causes and Lucchese took over the family. On August 15, 1959, Corallo testified before the U.S. Senate Select Committee on Improper Activities in Labor and Management. The senators wanted Corallo to explain the theft of $70,000 from Teamsters Union local 239 by using names of dead mob members. Like many other mobsters, Corallo refused to answer any questions; he pleaded the Fifth Amendment 120 times during his two-hour interrogation. On December 7, 1961, Corallo was indicted on charges of trying to bribe New York Supreme Court Justice J. Vincent Keogh and former U.S. Attorney Elliot Kanaher. Corallo wanted them to drop a bankruptcy fraud case against one of his associates. On June 17, 1961, Corallo was convicted of bribery. On August 2, 1962, Corallo was sentenced to two years in state prison. Family boss On July 13, 1967, Lucchese died of a brain tumor. By nearly all accounts, Corallo was Lucchese's choice to succeed him. However, on December 18, 1967, Corallo was indicted on charges of receiving a kickback payment from a contractor for the renovation of the Jerome Park Reservoir in the Bronx. Also indicted was James L. Marcus, the former city water commissioner, who had started dealing with Corallo due to loanshark debts. On June 19, 1968, Corallo was convicted in the Marcus bribery case. On July 26, 1968, Corallo was sentenced to three years in federal prison. With Corallo in prison, the Commission designated Carmine Tramunti as interim Lucchese boss. Some historians have speculated that Corallo became boss immediately upon his 1970 release from prison, and that Tramunti was only an "acting" or "front" boss for the next three years. On May 7, 1973, Tramunti was sentenced to 15 years in federal prison. Corallo then became the indisputable boss of the Lucchese family. One of Corallo's first moves as boss was to take over gravel distribution in various areas of New York such as Long Island. In owning major gravel companies in his territories or areas of influence, Corallo increased the Lucchese crime family's influence in the construction industry and with the unions involved. The garbage industry would be next on his list. With the help of a union official named Bernie Adelstein, the front business would be called Private Sanitation Industry Association. Next, with the help of Lucchese capo Paul Vario and his crew, Corallo would gain power at John F. Kennedy International Airport. Mafia Commission
