Jean Jacques Sirois was 33 when he disappeared from Montreal’s Rosemont district sometime between September 3 and October 3, 1978. The last confirmed sighting places him in Rosemont and his family has had no contact since. Law enforcement records show the Service de police de la Ville de Montréal has kept his file active.

At the time he went missing he was described as five feet seven inches, slender, about 115 pounds, with blond hair, green eyes and a birthmark on his right arm. He wore a dental prosthesis on his lower teeth. His clothing that day was recorded as a beige shirt, brown pants and a brown windbreaker, and he wore a gold ring set with a rectangular cubic zirconia.

Few public details are available about the circumstances of his disappearance and the case remains unresolved. If anyone knew Jean Jacques, saw him in Rosemont in September 1978, or has information that could help, please come forward.
