Richard Leonard Kuklinski, a.k.a. "The Iceman", was a serial killer (possibly prolific), hitman, poisoner, and gangster. While Kuklinski is reputed to have killed his victims in a variety of ways, including shooting, bludgeoning, stabbing, dismemberment, using hand grenades, chainsaws, fire and even a bomb attached to a remote controlled toy car, he claimed that his favorite weapon was cyanide because it was difficult to detect during an autopsy and could easily be administered. He stated that he liked injecting it into the victims' hamburgers while they were in the bathroom and that he carried a nasal spray bottle filled with a cyanide solution and killed some victims by spraying it into their faces. He also claimed to have brutally tortured many victims before killing them and to have made some victims bleed non-fatally before tying them up and leaving them in rat-infested areas to be eaten alive. Additionally, he would freeze the bodies of some victims in an industrial-sized freezer to make it more difficult to establish the time of death, hence his nickname, "the Iceman".
