Two of the most diabolical serial killers in modern history are profiled. The chubby Levi Bellfield was a woman hating serial killer who was caught and convicted in 2008. He was known as the 'Bus Stop Killer' for his preference of stalking women while they were waiting for the bus. John Christie was christened 'Strangler John' during his reign of terror from the 1940s-50s. He would strangle numerous women to death, finally culminating with the killing of his own wife.
