On March 31, 1922, on a cold, snowy night, five members of a German farm family were murdered along with their new maid. Days before the crime, Andreas Gruber had complained to neighbors that his house key was missing and there were footprints from the woods behind the house up to the barn, but no prints leaving the area. Police would find roof tiles moved on the south and north sides of the house where someone could watch the family activities and indentions in the piles of hay in the loft where the killer stayed before butchering the family. One hundred years later the Hinterkaifeck murders of Andreas Gruber, Cazilia Gruber, their widowed daughter, Victoria Gabriel, her two children, Cilli Gabriel and Joseph Gruber and their maid servant are still unsolved.
