Alphonse Brochu, 46, vanished from Ottawa on January 25, 1967 after leaving home to deliver documents to a government agency. He was last seen wearing black boots with rubber on the toes, black pants, and a blue long-sleeved sweater. His car was found abandoned that same day on the Champlain Bridge, which links Ottawa to Gatineau, but there was no sign of him.

Family members told authorities he had been experiencing a period of depression before he disappeared. An initial search and investigation produced no conclusive answers, and no definitive explanation for his disappearance has emerged. Few details beyond the morning he went missing are known.

Did anyone in the area at the time have contact with Brochu or notice anything unusual on the Champlain Bridge that day?
