William Anthony McKinnon, 28, vanished while hiking on Church Mountain in Washington on February 14, 1993. He was with his roommate and two friends on a familiar path; the group had used it about three times before. At roughly 4,500 feet they encountered snow and William, uneasy about the conditions and the risk of falling, stayed behind while the others continued toward the meadows.

When the group returned to the spot where they had left him, William was gone. He was last seen wearing a sweater, blue jeans, a green jacket, and Converse tennis shoes. Friends searched immediately but as darkness fell they reported him to the Whatcom County Sheriff’s Office and a formal search and rescue operation scoured the mountain. No footprints, discarded clothing, sign of a struggle, or other clues were found.

The terrain and snowy conditions complicated searches, and despite continued efforts the trail grew cold. The case remains open. Did anyone hike Church Mountain around February 14, 1993, who might remember seeing William or unusual activity that day?
