Stabbed & Thrown From the Train – 1973 Unsolved Case

In this episode of Crimes That Haunt Us, we dive into one of the most chilling unsolved murders of the 1970s: the brutal killing of 17-year-old German au pair Heidi Mnilk in London, 1973. On July 8, 1973, Heidi boarded a train at Charing Cross Station after a day of sightseeing. Minutes later, as the train sped past London Bridge, screams echoed through the carriages. Witnesses saw a man flee her compartment as her body was hurled onto the tracks near Bermondsey. A post-mortem revealed she had been stabbed multiple times with a 5-7 inch knife before being thrown to her death.Was this a random act of violence, or something more sinister? Just months earlier, a similar attack on the same route targeted a German woman, with the assailant professing hatred for Germans. Serial killer Patrick Mackay later confessed to the crime during his spree of 11 alleged murders—but he retracted it, and inconsistencies left the case open. Despite eyewitness descriptions and a massive police hunt, Heidi's killer has never been caught, leaving this cold case to haunt investigators and true crime enthusiasts alike.Join us as we explore the timeline, evidence, suspects, and theories behind this tragic unsolved mystery. Why does it remain unsolved after over 50 years? Could anti-German sentiment or a serial killer be the key? For the documentary version see here https://youtu.be/AGm3XysVtB0(00:00) The Haunting Case of Heidi Mnilk(0:59) Who Was Heidi Mnilk?(03:51) Heidi Boards Murder Train(4:55) Heidi is Attacked(7:26) Heidi’s Body is Found(8:30) Investigation is Launched(10:28) Murder Weapon Located(13:19) The Earlier Shocking Encounter(17:05) The Coroners Inquest(19:55) More Train Stabbings(24:56) Deborah Linsley Murder
