Meanwhile according to wiki:

On June 16, 2006, the Detroit Free Press published in its entirety the so-called "Hoffex Memo", a 56-page report the FBI prepared for a January 1976 briefing on the case at FBI Headquarters in Washington, D.C. Although not claiming to conclusively establish the specifics of his disappearance, the memo indicates that law enforcement's belief is that Hoffa was murdered at the behest of organized crime figures who deemed his efforts to regain power within the Teamsters to be a threat to their control of the union's pension fund.<23> The FBI has called the report the definitive account of what agents believe happened to Hoffa.

Is this the general consensus?
