Circumstances of Disappearance
Marguerite Elizabeth Cardwell Peterson 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 she had driven out to the deserted road in the middle of the night and shot herself with a rifle she had purchased; however, after a two-day search of the area her body has never been found, 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 employed at various jobs in Calgary, Alberta. Papers that her daughter has with her T4's all indicate she was working at law firms, oil & gas firms as a secretary. She had a pilot's license from when she lived in Montreal.

A roommate stated that there had been a man at the door of Marguerite's suite, yelling at her the last night she was heard from.
