On this day in 1975: Jimmy Hoffa disappears

Notorious crooked Teamsters union boss Jimmy Hoffa disappeared on this date in 1975. He was last seen in the parking lot of a suburban Detroit restaurant. When news broke the next day of Hoffa's disappearance--no one, including me, expected him to resurface alive.

Mafia influence was strong when Hoffa ran the Teamsters. The union's current president is his son, James P. Hoffa.

The elder Hoffa's presumed murder is still an open criminal case.
