Chris Michael Jennings was 16 when he was last seen in Kootenai County, Idaho, on September 7, 1980. He had spent the day at the North Idaho State Fair participating in 4-H and showing animals, and was expected home afterward to feed animals and later attend a party. He never returned and his family lost contact.

Early on there was speculation Chris might have run away amid reported parental arguments, but that theory weakened as time passed without any word. Rumors also circulated about a possible late-night car accident — witnesses claimed seeing a wrecked Ford Mustang with blood inside — but law enforcement could not confirm those accounts. Other theories range from a hidden accidental death at a party to voluntary disappearance; several leads were followed but nothing substantial has emerged.

Anyone who knew Chris, attended the fair that day, or has information about a Mustang or a party in the area on September 7, 1980, is asked to come forward.
