Moors Murderers Myra Hindley and Ian Brady abused and slaughtered five innocent children in Lancashire.
Four of their victims were discovered in graves on Saddleworth Moor but the remains of one other have never been found.
Pauline Reade, 16, the pair’s first victim, was on her way to a dance in Gorton in July 1963 when Hindley persuaded her to get in her car.
She drove the unsuspecting girl to Saddleworth with Brady following on his motorbike.
According to Brady, Hindley joined in with the sexual abuse and torture that followed. Brady raped Pauline.
She was beaten and stabbed and he then cut her throat from behind, making it look to Hindley as though she had been decapitated.
Brady’s thirst for murder quickly resurfaced and he told Myra he wanted to go for someone younger as Pauline had put up too much resistance.
Their next target was 12-year-old John Kilbride.
The youngster was abducted from Ashton-under-Lyne on a November Saturday afternoon.
Brady raped and killed him before returning to their car with one of John’s shoes.
When John’s grave was finally discovered, helped by “trophy” photos of Brady and Hindley smiling at the scene, his family was able to identify the missing boy partly because of his remaining shoe.
Brady was now revelling in his depravity. Keith Bennett was his next victim in June 1964.
He was abducted as he made his way to his grandmothers’s house in Manchester.
The 12-year-old was driven to the Moors by Hindley and taken to a gully next to a stream.
He was throttled and buried.
There was a huge police search but Brady had meticulously covered his tracks.
Keith’s body has never been found.
On Boxing Day that year the killers struck for the fourth time.
Lesley Anne Downey, ten, was bound, stripped and made to pose for sick sex photos. Again, no clues were left.
But arrogant Brady soon made an error that would lead to his downfall.
He befriended David Smith, 17 – the husband of Hindley’s sister – a drunken and violent ex-crook who he thought he could brainwash.
In October 1965, after luring engineer Edward Evans, 17, to their home, Brady sent Hindley to collect his new friend. David watched in horror as Brady bludgeoned the teenager with an axe. Edward was then strangled with an electric flex.
Fearing for his life, David stayed with the killers for dinner while Brady bragged all about his murder spree.
He then calmly left before running to a phone box and calling the police.
Described by a judge as “wicked beyond belief”, Brady and Hindley were convicted of the murders of Lesley Ann, John and Edward in May 1966.
They later confessed to the murders of Pauline Reade and Keith Bennett.
In 1987, after a 100-day search, Pauline’s body was finally found in a shallow grave on Saddleworth Moor.Hindley died, aged 60, in prison in 2002.
Brady, 75, is serving life at high-security Ashworth Hospital, Merseyside.
