Salvatore Briguglio’s murder, as recounted by Frank Sheeran, was a carefully arranged shooting that also deepened the uncertainty surrounding the disappearance of James R. Hoffa. Briguglio had been under federal scrutiny and had spoken privately with authors about the Hoffa case; after he was killed, questions about what he knew, whether he had tried to cooperate, and why he became a target remained unresolved.

Background and the Killing

Briguglio entered the story as one of the men investigators suspected in the Hoffa disappearance. A page-three list in the HOFFEX file named him alongside Anthony Provenzano, the Andretta brothers, Gabriel Briguglio, Sheeran, and Russell Bufalino. With Tony Giacalone and Chuckie O’Brien added, the FBI’s working group comprised nine suspects. The list did not establish what any one man had done, but it concentrated the investigation on a small circle whose members had connections to the Teamsters and to one another.

The book also places Briguglio within a broader network that predated Hoffa’s disappearance. Sheeran describes Bufalino as a close friend and recalls driving him to Apalachin in 1957, where a gathering of gangsters was raided. He later drove with Bufalino to meetings at Joe Sonken’s Gold Coast Lounge in Hollywood, Florida, where figures from different parts of the country met, including Santo Trafficante and Carlos Marcello. That account supplies context for the cross-regional relationships around the people later named in the Hoffa investigation; it does not, by itself, prove a connection between those meetings and Briguglio’s death.

On August 4, 1975, five days after Hoffa disappeared, the FBI noted a meeting at the Vesuvio Restaurant in New York City attended by Anthony Salerno, Bufalino, Sheeran, Anthony Provenzano, and Briguglio. Sheeran later described the meeting as a report to Salerno on how the disappearance had been carried out and on whether any loose ends remained. In his account, the gathering concerned an operation that required Detroit’s sanction, while New York had neither authorized nor opposed it. The meeting is therefore presented as part of Sheeran’s claimed account of the disappearance, not as an independently established explanation of Briguglio’s later murder.

Sheeran’s account of the killing shifts from the broad suspicions surrounding the case to a specific street encounter. He says he and John Francis were told where to be and carried .38-caliber pistols tucked behind their backs. By then, Sheeran says, he trusted Francis to work with him anywhere. On March 21, 1978, Briguglio was walking alone from the Andrea Doria Social Club, a block from Umberto’s seafood restaurant in Little Italy, Manhattan. Sheeran says he approached and greeted him; Briguglio returned the greeting, then looked toward Francis, whom he did not know. As Briguglio turned to look, Sheeran says, he was shot twice in the head. Francis fired about three additional shots, which Sheeran describes as intended to make the scene sound like a shootout and frighten off anyone watching from nearby.

The account describes an escape plan as well as the shooting: a waiting car, arrangements to remove the guns, and backup vehicles positioned to interfere with FBI cars if necessary. Sheeran’s emphasis on timing and support makes the killing sound organized in advance, while his narration supplies no account of how those arrangements were made or who issued the instructions. The contrast between the precise details he claims to remember and the unanswered questions about the operation is central to the episode.

Briguglio as a Possible Witness

The shooting did not settle what Salvatore Briguglio knew about the Hoffa disappearance. Sheeran says he understood from experience that prosecutors seeking a deal would first require an offer of proof: a prospective witness had to outline what he could tell authorities before they could judge whether the information justified an agreement. In his telling, Briguglio seemed from early in the investigation to have something he wanted to disclose. That impression, however, is not the same as evidence that Briguglio had made a deal or identified anyone involved.

A Michigan state police detective, Koenig, watched the Andretta brothers and Briguglio brothers during the pauses between lineups before a Detroit grand jury in 1976. Koenig later recalled that Briguglio’s mind seemed troubled and that he was having difficulty coping; the investigators agreed to focus on him. The detail makes Briguglio’s apparent distress part of the record of the inquiry, but it does not establish its cause. The pressure could be read alongside the possibility that he knew more than he had disclosed, without resolving whether he intended to cooperate.

In 1977, Briguglio spoke privately with Steven Brill, the author of The Teamsters, under an agreement that Brill would not reveal their conversations. Brill later characterized the discussions as rambling and said they touched on the murder only occasionally. When Brill raised relatively minor aspects of the crime, Briguglio, according to the published account, sometimes confirmed them with a nod, but offered no elaboration and disclosed nothing sufficient to implicate anyone other than possibly himself. The guardedness of these exchanges leaves a narrow, suggestive trace: Briguglio did not simply deny all knowledge, yet the account does not show him supplying a usable confession or naming an accomplice.

Only days before his death, Briguglio also gave Dan Moldea, author of The Hoffa Wars, a recorded interview. Moldea described him as worn and tired under what he called enormous federal pressure. Briguglio said, “I’ve got no regrets, except for getting involved in this mess with the government. If they want you, you’re theirs. I have no aspirations any more; I’ve gone as far as I can in this union. There’s nothing left.” The words convey resignation and anxiety about government attention, but do not specify what he had told investigators—or whether he had told them anything. The timing gives the interview an ominous force in retrospect, without turning its ambiguities into proof of cooperation.

Sheeran raises the possibility that Briguglio had disclosed as much of the plot as he knew, and asks whether the Federal Bureau of Investigation might then have left him at liberty in hopes of obtaining an admission from a suspected killer on a wire. These remain questions in the narrative, not established findings. The book offers no confirmed account of an agreement, a recording made through Briguglio, or what information federal agents may have received from him. His private conversations, visible strain, and final interview therefore sharpen the mystery of his position in the case rather than resolve it.

Competing Explanations and the Record

The circumstances around the killing invited a labor-power explanation as well as the possibility of silencing a witness. At the time, Tony Provenzano was on trial over an alleged $300,000 kickback on a $2.3 million loan to the Woodstock Hotel, financed from the cash reserve of his union local. A newspaper reporter described Local 560 as a cash register. Victor Riesel, the labor reporter blinded in an acid attack twenty years earlier, reported that Provenzano planned to run for president of the International in 1981, when Fitzsimmons was expected to retire, and needed the popular Hoffa out of the way to improve his prospects. Riesel drew a parallel with the earlier removal of Anthony “Three Fingers” Castellito, another union figure whose displacement had served Provenzano’s effort to consolidate power, and said Briguglio had been used in both episodes. These were reported theories about motive, not a demonstrated account of who ordered Briguglio’s death.

The book questions how authorities and newspapers framed the case immediately after the murder. A New York Post account attributed the killing to a mob effort to take control of Local 560 and its pension and welfare funds, which could then support investments in legalized gambling in Atlantic City. The same report said investigators had not ruled out a role for Carmine Galante, then in jail. Sheeran asks why attention was directed away from Provenzano and the possibility of betrayal, and why investigators offered a jailed figure as an alternative suspect. The juxtaposition exposes the difference between a public explanation centered on control of union money and Sheeran’s suspicion that Briguglio’s knowledge or possible cooperation mattered; the evidence presented does not settle that dispute.

The larger investigation remained burdened by withheld records. After pressure from the news media and Hoffa’s children, who had pursued access to the FBI’s file through the U.S. Supreme Court without success, the FBI released a 349-page case summary in 2002. The Detroit Free Press reported that the disclosure followed a decade-long legal battle and marked the first public release of the Bureau’s own summary, but the document was heavily censored: names had been removed, witness-interview passages blacked out, and pages were missing. The partial release offered a public view of the investigation without supplying the missing account of what Briguglio knew, whether he had cooperated, or why he was killed.

The Clue of “Russ & Frank”

In the immediate aftermath of James R. Hoffa’s disappearance, the FBI found a yellow pad beside his phone in a summer cottage filled with members of his family, who were tearful and anxious. On it, Hoffa had written in pencil, “Russ & Frank.” The two names joined Russell Bufalino and Frank Sheeran in a private notation made by the missing man himself, before investigators publicly identified them as leading suspects.

The note carried its force through the trust it implied. Sheeran had remained close to Hoffa through legal ordeals and conflict with Bobby Kennedy, and was regarded as family; the family’s fear was that only someone close enough to be trusted could get near a cautious man alert to his enemies. The episode thus turns a small domestic object into a measure of the disappearance’s central betrayal: the names associated with Hoffa’s loyal allies became, in the family’s view and the investigation’s early focus, names attached to the possibility of his destruction.
