When the 2022 drought dropped Lake Mead to its lowest level since filling in 1937, boaters at Hemenway Harbor found a corroded 55-gallon barrel containing human remains. The victim had been shot in the head, execution-style, and the Kmart clothing inside dated the crime to the late 1970s or early 1980s - a period when the Chicago mob ran Las Vegas. Three years on, the barrel victim is still unidentified.
