The Lake Bodom Murders — Finland's Most Famous Unsolved Case

On June 5, 1960, four Finnish teenagers were attacked while camping at Lake Bodom near Helsinki; three were killed and one survived with serious injuries. The attacker used a knife and a blunt object, striking while the campers slept, and was never identified in the initial investigation. The sole survivor, Nils Wilhelm Gustafsson, was charged with the murders in 2004 after new forensic evidence reexamined the case; he was acquitted by a Finnish court in 2005 after the jury found the evidence insufficient. The murders shocked Finland, inspired numerous books and a 2016 horror film, and officially remain unsolved.
