This is Part A of F of Patrick MacKay: Two Sides of a Psychopath (Heidi Mnilk).


On Sunday the 8th of July 1973, 17-year-old German tourist Heidi Mnilk boarded the 4:57pm train to Hayes at Charing Cross station. At 5:08pm, just 90 seconds outside of London Bridge station, a scream was heard, she was stabbed and her body was thrown onto the tracks at Bermondsey. 


Her murder has never been solved. But on Thursday 17th of April at Brixton Prison, serial killer Patrick MacKay (awaiting trial for the murders of Adele Price, Isabella Griffith and Father Anthony Crean) confessed to "killing eleven people". One of them, he claimed, was Heidi Mnilk. But did he? This series explores the killings he confessed to, and which he committed. 

  • Location: Abbey Street bridge in Bermondsey, London, UK (body found)
  • Date: Sunday the 8th of July 1973 at 5:08pm (time of murder)
  • Victims: Heidi Ann-Marie Mnilk
