Dean Curtis Mortensen was a 19-year-old first-year science student at the University of Alberta’s St. Joseph’s College when he disappeared in Edmonton in the early hours after midnight on January 24, 1992. He had been at a campus pub, The Ship, then walked toward his residence. Friends who had been with him returned to the pub for a forgotten item; Dean continued the short distance alone and never returned.

Dean was described as responsible and diligent; the next day his bed remained made and undisturbed, and his bank accounts with more than $3,000 were untouched. He was last seen wearing faded blue jeans, Nike running shoes, a dark blue St. Joe’s Rangers hockey jersey and a Grande Cache Bantam Elks Hockey jacket bearing his name and position. About one to two weeks later a librarian found his dark blue St. Joe’s Rangers baseball cap in a backyard near the High Level Bridge, several kilometres from campus.

Theories have included accident, suicide and foul play, but no evidence has resolved what happened. If anyone knew Dean, saw him that night, or can place his cap near the bridge, please come forward with information.
