lusk, after changing her plea to guilty on one charge of aggravated vehicular homicide.

She admitted being the driver of a vehicle, involved in a collision that killed Richard Condelario in November of last year.

According to investigators, the vehicle that Christensen and Condelario were in, was northbound on Wyoming Boulevard, when it crossed the center line, sideswiped another vehicle going in the opposite direction and then crashed head-on into a traffic light pole at 13th Street.

Christensen told police that not long before the incident, she and Condelario had inhaled some duster.

Police found at least two cans of duster on the scene.

Christensen was originally scheduled to change her plea, but then also requested that a judge proceed with sentencing, and the motion was granted.
