The double murder of 13-year-old Abigail "Abby" Williams and 14-year-old Liberty "Libby" German, known more commonly as the Delphi Murders, is one the most high-profile true crime cases of the past ten years. The girls were last seen alive on the Monon High Bridge, part of the Delphi Historic Trails, in Delphi, Indiana. The case went cold for several years before Richard Allen was arrested and charged in 2022 with their murders–and then … the onslaught of social media vitriol proclaiming Allen is innocent and being framed. With my two guests, who have written a book about the case, we sort fact from fiction.
