Unsolved Cold Cases and a Serial Killer

The podcast episode discusses a cold case investigator's attempts to solve 9,000 unsolved homicides. In particular, it focuses on Detective Richard Bankston, who was assigned to a 30-year-old triple homicide case. The victims shared the same killer who had raped and strangled them, leaving no evidence behind. The episode explores how new evidence surfaces years later when a woman named Jeannie Loudenberg reports that Adolf Leidenberg had confessed to the murders and shared details with her. Despite initial doubts from the police, Jeannie's story leads to the reopening of the case. However, without solid forensic evidence, the investigation stalls until slides from the coroner's office containing DNA evidence are discovered. With this breakthrough, undercover cop Bob Dinlocker manages to obtain Adolf's DNA sample, which matches the evidence from the oldest victim. Adolf Leidenberg is eventually arrested, charged, and convicted for the murder of Lois Petrie.
