Richard Koch, 60, of Maplewood, Minnesota, was last seen June 27, 1989. He left home that day planning to travel to Bemidji with an acquaintance but was never heard from again. At the time he was 5 feet 10 inches, 180 pounds, with white hair and blue eyes, and was last seen wearing a dark blue shirt and dark blue slacks.

The Maplewood Police Department has the case open but has released few details about the circumstances of his disappearance. His case appears in multiple missing persons databases and, despite long-running interest and speculation that foul play may have been involved, no definitive evidence or significant leads have been reported.

Anyone who knew Richard, his travel plans that day, or the acquaintance he intended to travel with is asked to contact law enforcement with information.
