I think that this was the Blue Earth County Sheriff in 1965 at the time of Dickie's disappearance. He was personally interested in the case and coordinated the large search effort which took place. He continued to personally search for Dickie after the official search failed to turn up any trace of him.
Is it possible that he had the original case file in his possession after leaving office?
