Police search warrants have revealed that substance use may have been a contributing factor, in a deadly single vehicle crash at Wyoming Medical Center.

Through search warrants filed in Natrona County Circuit Court, Casper Police Officers found a pipe with a burnt residue, that smelled of marijuana, inside the car, as well as a can of compressed air duster, which was found on the floor of the drivers side.

The incident happened in September, when a car crashed into the northeast corner of the Wyoming Medical Center building.

Twenty-seven year old Brandon Avery and 27-year old Amanda Strickland died as a result of injuries they sustained from the crash.

A juvenile female who was also involved in the crash, is still in the hospital in stable condition, but police say she is not well enough to talk to investigators.
