The driver of the Jeep was treated on scene. The passenger of the Jeep was transported to a local area hospital with minor injuries. The 31-year-old male passenger of the Taurus had serious but non-life threatening injuries. The driver of the Ford Taurus, a 19-year-old female, was extricated before being transported by air ambulance in critical condition. On April 21, 2021 at approximately 0240 hours, Troopers learned that the 19-year-old driver of the Taurus, Gwendolyn Doner, of Casper WY, passed away due to injuries sustained in the original crash.

Ms. Doner’s Family requested that the below picture of her be given to members of the media and wanted the public to know that a vigil will be held in her honor at the Murray City Park on April 22nd, 2021 at 8 pm.
