Richard Leonard Kuklinski (: April 11, 1935 – March 5, 2006), also known by his nickname the Iceman, was an American criminal and leader of a New Jersey-based burglary ring. He engaged in criminal activities for most of his adult life, which began when he distributed pirated pornography and eventually escalated to at least five murders committed between 1980 and 1984 for personal profit. His nickname derives from his freezing the body of one of his victims in an attempt to disguise the time of death.
At the time of his crimes, Kuklinski lived with his wife and children in the New Jersey suburb of Dumont. His family stated that they were unaware of his crimes. Kuklinski's modus operandi was to lure men to clandestine meetings with the promise of lucrative business deals, then kill them and steal their money. He also killed two associates to prevent them from becoming informants. Eventually, Kuklinski came to the attention of law enforcement when an investigation into his burglary gang linked him to several murders since he was the last person to have seen five missing men alive. An 18-month-long undercover operation led to his arrest in December 1986.
