Authorities believe that Charles Sobhraj - the man known as the "Hippie Killer," “The Bikini Killer,” and "The Serpent" - murdered a dozen people between 1972 and 1976. Sobhraj was known for befriending tourists in various countries, then drugging or poisoning them. He developed crime rings across Europe and Asia, always evading police. Even when he was arrested and sent to prison, Sobhraj managed to break out multiple times.
In an unexpected turn of events, a young Dutch diplomat named Herman Knippenberg laid the groundwork that eventually brought Sobhraj to justice. Here we'll explore how Knippenberg's determination to solve the murders of two Dutch tourists led to the capture of one of the most notorious serial killers of the 1970s.
