A 74-year-old Ogden man died Saturday in a farm accident near Pilot Mound in Boone County. Reportedly, Richard Shaw and his son, 54-year-old Michael Shaw of Ogden, were spreading anhydrous ammonia on a farm field when an anhydrous tank hose broke off causing a cloud of toxic gas to envelop the tractor.
Michael Shaw jumped onto the tractor, climbed inside in trying to drive the tractor out of the cloud. Richard Shaw was pronounced dead at the scene while his son was airlifted to a Des Moines hospital for medical attention and was later released.
The investigation is continuing.
