JEFFERSON, S.D. – A Brunsville, Iowa woman has been identified as the person who died Saturday in a two-vehicle crash south of Jefferson.


A 2008 Ford Econoline E350 Ambulance was southbound on Interstate 29 when the driver lost control. The vehicle crossed both lanes, went into the median and then entered the northbound lanes. The ambulance struck the back end of the semi-truck and trailer. The impact caused the semi-truck and trailer to roll onto its passenger side.


Tonya Bruscher, 29, was the passenger in the ambulance. She was not wearing a seat belt and was thrown from the vehicle. She was pronounced dead at the scene.


Jacob Smith, 22, of Sergeant Bluff, Iowa, was the ambulance driver. He was wearing a seat belt and suffered minor injuries. He was taken to a Sioux City, Iowa hospital.


Bruce Muehler, 62, of Campbell, MN was the driver of the semi-truck. He was wearing a seat belt and sustained minor injuries. He was not transported.


Interstate 29 in that area was closed to traffic for about eight hours, opening again at 11:20 a.m. Traffic was rerouted off of Exit Four through Jefferson and back onto the interstate at mile marker nine.


South Dakota Highway Patrol continues to investigate the crash. All information is only preliminary at this time.


The Highway Patrol is part of the South Dakota Department of Public Safety.
