Three of the most deranged serial killers in recent history are profiled here. Gary Evans was a psychotic antiques dealer who killed anyone who crossed him and was able to escape from custody numerous times. Joseph Duncan killed men, women and children in a rampage that lasted over eight years before he was finally caught. Robert Black was a serial killing pedophile who terrorized the Scottish countryside for five years. He was able to evade capture for years after being subject of the largest manhunt in the history of the United Kingdom.
