In the mid-1980s, London lived in fear of the "Railway Killers," two men responsible for a series of brutal rapes and murders. John Duffy was caught, but his accomplice David Mulai disappeared into the shadows, a free man for over a decade. This documentary tells the true story of their sick and twisted friendship, how their partnership escalated from petty pranks to heinous crimes, and the chilling reason why one killer ultimately betrayed the other. Through detailed accounts from detectives and reporters, we learn how a chance discovery and a shocking confession brought one of the UK’s most notorious criminals to justice. The victims’ families waited over fifteen years for answers, and this is the story of how they finally got them. Absolute Crime is your go-to channel for the best crime documentaries.
