Arthur Joseph Roy was 81 when he left his North Bay, Ontario, home on foot on September 18, 1977, at about 2:00 p.m. He was reported to be living with mental illness and probable senility and had never disappeared before. The last confirmed sighting that day placed him walking along Highway 11, more than 10 miles from his residence and near the old North Bay Psychiatric Hospital, though he had no known connection to that institution.

At the time he went missing he was described as a white male, 5 feet 8 inches tall, 174 pounds, with grey hair and brown eyes. He wore glasses and false teeth and was last seen in an orange short-sleeved shirt, grey pants with black suspenders, a grey coat, a black hat, and black shoes. The North Bay Police Service opened an investigation under case number 77-7222; initial searches produced no clues and his whereabouts remain unknown.

If anyone had contact with Arthur, saw him that day, or remembers the Highway 11 area in September 1977, please share information that could help solve this cold case.
