Richard "The Iceman" Kuklinski committed his first murder at the age of 14. In his early days he killed anyone that annoyed or slighted him. He went on to become a mafia hitman and eventually formed his own crime ring. He earned the Iceman moniker for his method of freezing his victims, sometimes for years, in order to confuse law enforcement as to the victim's time of death. Law enforcement believes that the body count of The Iceman could be as high as 200.
