It's always intriguing to try to reconstruct the last day of Jimmy Hoffa's life. There are very few witnesses who can attest for his movements from the time he arrived at the Machus Red Fox to the time he was picked up. It is also very curious that Hoffa would have agreed to meet with someone, Tony Provenzano, who had openly threatened to kill him. This explains his nervousness when he was heading to the fateful meeting as reported by eyewitnesses and his wife Josephine. What is just as curious is why Hoffa apparently voluntarily got into a car with his eventual killers. From the early days of the investigation, the conventional wisdom had been that Chuckie O'Brien picked up Hoffa from the Machus Red Fox that day. But After nearly 50 years of very close scrutiny, it is almost certain that O'Brien was not at the Machus Red Fox that day and did not pick up Hoffa. The Argument for his exoneration is very complex but convincing.

Hoffa's close friends, associates and family all agreed that he would never have willingly gotten into a car with strangers or people he knew would harm him without fighting back. This was the rational behind implicating Obrien who was in fact seen near the restaurant that day on a few occasions. If it was not O’brien, his killers, who are most likely the mobsters who picked him up (it's unlikely the he would have been handed over to a different squad--risk of too many people involved) were people he knew and trusted.

In the Early months of the investigation, the FBI's leading theory was that that New Jersey Genovese mobsters had flown or driven to Detroit to assassinate Hoffa at the direction of Anthony Provenzano. While Tony Pro's involvement in the plot is certain, it seems unlikely that Detroit would have required a squad of out-of-state mobsters to do the deed. They were perfectly capable of handling Mr. Hoffa. While I do not completely exclude the possibility the Salvatore "Sally Bugs" Briguglio was there, I think this is unlikely (though he must have been aware of some details of the plot given his close relationship with Tony Pro). There was however an eyewitness that placed Mr. Briguglio at the Red Fox at around the time Hoffa was present but her testimony did not prove to be reliable as she identified him after she saw his picture in the papers as one of Hoffa's assassins. If Brugillio was a well-known Provenzano hitman, Hoffa would have been weary of getting into a vehicle with him. (Dan Moldea reported that Brugillio spent time in Detroit as Rolland MacMaster's bodyguard. Hoffa, who was keeping tabs on MacMaster, may have known this. This would make him more distrustful of Briguglio who worked for MacMaster, a man who was directly committing violence against the Hoffa faction faction in Detroit). The evidence for the presence and direct involvement of Pro's associates is therefore weak. So who picked up Hoffa?

We can be certain that is Vito Giacalone was directly involved in the abducting and murder of Hoffa given his lack of alibi that day, his criminal history and his role in setting up the meeting. Vito’s presence much is almost as certain as anything that is known about the Hoffa disappearance without direct physical knowledge. All the circumstantial evidence points to Vito's presence as part of the hit team. However, there where two other men in the car according to the reliable testimony of a truck driver who witnessed the kidnapping as he recognized Hoffa in the back passenger seat of the car.

It would have been clear to the Giacalone brothers who organized the hit that Hoffa's murder would be so high profile that the participants would need to be people that are trusted by the mob--made mobsters whose loyalty was beyond reproach. They could not risk anyone flipping. The other requirement to be in the hit team must have been friendship with the target, Hoffa. Make no mistake Hoffa was killed by a friend and associate. There are two mobsters that fit this category perfectly well: Peter "Bozzi" Vitale & Raffaele "Jimmy Q" Quasarano. Quasarano was a long-time Hoffa associate going back decades (Hoffa was questioned in front of a Senate committee on his association with Quasarano). Vitale himself was a close associate to Quasanao and Knew Hoffa. These two men, as high ranking members of the Detroit partnership, knew about the meeting. They were seen with Frank Fitzsimons in the days prior to the disappearance, likely briefing him about the details of the upcoming events. There is an unconfirmed report placing Vitale and Quasarano along with Joseph Zerelli and the Giacalone Brothers eating at a mob restaurant the weekend prior to the Hoffa's disappearance. In retrospect, these events along with Hoffa’s confirmed meetings with the Giacalone brothers in the weeks prior to His murder was used to slowly lure him into a false sense of security ahead of this contentious and dangerous meeting with a man who had threatened to kill him. Thus, though Hoffa may not have been expecting Quasarano and Vitale in the car, he would have felt comfortable with these men as they were aware of the meeting and they were his long-time associates. Vito's presence would have put Hoffa at ease as he was the co-organizer the meeting.

Quasarano's direct involvement makes sense because FBI informant(s) also reported that his trash incinerator company's facility was used to dispose of up to 10 murder victims. The fact the Hoffa's body has never turned up gives additional credence to the notion that, as per their customs, the Detroit LCN destroyed the body their murder victims. Quasarano was in charge of getting rid of Hoffa's remains likely after killing him with the help of the aforementioned associates who were present. Quasarano is cited in the Hoffex memo, written six months of the disappearance as "considered by sources to be involved in the actual murder of JRH, because of violent activities in the past." Furthermore, the candid confession of Tony “Tony Pal” Palazzolo in the 1990s as to his involvement give more credibility to Quasarano’s involvement since Tony Pal was a close associate of Quasarano and Vitale in the 1970s.

If it was possible to have a trail for every person said to have been in on killing Hoffa, they would need the world's biggest courtroom to fit all the defendants.

Seems interesting
Amazing after all these years more info/data coming out on this

Well, all of those suspects are listed in the Hoffex Memo, except for Tony Pal who only emerged as a l suspect within the last 30 years. So this is not just speculation.
