In the early autumn of 1973, a 31-year-old woman named Marguerite Elizabeth Cardwell vanished from her life in Calgary, Alberta, leaving behind a perplexing and enduring mystery. On September 10th of that year, she communicated to a friend her intention to travel, possibly to Edmonton, Alberta, or as far as Vancouver, British Columbia. This was the last known time anyone would hear from her.
A few days prior to this, Marguerite, a mother and a woman of varied professional experiences including secretarial work and possessing a pilot's license, had made a purchase that would later cast a somber shadow over her disappearance: a. 303 calibre hunting rifle. The days immediately following her last contact are not precisely documented, adding to the ambiguity of her case.
The unsettling discovery that solidified her status as a missing person came between the 16th and 18th of September. Marguerite's vehicle was found abandoned on a desolate stretch of road along the Number 1 Highway, about 12 miles east of Canmore, Alberta, in an area known as Dead Man's Flats. Inside the car, investigators found her personal belongings, including her purse and keys, seemingly undisturbed. This discovery prompted an immediate search of the surrounding rugged terrain. Despite a two-day effort by numerous RCMP officers, no trace of Marguerite or the rifle she had purchased was found. The initial theory leaned towards the possibility that she had taken her own life, a belief bolstered by information that she had previously attempted suicide.
However, the narrative of a straightforward suicide was complicated by other emerging details. Her roommate later recounted a troubling incident on the night Marguerite disappeared, stating that a man had been at their suite's door, yelling at her. This information introduced the possibility of foul play, a prospect that her daughter would later advocate for. Years after her disappearance, her daughter gained access to the extensive police file on her mother's case and has continued to seek answers. The official investigation has seen periods of inactivity and has been re-opened, with Marguerite's daughter providing a DNA sample in the hope of a future match. The case of Marguerite Elizabeth Cardwell is an overview of a story with conflicting possibilities; a woman who may have succumbed to her personal struggles in a remote and lonely place, or a woman who may have met with an unknown individual with harmful intentions. Without new evidence or the discovery of her remains, the definitive story of what happened to her after she was last seen in September of 1973 remains untold, leaving a void of unanswered questions for her family.Last Seen: Sep 16, 1973
