Frederick Archibald Seymour, 66, was last seen outside his home in Kars, Ontario, at about 11:00 p.m. on August 26, 1976. A neighbour’s sighting that night is the final publicly documented moment placing him at a known location. He was described as a white male of medium build, about 5 feet 8 inches and 170 pounds, with grey hair and blue eyes, wearing dark green pants and a beige coat.

The case remains centered on that single late-night sighting outside his home; what happened after he was seen is not publicly recorded.

If anyone saw Frederick that night, or has memories or information about his movements around August 26, 1976, please come forward with what you know.
