Cement shoes, concrete shoes, or Chicago overcoat[1] 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 a tongue-in-cheek euphemism for a threat of death by criminals. While a common trope in fiction, only one real-life case has ever been authenticated.
