Responding Deputies found an adult male, identified as 51-year-old Michael Greene, of Winterset, who had suffered life threatening injuries. Greene was eventually flown to a Des Moines hospital where he died from his injuries.

A preliminary investigation shows that Greene was northbound on US Hwy 169 when he struck another motorcycle that was also northbound and slowing down in front of him. The driver of the second motorcycle was identified as 68-year-old Debra Field, of Winterset. Field suffered no known injuries.

The crash comes just days after a separate fatal motorbike crash that occurred in the 600blk of N Cross St in St Charles on May 19, 2022. That crash claimed the life of 56-year-old Jon Vonfeldt , of St Charles. An investigation into that crash suggests mechanical failure caused the front tire to lock up and eject Vonfeldt from his bike which had a small motor.

Vonfeldt was also flown to a Des Moines hospital where he later died from his injuries.
