A collision Thursday afternoon in Adams County between a semi-tractor and a passenger van has claimed the life of a Coon Rapids man. The Iowa State Patrol reports a 2013 Dodge Caravan driven by 64-year old Jerome Koester, of Coon Rapids, was at a stop sign near Highway 34 and Highway 148, when for reasons unknown, Koester failed to yield and entered Highway 34.

A westbound 2006 Peterbilt semi driven by 47-year old Travis Dukes, of Lenox, struck the van. Following the collision, the semi rolled onto its driver’s side. Koester died at the scene. The accident, which happened at around 1:20-p.m., remains under investigation.

The Patrol was assisted by Adams County EMS, along with Corning Fire and Rescue.
