Richard Leonard Kuklinski (April 11, 1935 – March 5, 2006) was an American contract killer who was convicted for five murders. Kuklinski was given the nickname "Iceman" for his method of freezing a victim to mask the time of death. The 6'5" (196 cm), 300 pound (135 kg) Kuklinski lived with his wife and children in the suburb of Dumont, New Jersey. Prior to his arrest, his family was apparently unaware of Kuklinski's double life and crimes. A New Jersey Police task force was formed after Kuklinski was suspected of two murders. An eighteen month long undercover investigation led to his arrest.
