Kenneth Edward Tank, 27, vanished after leaving Ralph’s Corner Bar in downtown Moorhead, Minnesota, on the night of December 2, 1970. He lived in Fargo, North Dakota, and would normally have had about a thirteen-minute drive home. Witnesses say he left the bar at approximately 11 p.m. in bitter weather—about 17 degrees Fahrenheit with strong winds—and no taxi drivers reported picking him up. His wife reported him missing on December 6, 1971, and the Fargo Police Department continues to list him as missing.

Tank was married in 1963 and had two children. He’d recently left his job as an insurance adjuster; his wife said he was disheartened by denying claims, while a family member later said the family had received threatening phone calls before his disappearance and that the calls stopped afterward. Human remains found near Ayr, North Dakota, in 2004–2005 were DNA-tested and ruled not to be his. He was declared legally dead in December 1977 so his then-wife could collect life insurance.

The circumstances of his leaving the bar and what happened after remain unknown. Does anyone have memories of that Moorhead area or knew Kenneth and his family in 1970–1971?
