Ep 13. The Railway Killers

In the thirteenth episode of season two of World's Most Evil Killers, titled "The Railway Killers," the focus is on a group of serial killers who terrorized the UK in the 1980s. The perpetrators, John Duffy and David Mulcahy, were responsible for the deaths of at least three women and the rape of countless others.

The episode begins with a brief overview of Duffy and Mulcahy's childhoods and early years, which provides some insight into their violent tendencies. We learn that Duffy was abused by his father and had a history of sexual deviancy, while Mulcahy had a fascination with violence and was expelled from school for attacking another student.

The bulk of the episode is dedicated to recounting the murders committed by Duffy and Mulcahy, which took place between 1982 and 1986. Their victims were typically young women who were travelling alone on trains or walking home from train stations. The killers would stalk their prey, abduct them, rape them, and then strangle them to death.

The police were initially baffled as to the identity of the perpetrators, as the crimes were spread out across different regions and there were few witnesses. However, DNA evidence eventually linked Duffy to one of the murders, leading to his arrest in 1986.

Mulcahy was arrested shortly afterwards, and both men were charged with multiple counts of murder and rape. The trial was widely publicized and the killers were dubbed "The Railway Killers" by the media.

The episode also explores the psychological profiles of Duffy and Mulcahy, as well as the motivations behind their crimes. It is suggested that both men were driven by a desire for control and domination over women, as well as a twisted sense of pleasure derived from their acts of violence.

The final portion of the episode focuses on the aftermath of the trial, including the impact it had on the families of the victims. We also learn that Duffy and Mulcahy were given life sentences for their crimes, and that they have shown little remorse or willingness to take responsibility for their actions.

Overall, "The Railway Killers" is a chilling and sobering look at the horrific crimes committed by two of the UK's most notorious serial killers. The episode does an excellent job of exploring the psychology behind their actions and the devastating impact they had on the victims and their families.
