Vital Vachon, 55, was last seen on May 1, 1973, leaving a bush camp in Lucas Township near Timmins, Ontario. Described as a Caucasian male, slender, about 5 feet 7 inches and 159 pounds, with brown hair and brown eyes, he vanished from a remote, densely forested area of lakes and rivers that complicated early search efforts.

Public details about why Vachon was at the bush camp, who he might have been with, or his state of mind that day have not been shared. Investigators conducted searches in the weeks after his disappearance, but the terrain made locating any trace difficult. Over the decades the case has gone cold, and few if any new leads are known.

Does anyone who lived or worked near Lucas Township in 1973 remember Vital Vachon or have information about his movements around May 1?
