Richard Kuklinski

Richard Leonard Kuklinski was an American serial criminal and hitman. In 1988, he was sentenced to life imprisonment after being convicted of killing two members of his burglary gang and two other associates. In 2003, he received an additional 30-year sentence after confessing to the murder of a mob-connected police officer. He was given the nickname The Iceman by authorities after they discovered that he had frozen the body of one of his victims in an attempt to disguise the time of death. Among his associates, Kuklinski was known as "the one-man army" or "the Devil himself".
