The Sioux County Sheriff’s Office reports that about 2:40 PM, 58-year-old Mary Boeve of Hull was backing a 2010 Yamaha Grizzly four wheeler two miles north of Hull when the throttle apparently became stuck. The ATV over-turned, trapping Boeve underneath it. A passenger, 6-year-old Joseph Freeman of Sheldon was ejected from the vehicle.
Boeve received serious injuries. Freeman received minor injuries. Both were transported to the Hegg Memorial Hospital in Rock Valley by the Hull Ambulance.
Boeve was later airlifted to Avera McKennen Hospital in Sioux Falls.
The sheriff’s office was assisted by Hull Ambulance and Fire units.
