Mark Gerald Gibbons was last seen at his Calgary residence on February 1, 1991. His family reported him missing that day and he has not been seen or heard from since. At the time he disappeared he was described as a Caucasian male, 74 inches tall, about 220 pounds, with brown hair and brown eyes.

Distinctive features include scars on his left cheek and forehead and flexed deformities on both his left little finger and his left ring finger. The case file notes there were no immediate signs of foul play, no note, and no indication he intended to leave, but the circumstances remain unclear and the investigation is still open with the Calgary Police Service.

Does anyone have memories of Mark, was in Calgary in early 1991, or has information that could help resolve what happened to him?
