The Lake Bodom murders (Finnish: Bodominjärven murhat, Swedish: Bodommorden) were a multiple homicide that took place in Finland in 1960. Lake Bodom is a lake by the city of Espoo, about 22 kilometres west of the country's capital, Helsinki. In the early hours of June 5, 1960, four teenagers were camping on the shores of Lake Bodom. Between 4AM and 6AM, an unknown person or persons murdered three of them with a knife and blunt instrument wounding the fourth. The sole survivor, Nils Wilhelm Gustafsson, led an otherwise normal life until 2004, when he became a suspect and was subsequently charged. In October 2005, a district court found Gustafsson not guilty of all charges against him.
The murders have proven to be a popular subject in the Finnish media and commonly return to the headlines whenever new information or theories surface, but the case is still unsolved.
