(KLZA)-Details have been released on a late Thursday night single-vehicle rollover crash in Richardson County that left four individuals with serious injuries.

The Richardson County Sheriff's Office, in a release, said the crash was reported around 10:00 on U.S. 159 Highway near 656 Avenue, east of Falls City.

Upon arrival at the scene and after initial investigation, the release says it was determined that a 2003 Ford Mustang driven by 20-year-old Mason Wurtele, of Falls City, was eastbound when it left the south edge of the roadway, over-corrected, and rolled multiple times before coming to rest in a field on the south side of the highway.

Three passengers, Kaden Romo of Falls City, as well as two juveniles, were also present in the vehicle.

As a result of the crash, two occupants were ejected from the vehicle.

Three occupants were transported by the Falls City Volunteer Ambulance Squad to Community Medical Center in Falls City. One occupant was transported by Hiawatha Town & Country Ambulance to Amberwell Hospital in Hiawatha.

All four occupants remained in serious but stable condition and were later transported to other medical facilities, one by ambulance and three by medical helicopter.

The Sheriff's Office says seat belts were not in use by any of the four occupants. The release adds speed, drugs, or alcohol were not found to be contributing factors in the crash.
