Kenneth Edward Tank, 28, was last seen leaving Ralph’s Corner Bar in Moorhead, Minnesota, on December 2, 1971, apparently intending to return home in Fargo, North Dakota, but he never arrived. NamUs and local missing-person listings describe him as a White male, 6 feet tall, about 165–185 pounds, with brown hair and hazel or green eyes. He was reported missing by his wife on December 6, 1971.

Witness accounts place him at the bar that night; the Charley Project notes harsh conditions—around 17 degrees Fahrenheit with 20 mph winds—and reports say no taxi drivers remembered picking him up. He was last seen wearing a dark green or gray suit, white shirt, thin tie, brown shoes and a three-quarter-length brown car coat with a black fur piece. The bar has since been demolished and there is no confirmed explanation for what happened after he left.

The Fargo Police Department is listed as the investigating agency and the case remains open in NamUs (MP23462). Anyone who knew Kenneth, saw him that night, or has information about his disappearance is asked to contact the Fargo Police Department at 701-235-4493.
