Anthony Salvatore Casso (May 21, 1942 – December 15, 2020), nicknamed "Gaspipe", was an American mobster and underboss in the Lucchese crime family of New York City. Regarded as a "homicidal maniac", Casso confessed to involvement in between fifteen and thirty-six murders. In interviews, and in court testimony, Casso confessed involvement in the killings of Frank DeCicco, Roy DeMeo and Vladimir Reznikov. He also admitted to several attempts to murder Gambino family boss John Gotti. Following his arrest in January 1993, Casso became one of the highest-ranking members of the Italian-American Mafia to turn informant. After taking a plea bargain in March 1994, he was placed in the witness protection program. In October 1997, Casso was dropped from the program after several infractions, including bribing prison guards to smuggle contraband, giving out false statements during court trials, association with known felons and assaulting inmates. Later that year, a federal judge sentenced him to 455 years in prison for racketeering, extortion and murder. Casso died in prison custody from complications related to COVID-19 on December 15, 2020.
