Fifty-one years after Jimmy Hoffa vanished, his family says it still wants the case solved and continues to seek answers about his disappearance. The anniversary renews attention on one of America’s most enduring unsolved mysteries, involving the former president of the International Brotherhood of Teamsters and long-standing allegations of organised-crime involvement.

Hoffa disappeared in 1975 and was never found. His son, James P. Hoffa, a former five-term Teamsters president, told Fox News that the family remains determined to learn what happened, despite decades of investigations, reported leads and unsuccessful searches.
