This undated photo provided by Linda Shaw shows Shaw's son David MacDermott, at about age 25, with a dog and the cat, in Waterloo, Ontario, Canada. MacDermott was last seen in 2002 at a gay nightclub in Kitchener, about a 90-minute drive from Toronto. Shaw says she doesn't have any reason to believe her son was a victim of alleged serial killer Bruce McArthur, but she runs to the phone each time it rings in hopes that it could bring news about him.
