Gavin Pederson Guthrie Center, Iowa, Crash: Student Seriously Injured in Greene County Collision

GUTHRIE CENTER, Iowa — Gavin Pederson, a 16-year-old student associated with Adair-Casey/Guthrie Center schools, was seriously injured in a two-vehicle collision in Greene County on Saturday, October 17, 2026, according to a report by Western Iowa Today citing the Iowa State Patrol.

The crash occurred at approximately 12:58 p.m. on J Avenue, south of 290th Street. Authorities reported that Pederson was driving a 2004 GMC pickup northbound when it failed to stop at a posted stop sign and collided with a westbound 2022 Freightliner semi-truck.

The impact sent the pickup spinning into a ditch on the southwest side of the road, and Pederson was ejected from the vehicle. A passenger in the pickup, identified as 15-year-old Alli Wiers, was also seriously injured. Both teenagers were transported to Methodist Hospital in Des Moines for treatment.

The semi-truck, driven by 65-year-old Joseph Wiederin of Lake City, entered a ditch on the northwest side of the road and struck a utility pole. Wiederin was taken to Greene County Medical Center in Jefferson with suspected minor injuries.

The collision prompted concern within the local school community because both injured teenagers were associated with Adair-Casey/Guthrie Center schools. However, the credible report reviewed does not state that Pederson or Wiers died.

Online headlines describing Pederson’s death therefore conflict with the available local reporting. Until authorities or the family issue a verified update, claims that the teenager has died should not be repeated as fact.

Further updates about the teenagers’ conditions may be provided by their families or relevant authorities. The available report focuses on the crash circumstances and the injuries sustained by those involved.
