(Osceola, Iowa) – The Iowa State Patrol says a driver suspected of being impaired was one of two people injured in a collision Saturday afternoon in south central Iowa. The accident happened at around 2:25-p.m. on northbound Interstate 35, between Osceola and Van Wert, when a Dodge Caravan driven by 41-year-old Natasha Marie Lyons, of Leon (IA), collided with a Semi tractor-trailer that had been stopped on the shoulder of the road with its hazard lights on due to mechanical issues, and was preparing to re-enter I-35.

When Lyons failed to move-over, her van sideswiped the semi before it crossed both northbound lanes and came to rest in the median. The semi remained on the shoulder of the road.  Lyons, and a passenger in her vehicle, 11-year-old Sawyer Whitt, of Leon, were injured and flown by helicopter to the hospital. The child was transported to Blank Children’s Hospital. Natasha Lyons was transported to Iowa Methodist Hospital. Both had been wearing their seat belts. The 47-year-old driver of the semi, who was from St. Louis, MO., was not injured.

Northbound I-35 was closed for about 4-hours following the crash. The Patrol says a drug investigation into the crash is underway.
