Tucker J. Kunz, 18, was riding in the back seat of a 2016 Lexus driven by a cousin when the car went off the road, went airborne and rolled on Interstate 84 near Snowville, Utah, Monday afternoon, Utah Highway Patrol reports.
Passersby stopped to help and got everyone out of the car before it caught fire, UHP Lt. Lee Perry said Tuesday. Kunz was unconscious when he was removed from the car and despite resuscitation efforts died on the way to a nearby hospital, Perry said.
The driver, 18-year-old Zachary Witnah, and passenger Shelly Witnah, 57, were taken to the Bear River Valley Hospital for treatment of multiple injuries, UHP reports. The Witnahs live in Highland, Utah.
Flames destroyed the Lexus and caught grass in the median on fire, UHP reports. The eastbound freeway was closed for 45 minutes until the fire was extinguished.
The Utah Highway Patrol is still investigating to determine what caused the accident, Perry said, adding that it doesn't appear that the car was traveling more than 5 mph over the speed limit when it went off the road.
