Alan Leroy Carl was 29 when he vanished from Duluth, Minnesota, on September 20, 1979. He is described as a white male, 5 feet 6 inches tall, about 140 pounds, with black hair and brown eyes. A history of alcoholism is noted and may have been a factor in his disappearance, but few details exist about his last known movements or the circumstances that day.

No personal effects, clothing, or jewelry have ever been linked to him. At the time investigators noted the absence of dental records and fingerprints, which limited identification options; his DNA is on file but has not produced any matches. The case was entered into NamUs and the NCIC and remains open with the St. Louis County Sheriff’s Office.

Anyone who knew Alan, saw him in Duluth around September 20, 1979, or has information that could help should contact the investigating agency.
