The murder of Muriel Drinkwater remains one of the most infamous unsolved murders in Welsh criminal history. Muriel was a 12-year-old schoolgirl who, whilst walking home from school one day in 1946, was brutally assaulted in the woods near her home in Penllergaer, before being shot dead. Her body was discovered the following day, just a few hundred yards from where her parents had anxiously awaited her safe return from school. Over the decades, although the culprit has never been caught, several key discoveries have been made to advance the investigation. But due in part to the scientific limitations of the day, such discoveries failed to produce major breakthroughs. In this episode of Dark Land, the team applies modern day forensic techniques to the available facts. What they uncover edges Muriel’s killer closer to being identified and provides answers to at least some of the questions that her family have been asking since the day she died.
