Patrolman Harold Klinkefus was killed in an automobile accident when his cruiser was struck by a tractor trailer on US 34 near Red Oak.

Another car attempted to turn left and the truck attempted to stop suddenly in order to avoid a collision. The truck jack-knifed and struck the side of Patrolman Klinkefus’ car, causing him to be ejected.

Patrolman Klinkefus had served with the Iowa State Patrol for six years.
