Marilyn Ann Byskal was 18 when she disappeared from Manitoba in the summer of 1974. Some records list her last confirmed sighting as June 20, 1974, but the exact date is unclear. Authorities have long suspected foul play, yet no body has ever been recovered and no charges have been laid.

The circumstances of Marilyn’s final days remain largely unknown to the public. Investigators have faced the central obstacle of a missing body, which has limited what could be established or prosecuted. Over the decades the trail has run cold and the family has not received closure.
