In late summer 2003 Brantford, Ontario, resident 43-year-old John Tucsok was last seen on September 5, 2003, and later reported missing. His vehicle turned up abandoned in the Niagara Falls area, a major border crossing into the United States, which prompted investigators to consider that he may have left the country. Authorities also looked into the possibility he travelled to western Canada.

The case is closely tied to 17-year-old Heather Moggy, missing from Sudbury since June 22, 2002. Tucsok and Moggy shared a post office box in Brantford that remained active until September 2003. A letter postmarked from Calgary was received, and Heather’s last known contact was a phone call to her family in October 2003 saying they might be heading to Moose Jaw, Saskatchewan.

Complicating the disappearance, Tucsok was out on bail and subject to a Canada-wide warrant on charges of sexual assault and sexual exploitation involving female youths; police considered him to be violent. The whereabouts of both Tucsok and Heather remain unknown. Did anyone in Brantford, Calgary, Moose Jaw or along the Niagara crossing see either of them in 2003?
