Details of Disappearance Harder was last seen in Idaho County, Idaho on April 23, 1978, his 33rd birthday. He had been taking care of a property in the Burgdorf area owned by a local couple. He was known as a loner and an eccentric, so he wasn't reported missing for ten days.
Although a search team was assembled, the weather was bad and searchers didn't know where to begin looking. Search efforts continued sporadically through the summer of 1978, but they never returned up anything. Little information is available in Harder's case; it remains unsolved.
