Arlène Gagné, 35, disappeared from her Montreal home on July 10, 1989. She spoke to her husband that morning and said she planned to stay home, but when he returned later the house was empty and all of her personal belongings remained behind. Investigators noted she was 4 feet 10 inches tall, about 99 pounds, with blue eyes and brown hair, and that she may have recently dyed her hair blond.

The presence of untouched personal effects has been a central and unsettling detail in the case, prompting police and family to treat the disappearance as unexplained rather than a planned departure. Despite an investigation by the Service de police de la Ville de Montréal and public appeals, no definitive lead has been reported and the case remains unsolved.

Did anyone in Montreal in July 1989 recall seeing Arlène or anything unusual around her home that day?
