Ronald Lamar Wallin, 25, disappeared from the area of Upper Manitou Lake in the Kenora District of Northwestern Ontario on August 20, 1981. What he was doing at the lake, who he might have been with, what he was last seen wearing, and whether searches were conducted have not been preserved in accessible records.

More than four decades have passed since Ronald was last seen, and there are no readily available follow-ups or public details to fill the gaps in his last known movements. The case remains unresolved and effectively faded from public view without new records or testimony to clarify what happened.

Did anyone in the area in 1981 have contact with Ronald or remember sightings around Upper Manitou Lake on or near August 20?
