Wilfred David Bruder, known to some as Wolf, was 50 when he was last seen in Guelph, Ontario on February 28, 2004. Witnesses reported him using a payphone at Willow West Mall that day; he never returned to contact family or friends.

At the time he disappeared he was described as a white male about 5 feet 5 inches, medium build, with short brown hair, brown eyes, a moustache and partial balding. A distinctive detail: the ring finger on his left hand was missing. The Guelph Police Service investigated and made periodic public appeals, but no trace of him was ever found.

On July 19, 2011, Bruder was legally declared deceased. The circumstances of his disappearance remain unresolved and have left family and the community without answers.

If anyone saw Wilfred Bruder around Willow West Mall on February 28, 2004, or has information about his movements that day, please come forward.
