The Hintakleifach Murders

Hintakleifach remains one of Germany's most talked about unsolved crimes. Over the years, police have considered a total of 105 potential suspects. Despite several arrests, no one has ever been charged. In 2018, former detective Conrad Mueller finally parted with evidence he had collected on the case and gave it to the Bavarian police museum in Ingolstadt. His documents now sit alongside a range of other displays at the museum's Hinterkifek exhibit which will close next year.
