Edward Joseph Arcand was 27 when he left his home in Coleman, Alberta, on June 8, 1975, driving a 1969 Ford Falcon station wagon and was never seen again. He was described as 5 feet 8 inches, 139 pounds, medium build, with short black hair and brown eyes; at the time he wore a red shirt, blue denim jeans and a blue denim jacket. A week later, around June 15, his station wagon was found abandoned about 80 kilometres north of Coleman on Highway 940, a remote forestry road, with no sign of him, no obvious vehicle breakdown and no sign of a struggle.

Distinguishing features included a hernia scar on his lower abdomen and several missing teeth with some temporary fillings. Investigators later compared his records to an unidentified man recovered from a septic tank near Tofield in 1977 but dental records did not match and he was ruled out.

What information might help explain why Arcand’s car was left on that remote road, or where he went after June 8?
