An accident Tuesday morning on Interstate 29 in northwest Iowa’s Monona County has claimed the life of a man from South Dakota. The Iowa State Patrol reports a tow truck with its warning lights on was parked partially in the left lane of I-29 southbound at the 106.35-mile marker, with the operator working to remove a vehicle that had earlier entered median.

For reasons unknown, a 2010 Dodge pickup driven by 50-year old Darwin Knutson, of Webster, South Dakota, failed to move over, slow down or take evasive action for the tow truck, as required by Iowa law. The pickup, which was traveling in the left lane, struck the tow truck on the right rear side. The accident happened at around 6:24-a.m., Tuesday. After the collision, the pickup went off the road to the right and into a farm field.

Knutson, who was wearing a seat belt, was transported to a hospital in Onawa, where he died from injuries suffered in the crash. The operator of the tow truck was not injured.
