Dubbed The Railway Killers, the sexual predators were responsible for a spree of horrific attacks in the 1980s.

Who is Railway Killer John Francis Duffy?
John Duffy, born 1959, was a brutal rapist and killer who attacked lone women at railway stations throughout southeast England and London.
He was at first thought to have carried out his heinous crimes alone and was sentenced to life imprisonment for the murders.
Duffy and David Mulcahy had been life-long friends since their school days in North London.
Both men are said to have been victims of bullying while schoolboys.

Duffy later married and became a martial arts fanatic.
He was already known to the cops due to an assault on his wife and he was found carrying a knife.
It is thought the pair attacked at least 19 women, killing three of them.
On July 1, 1982, Duffy and Mulcahy attacked and raped a woman close to Hampstead Station in London’s Hampstead village.
For the next 12 months women were assaulted across London and its suburbs.
In a bid to catch the culprit – initially, they weren’t sure if the crimes were carried out by just one person – police set up Operation Hart, the largest investigation to take place in the UK since the Yorkshire Ripper inquiry.
In the fall of 1983, the attacks suddenly stopped, with police later finding out this coincided with Duffy’s separation from his wife.
The attacks started up again in early 1984.
In July 1985, three women were brutally raped on the same night, all in the Hendon and Hampstead area.
Duffy and Mulcahy were brought in for questioning but were eventually released.
However, in August 1985, after a bout of domestic violence at his home, where he attacked his wife, Duffy was arrested.
In September 1985, a woman was attacked in Barnet with the victim giving cops a description of her attacker that fitted Duffy’s profile.
He was brought in for questioning once again but was eventually let go after the victim failed to recognise him in an identity parade.
On December 29, 1985, Alison Day, 19, was dragged off a train by Duffy and Mulcahy at knifepoint and raped repeatedly.

She was then strangled with a piece of string.
It was the first time the pair had killed their victim, fearing that she would easily identify the pair.
Maartje Tambozer, 15, was abducted from Horsley station in East Surrey on April 17, 1986.
After being raped and strangled, the teenager’s body was set on fire.
On May 18, the victim was local TV presenter Anne Locke, 29, who was abducted as she got off a train in Hertfordshire and later murdered.
In October 1986, a 14-year-old schoolgirl managed to survive after she was raped by both men.
While stalking a woman in a park on November 7, Duffy was discovered and arrested.
The next day, he was charged with three murders and seven counts of rape.
Mulcahy was also arrested but later released due to lack of evidence.
Duffy was put on trial in February 1988 and was convicted of two murders and four rapes, though he was acquitted of raping and killing Anne Locke.
He was given a minimum sentence of 30 years by the judge.
Who is Railway Killer David Mulcahy?
Cops also suspected Mulcahy had been involved for several years but didn’t have the evidence to charge him.
It was only after Duffy implicated him 15 years after he had been convicted could they act.
Mulcahy, a married father of four, had been tracked for several months by police before his arrest.
As they fed their newfound predilections they treated their victims as objects rather than persons.
Prosecutor
DNA tests which were not used in the original trial but were now available managed to provide the evidence to convict Mulcahy.
He stood trial in 2000 with Duffy appearing as a witness, giving graphic evidence over 14 days.
A former employee at a cab firm he worked at said he despised women.
Lola Barry, a controller at the company, said: “He liked women to be at the kitchen sink where they should be, or in bed.”
She said Mulcahy had once crept up behind her in the office.
Barry said: “He actually got me round the neck, saying ‘How does that feel, are you scared?'”
Prosecutor Mark Dennis said at Mulcahy’s trial: “As they fed their newfound predilections they treated their victims as objects rather than persons.”

It was “only a comparatively small step” between the violence of the rapes and the murders – and Mulcahy was the first to take that step.
“He was the instigator and prime mover in the murders, and the one for whom the sexual abuse had become insufficient to satisfy.”
Mulcahy claimed he was innocent, but on February 5, 2001, he was given three life sentences for murdering three women.
He received 24-year jail terms on each of seven counts of rape and 18 years each for five conspiracies to rape, to run concurrently.
Where are the Railway Killers now?
Both Duffy and Mulcahy remained locked up for their crimes.
Duffy is behind bars at HMP Frankland, County Durham, while Mulcahy is an inmate at HMP Full Sutton near Pocklington in East Yorkshire.
With the sentences handed to the pair, it is unlikely they will be released any time soon, as they pose a serious danger to the public.
The documentary, The Railway Killers, combines dramatisation of the murders with interviews with key figures involved with the case.
The three-part series delves into the devastating impact of the crimes committed by Duffy and Mulcahy, culminating in the shocking revelation of their identities as the killers.
The first episode focuses on the disappearance of Alison Day, who went missing in December 1985 after stepping off a train.
In the second episode, the police intensify their hunt for the culprits responsible for the murders of Day and teenager Maartje Tamboezer.
The final episode explores the events nine years after Duffy’s eventual capture and sentencing to life imprisonment for murder and rape.
The Railway Killers is available to stream on My5.
