The 1970s

The 1970s are the book’s hinge between the disappearance of Jimmy Hoffa and the long, contested effort to explain it. In the summer of 1975, public investigations brought the Mafia’s covert political connections into view even as Hoffa vanished; by 1978, a supposed confession and the reported exhaustion of major leads had turned the decade into a story of disclosures that did not settle the mystery.

1975: Disappearance and covert operations

On July 30, 1975, Hoffa entered the Detroit house that became central to Frank Sheeran’s account of the killing. The book’s later presentation of the house gives the date and place a stark material importance: the disappearance was not simply an absence, but a last known arrival whose meaning would be disputed for decades.

That same summer, the United States Senate’s Church Committee held closed-door hearings on suspected Mafia involvement in the Bay of Pigs invasion and a plot with the U.S. Central Intelligence Agency to assassinate Fidel Castro, primarily with poison. The committee, chaired by Frank Church, heard evidence about the 1961 invasion and the anti-Castro plot known as Operation Mongoose. At the hearings’ outset, the CIA acknowledged the Mafia’s assistance in the invasion and the existence of the plot. The revelations placed organized crime’s political reach into an official record, but did not make every allegation or individual role equally certain.

The hearings were shadowed by deaths and testimony. Sam Giancana was assassinated a few days before he was scheduled to testify, and therefore never appeared before the committee. His lieutenant Johnny Roselli testified under oath at length in closed session; a few months later, Roselli was also assassinated, and his body was found in an oil drum. In June 1975, Time reported that Russell Bufalino and Giancana were the crime bosses behind the Mafia’s connections to the CIA, the invasion, and the Castro assassination plot. The juxtaposition of official inquiry, press reporting, and witnesses killed before or after testimony gives the decade’s disclosures a distinctly incomplete character.

The committee’s findings and the CIA’s admission also had institutional consequences: the committee drafted legislation restricting CIA involvement in the affairs of sovereign nations, and the legislation passed. The book notes that these reforms later became controversial after the September 11 attacks, when some commentators argued that the committee had gone too far. Thus the decade’s investigations did not end with exposure; they also altered the terms of debate about intelligence authority.

Hoffa’s case and the limits of the record

The disappearance remained unresolved even as the book locates the house Hoffa entered and presents Sheeran’s account of what happened there. The house became a point where oral testimony could be compared with physical traces, but not automatically confirmed by them. The distinction matters: the existence of a location associated with the account is not, by itself, proof of every claim about the killing.

The book’s later reporting describes how Fox News, following leads in an advance copy, obtained permission to test the house’s floorboards with Luminol. The test detected eight small indications of blood along a trail from the vestibule down the hallway toward the kitchen, a pattern the account says matched Sheeran’s description. In 2005, the Bloomfield Township Police Department sent sections of flooring to the FBI Laboratory. The lab identified human male blood, but its DNA did not match Hoffa’s. David Gorcyca said the result neither corroborated nor refuted Sheeran’s confession; Michael Baden argued that the finding did not speak against it. The test therefore sharpened the evidentiary question without resolving it.

1978: A disputed confession

The decade also contains an earlier, uncertain claim that Sheeran may have confessed by telephone to Steven Brill, author of The Teamsters. In 1978, the FBI believed Sheeran had confessed and pressed Brill for a tape. Dan Moldea later wrote that Brill had told him over breakfast at a hotel that he possessed a recorded confession. Brill publicly denied having one in the New York Times, perhaps, the book suggests, to avoid becoming a witness who might need protection. The account preserves the disagreement rather than treating the alleged recording as established fact.

That disputed episode anticipates the larger problem of the book: how to weigh a confession whose circumstances, transmission, and corroboration are all consequential. Sheeran’s later interviews were not simply a repetition of an uncontested 1970s statement. The author first interviewed him in 1991, when Sheeran admitted more than he later felt comfortable with and ended the session; interviews resumed after Sheeran contacted the author in 1999 and continued for four years. Sheeran read and approved each chapter and then the manuscript as a whole. These later steps shaped the account of the decade, but do not erase the difference between a recorded, contemporaneous confession and a retrospective narrative developed through questioning.

The decade’s afterlife in evidence

The book also recounts a purported letter from Hoffa, said to date from 1974, that Sheeran handed the author during the later interview process. More than half repeated information Sheeran had already given, while the rest could support a version of events he had promoted elsewhere. Examination showed that the paper was manufactured in 1994 and that the signature had been placed over a faint photocopy of an authentic Hoffa signature. The publisher cancelled the book deal. Sheeran conceded that the forgery had given him a way out if the pressure became too great. The episode does not by itself disprove his account of the 1970s, but it makes the management and reliability of his testimony part of the historical record.

The federal record that emerged later remained incomplete as well. In 2002, after pressure from the media and Hoffa’s children, the FBI released a 349-page summary of the case. Names, interview passages, and entire pages were missing or censored; the Detroit Free Press reported that the material suggested the FBI’s most significant leads had run out in 1978. The decade thus ends not with a solution but with a reported investigative dead end. In the book’s structure, the 1970s supply both the decisive events and the gaps that later interviews, documents, and forensic tests try to bridge—without making the disappearance’s evidence wholly conclusive.
