In the summer of 1991, a serial killer stalked Los Angeles, strangling women with their bras. LAPD detectives had never heard of a transatlantic serial killer, so they didn't make a connection with the bodies turning up in the woods outside of Vienna, Austria.
While the LAPD braced for the killer to strike again, detectives in Vienna ran into a series of dead ends. In the intense press coverage of the murders, one reporter - the flamboyant writer and freelance journalist Jack Unterweger - distinguished himself for his hard-hitting radio and newspaper stories on the phantom-like killer.
Despite months of investigation, the police failed to find a suspect. That was until they began to consider a tip that at first seemed too far-fetched to be true: that the "Vienna Woods Killer" was Jack Unterweger himself.
