Philomena Sisson was 67 when she was last seen in the Duncan, British Columbia area on May 17, 1970. Her son, Harry Jack, reported her missing from his Boys Road residence on May 22. Philomena was a First Nations woman who sometimes used the surnames Jack, Peters, or Sisons; she had grey hair, brown eyes and a medium build.

Her life circumstances complicated the search. She struggled with alcoholism and occasionally went missing for days, and she also had dementia, a condition that could have left her disoriented and vulnerable. Investigators at the time found no indication of foul play, and the case has gone cold with no new leads.

Does anyone in the Duncan area remember seeing Philomena in May 1970 or have family knowledge about the names she used?
