Richard Leonard Kuklinski was an American hitman and serial killer. He was convicted of murdering six people, but confessed to and is suspected of far more murders. He was associated with members of the American Mafia, namely the DeCavalcante crime family of Newark, New Jersey, and the Five Families of New York City.
Kuklinski was given the nickname "The Iceman" for his method of freezing a victim to mask the time of death. During his criminal career, fellow mobsters called him "the one-man army" or "the devil himself" due to his fearsome reputation and imposing physique of 6 ft 5 in and 270 pounds . Kuklinski lived with his wife and children in the New Jersey suburb of Dumont. His family was apparently unaware of Kuklinski's double life and crimes.Throughout his criminal life, Kuklinski was involved in narcotics, pornography, arms dealing, money laundering, collecting debts for loan sharking, hijacking and contract killing. While his range of criminal activities expanded, he began to make mistakes. Although Kuklinski is claimed to have killed anyone who he thought might testify against him, he became sloppy regarding the disposal of his victims' bodies. Law enforcement began to suspect Kuklinski and started an investigation, gathering evidence about the various crimes he had committed. The eighteen-month long undercover investigation led to his arrest in 1986. He was sentenced to life imprisonment in 1988, with an additional 30 years added on for murdering a mob-corrupted police officer.After his murder convictions, Kuklinski took part in a number of interviews during which he claimed to have murdered anywhere from 100 to 250 men between 1948 and 1986, though his recollection of events sometimes varied. Some have expressed skepticism about the extent of Kuklinski's alleged murders, but law enforcement are confident in their belief that he was a serial killer who killed at least several dozen people both at the behest of organized crime bosses and on his own initiative.Three documentaries, two biographies, a feature film starring Michael Shannon, and a play have been produced about Kuklinski, based on his interviews and the results of the task force that brought him to justice.
