What Happened in the Greene County Accident?

The collision occurred shortly before 1 p.m. on Saturday, October 17, 2026, at the intersection of J Avenue and 290th Street, approximately six miles north of Bagley, Iowa.

According to the Iowa State Patrol, a 2004 GMC Sierra pickup traveling north on J Avenue entered the intersection without stopping at a posted stop sign. The pickup, driven by 16-year-old Gavin Pederson, struck the driver’s side of a westbound 2022 Freightliner semitruck.

Alli was a passenger in the pickup. Both teenagers sustained life-threatening injuries and were airlifted to hospitals in Des Moines.

The semitruck entered a ditch and struck a utility pole. Its driver, 65-year-old Joseph Wiederin of Lake City, was transported to a hospital in Jefferson with injuries initially described as non-life-threatening.

The Iowa State Patrol later reported that Alli died from her injuries on October 28. The crash remained under investigation in the latest reports reviewed.

AC/GC School Community Responds

The collision affected students, families, teachers, and staff throughout the Adair-Casey/Guthrie Center school community.

A prayer vigil was organised at the high school football field shortly after the crash, bringing community members together to pray for Alli and Gavin and support their families.
