Jimmy Hoffa: Disappearing Man

Using the description of the car in which Hoffa was last seen by a lorry driver, FBI investigators traced the maroon Mercury to its owner, Joe Giacalone, the son of mobster Anthony Giacalone. Giacalone claimed that on the day Hoffa disappeared, he had loaned the car to a friend, Teamster Charles "Chuckie" O'Brien, who was close to the Hoffa family and had even lived with them for a time.

The car was soon located, and O'Brien's fingerprints were found on a 7-UP bottle and a piece of paper recovered from it. Investigators believed Hoffa would have trusted O'Brien enough to get into the Mercury voluntarily, without force.

FBI agents next checked the whereabouts of the two men Hoffa was supposed to meet that day. "Tony Jack" Giacalone claimed he had been at the gym, where he went every day. Witnesses confirmed seeing him at the Southfield Athletic Club at the time of Hoffa's disappearance. "Tony Pro" Provenzano said he had been in New Jersey playing cards with friends. Both men denied knowing anything about a scheduled meeting with Hoffa.

Chuckie O'Brien, who had apparently been driving the car in which Hoffa was last seen, claimed he had delivered frozen salmon to the home of a Teamsters International vice president before helping the man's wife cut the fish into steaks on the morning of 30 July. He also said that while Hoffa waited at the restaurant, he had been at the Southfield Athletic Club with Anthony Giacalone. O'Brien further claimed he had taken the borrowed car to be washed because fish blood had leaked onto the back seat. Unlike Giacalone's alibi, however, no one at the gym or car wash could corroborate his account.

Eight days after Hoffa's disappearance, specially trained German shepherds were flown in from Philadelphia. After being given Hoffa's Bermuda shorts and moccasins to establish his scent, the dogs detected it on the back seat and in the trunk of Joe Giacalone's maroon Mercury. However, without a body, investigators lacked sufficient evidence to make an arrest.

Many theories have emerged about Hoffa's fate on that day in 1975. One suggests his body was placed in a 55-gallon steel drum, transported by truck, and buried at a toxic waste site in New Jersey. Another claims his remains were mixed into the concrete used to build the New York Giants' football stadium in New Jersey. Other theories suggest he was buried in a Michigan gravel pit owned by his brother William Hoffa, ground up at a meat-processing plant and dumped in a Florida swamp, or destroyed at a fat-rendering plant.

The number of possible killers continued to grow as investigators explored underworld connections and negotiated with convicted criminals willing to provide information in exchange for reduced sentences.

Between January 1976 and February 1977, the United States government produced internal reports based on interviews with an informant who claimed to know the full story behind Hoffa's disappearance. The informant, Ralph Picardo, was serving a murder sentence at Trenton State Prison in New Jersey. In 1975, Picardo had worked as a driver for "Tony Pro" Provenzano. He claimed that Hoffa had been lured to the restaurant meeting by Detroit mobster Anthony Giacalone for a "sit-down" with Provenzano to settle their differences.

According to Picardo, Chuckie O'Brien, who had claimed to be helping carve fish that day, picked Hoffa up from the restaurant and drove him to a nearby house. There, Teamsters business agent Thomas Andretta, Salvatore Briguglio, his brother Gabriel Briguglio, and Frank Sheeran were allegedly waiting to ambush Hoffa.

Picardo further alleged that the murder had been ordered by Pennsylvania mob boss Russell Bufalino because his cousin, William Bufalino, had a major falling out with Hoffa in 1967. Bufalino then entrusted Provenzano with carrying out the killing.

Russell Bufalino's exact whereabouts on the day Hoffa disappeared were never confirmed. However, the FBI believed there was little doubt that Hoffa had been murdered based on the information provided by Picardo.

In 1985, the FBI released a memorandum identifying Salvatore Briguglio, Gabriel Briguglio, Thomas Andretta, Chuckie O'Brien, Tony Provenzano, Anthony Giacalone, and Russell Bufalino as its principal suspects in Hoffa's murder.

Without a body or sufficient circumstantial evidence to withstand scrutiny in court, there will probably never be a conviction in Hoffa's disappearance. Although the alleged conspirators could not be charged in the case, the United States government later prosecuted many of them on numerous unrelated criminal charges.

Provenzano's Teamsters Local 560 eventually came under government oversight, severely disrupting his illegal operations. In 1978, he was convicted of the 1961 murder of Anthony Castellito. Seventeen years after Castellito's body was allegedly put through a tree shredder, Provenzano was imprisoned, where he died ten years later at the age of 81.

Anthony Giacalone was convicted of tax evasion in 1976 and served ten years in prison. In 1996, he was also charged with racketeering offences but died before the case went to trial.

Despite numerous inconsistencies in Chuckie O'Brien's alibi, he was never charged in connection with Hoffa's disappearance. He later moved to Florida, where Teamsters president Frank Fitzsimmons gave him a job, but he was expelled from the union in 1990 because of his mob connections. After surviving cancer and four heart bypass operations, O'Brien continued to live in Florida, maintaining that the government, rather than the mob, killed Hoffa.

Salvatore Briguglio was murdered in New York in 1978. At the time, he had been cooperating with prosecutors and was reportedly close to reaching an agreement to testify against Provenzano in the Anthony Castellito murder case.
