Donald Leonard Douma was 19 when he was last seen leaving his family home in Osnabruck Center, Ontario, on May 19, 1981. He rode away on a blue CCM bicycle and was described at the time as 6 feet tall and about 176 pounds. Known as an avid outdoorsman who sometimes hitchhiked, Donald had spoken about a desire to move out West, and his family initially held out hope he might have started a new life.

No communication followed his disappearance, and the prolonged silence turned that hope into lasting uncertainty. The Stormont Dundas and Glengarry detachment of the Ontario Provincial Police is the agency of record; the investigation remains open. The last confirmed image of him is of him riding off on the blue bicycle — the final known moment in a life that has since become a cold case.

If anyone knew Donald, saw him in the months after May 19, 1981, or has information about his travels or whereabouts, please share what is known.
