Anthony Castellito

Anthony Castellito (disappeared June 6, 1961; body never recovered) was an American labor official who served as secretary-treasurer of Teamsters Local 560 in Union City, New Jersey. His disappearance and presumed murder were central to a 1978 criminal case against mob-connected Teamsters leader Anthony Provenzano and enforcer Harold Konigsberg.

Background In 1961, Castellito was secretary-treasurer of the 13,000-member Local 560, one of the wealthiest Teamsters locals in the United States. His growing popularity was viewed as a threat to Provenzano's control of the union.

Disappearance On June 6, 1961, Castellito was lured from his home in Lodi, New Jersey, to his summer property in Kerhonkson, Ulster County, New York, under the pretense that an associate needed to hide there. There, according to later testimony, he was ambushed by Salvatore Briguglio, Harold Konigsberg, and others. Briguglio allegedly struck him twice with a hose filled with lead, after which Castellito was strangled with a rope by Briguglio and Salvatore Sinno. Sinno entered the federal witness protection program and provided detailed testimony of the murder. Other prosecution witnesses included Ralph M. Picardo, who stated that Provenzano had confessed to ordering the killing in a Newark bar, and John A. Madratowski, a local farmer who reported hearing digging near Castellito's property on the day of the disappearance and wrote down a suspicious vehicle's license number that was later traced to Konigsberg's business.

Aftermath and significance Castellito's disappearance removed one of the few internal rivals to Provenzano within Local 560. His murder became a key case in subsequent congressional and law-enforcement investigations into organized crime's control of the Teamsters.
