1. Jimmy Hoffa was an American Labor Union Leader, who was also president of the teamsters from 1958 to 1971. 

2. In 2006, "Hoffex Memo" was published, 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. 

3. Law enforcement found that President Nixon was a part of getting Hoffa out of prison under whichever circumstances that Frank Fitzsimons wanted to happen to him. They also found numerous documents of the pension fund increase in the number of loans after Hoffa was sent to prison. 

4. Sheeran told his lawyer that he was the one that killed Hoffa. He said he picked Hoffa up from the restaurant that he vanished from, told him they were going to a meeting at a house. Whenever they got the house, Sheeran followed Hoffa inside, and when Hoffa realized there was no meeting he passed by Sheeran, Sheeran shot in twice in the back of the head. The questions/issues that we’re said about Sheeran’s story was that he was a drunk, and it was very questionable because they we’re good friends, and “why would Sheeran, end a 20 year relationship like that?” They also said that because he never confessed under oath, so there’s no definite answer. 

5. Hoffa’s friend was a hitman for one of the bosses of the mob, and Hoffa also was at one point a hitman himself. He was in on all of the money that went and came from the casinos in Las Vegas. 

6. It pretty much ruined his relationship with the mob. Everybody in the mob that he had some sort of connection with turned against him, and was in on the death/kidnapping of him.
