'The Iceman Confesses: Secrets of a Mafia Hitman' (2001)

Interviews with contract killer Richard Kuklsinki present a profile of a sociopath who claimed to have killed hundreds over three decades. Bereft of conscience, the mafia henchman earned the nickname “Iceman” by freezing the bodies of his victims to obfuscate detecting time of death. Kuklinski lead a double life as a committed provider to three children and a wife, all of whom he managed to deceive. That existence came crashing down thanks to a hair-raising ATF sting.
