father's life in the mob, For the Sins of My Father. Philip Carlo, whose biography of Kuklinski includes the claim that he killed DeMeo, acknowledged in the postscript to a later edition that this claim was probably untrue. Peter Calabro In his 2001 HBO interview, Kuklinski confessed to killing NYPD officer Peter Calabro, who was ambushed and shot dead by an unknown gunman on March 14, 1980. Calabro was rumored to have mob connections and was investigated for selling confidential information to the Gambino family. His wife Carmella drowned under mysterious circumstances three years earlier and members of her family believed Calabro was responsible. At the time, his murder was thought by law enforcement officials to be revenge either carried out or arranged by his deceased wife's relatives. Her brothers were regarded as "key suspects," but the crime remained unsolved. The Bergen County prosecutor believed Kuklinski's confession to be a fabrication, but his successor decided to proceed with the case. In February 2003, Kuklinski was charged with Calabro's murder, and received another sentence of thirty years. This was considered a waste because it was during multiple life sentences, plus he would be ineligible for parole until he was over the age of 100. Describing the murder, Kuklinski said he parked his van on the side of a narrow road, forcing other drivers to slow to pass. He lay in a snowbank behind his van until Calabro came by at 2 AM, then stepped out and shot him in the head with a sawed-off shotgun, decapitating Calabro. He stated he was unaware that Calabro was a police officer but said he probably would have murdered him anyway. Kuklinski claimed he was paid to kill Calabro by Gambino crime family soldier (later underboss) Sammy "The Bull" Gravano, and The Bull provided the murder weapon. Gravano, serving a twenty-year sentence in Arizona for drugs, was also indicted for the murder. Kuklinski was set to testify against him. Gravano denied any involvement in Calabro's death and rejected a plea bargain, under which, he would receive no additional jail time if he confessed to the crime and informed on all his accomplices. The charges against Gravano were dropped after Kuklinski's death in 2006. Jimmy Hoffa In his 2001 HBO interview, Secrets of a Mafia Hitman, Kuklinski said he knew who killed former Teamsters union president Jimmy Hoffa. Kuklinski did not claim any personal involvement in
