Pennsylvania's 47 Years Cold Case Solved by a Coffee Cup | True Crime Documentary

47 years ago, a young woman was murdered right inside her own apartment in Lancaster County, Pennsylvania, leaving behind her newlywed husband and a community living in fear. Authorities interviewed 300 people, formed a task force, consulted criminologists, but found no suspect and no leads to pursue. The investigation eventually reached a dead end. However, through all those years, the only DNA sample from the crime scene was never discarded. It was carefully stored through generations of investigators. Then, a genetic genealogist decided to try a strategy that had never been used before—tracing the family tree back four centuries to a small village in southern Italy—and what she found pointed directly to a man who had been living right in Lancaster County for nearly half a century in a way no one could have imagined.
