The case is still active, but unless there is a deathbed confession or somesuch, the chances of solving it is not looking good since people with first hand knowledge are either already dead, or very old.
The FBI’s Detroit office on Wednesday said the Hoffa case “remains one of the most well-known missing person investigations in FBI history.”
“Regardless of the age of the case, the FBI Detroit Field Office remains committed to following all credible leads and is seeking information to assist in moving this case forward,” the agency said in a release. “The Hoffa investigation remains active, and our office continues to urge anyone with information to come forward.”
