A Casper woman has entered a plea in a case where she was involved in a deadly vehicle collision.

According to prosecutors, on November 14th,  Casper police responded to a two-vehicle collision at the intersection of 13th and Wyoming Boulevard.

Initial reports say 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.

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

Police found at least 2 cans of duster on the scene.

Christensen remains jailed at the Natrona County Detention Center on fifty-thousand dollars bond, and is now awaiting trial.
