Episode 5 - Unsolved Murder Case: Hinterkaifeck

In this episode of The one by one True Crime, Lisa and Jean-Paul revisit one of Germany’s most notorious unsolved murder cases: Hinterkaifeck. At the end of March 1922, six people were killed on an isolated farmstead near Gröbern in Upper Bavaria: Andreas and Cäzilia Gruber, Viktoria Gabriel, her children Cäzilia and Josef, and the newly arrived maid Maria Baumgartner. The episode follows the discovery of the bodies on April 4, the reported warning signs before the crime, including tracks in the snow and noises in the house, and the unsettling possibility that the perpetrator may have remained on the farm afterward. It also examines the limits of the 1922 investigation, the role of suspects such as Lorenz Schlittenbauer, disputed motives, lost evidence, and later attempts to review the case. A sober look at facts, rumors, and the enduring mystery of Hinterkaifeck.
