Cement shoes, concrete shoes, or Chicago overcoat is a method of murder or body disposal, usually associated with criminals such as the Mafia or gangs. It involves weighing down the victim, who may be dead or alive, with concrete and throwing them into water in the hope the body will never be found. In the US, the term has become tongue-in-cheek for a threat of death by criminals. While a common trope in fiction, only one real-life case has ever been authenticated. Cement shoes involve first binding, incapacitating or killing the victim and then placing each foot into a bucket or box, which is then filled with wet concrete (a mixture of cement powder, rock, water and sand), or even simply cement powder and water. Typically in films and novels, the victim is still alive as they watch the concrete harden, heightening the torture and drama. After the concrete sets, the victim is thrown into a body of water such as a river, lake or the ocean. Real-life incidents Despite being a theme in Hollywood movies like Lady in Cement and books like E. L. Doctorow's Billy Bathgate, whether such a cumbersome and time-consuming method of execution was practical remained in question. Cement takes many hours or even days to fully harden and, until 2016, there was never a documented case—although crime historian Thomas Reppetto said there have probably been real-life examples that have never been found. In May 2016, the first and only documented case of "cement shoes" was reported. The body of Brooklyn gang member Peter Martinez, aged 28, better known on the streets as Petey Crack, washed up near Manhattan Beach in Brooklyn. His head was wrapped in duct tape, the immediate cause of his death. His feet and shins were encased in concrete set inside a five-gallon bucket. His body floated to the shore due to air in the concrete because it was not given enough time to dry before being thrown into the ocean. Concrete has been used as a weight to dispose of a body. In 1941, the body of Philadelphia racketeer Johnnie Goodman was found by crab fisherman in a New Jersey creek, weighed down with an block of concrete. On August 24, 1964, the body of Ernest Rupolo, aged 52, a trigger man who informed on Vito Genovese in 1944, was found in Jamaica Bay, New York, with concrete blocks tied to
