Details About Marguerite’s Case: Marguerite was last seen in Canmore, Alberta on September 16, 1973.
On September 18, 1973, her abandoned vehicle was found on No. 1 Highway, 12 miles east of Canmore, on a deserted road near Dead Man’s Flats. Her car was found with all of her personal belongings and keys in it. Investigators believed that she had driven out to the deserted road in the middle of the night and shot herself with a rifle she had purchased. After a two-day search of the area, her body was never located. She has never been heard from again, and not even a gun was found in the area. It is known that she had purchased a .303 rifle on September 10, 1973.
Marguerite was divorced and had been employed at various jobs in Calgary, Alberta. In 1993, twenty years after Marguerite disappeared, her daughter Shelley Sawatzky received a box of unclaimed belongings from the rooming house her mother managed in Calgary. The box was filled with photographs, employment forms and other personal records. It contained Marguerite’s Petroleum Ski Club card, the flying license she earned while living in Montreal, and T4 forms showing proof of her employment at various law firms and oil & gas companies.
A woman who lived in the same rooming house as Marguerite stated that on the night that Marguerite went missing, there had been a man at the door of Marguerite’s suite, yelling at her. That was the last night she was heard from.
