LYNDA Mann and Dawn Ashworth were murdered by Colin Pitchfork during the 1980s.
The 15-year-olds were brutally raped and slaughtered in Leicestershire by Pitchfork who became the first person in the world to be snared by DNA.
What happened to Dawn Ashworth and Lynda Mann?
The two girls were pounced upon by Colin Pitchfork, a baker and convicted sex offender who was in his 20s when he murdered them.
Given the similarities of the attack and location, police linked them.
Yet there were not enough leads or enough evidence to connect anybody to the murder and the case was not immediately solved.
When were the schoolgirls murdered?
On November 23, 1983, 15-year-old Lynda Mann took a shortcut on her way home from babysitting.
But she did not return home and her parents and neighbours spent the night searching for her.
The next morning, she was found dead.
She had been raped and strangled on a deserted footpath known locally as the Black Pad.
Then, three years later, on July 31 1986, a second 15-year-old girl, Dawn Ashworth, vanished after leaving her home to visit a friend’s house.
Two days later, her dead body was found in a wooded area near a footpath called Ten Pound Lane.
She had been savagely beaten, brutally raped and strangled.
The semen samples also revealed the same blood type.

How was Colin Pitchfork caught?
Colin Pitchfork was arrested and jailed in 1988 for the murders.
It was a revolutionary case because he was the first criminal to be trapped by DNA profiling.
He was one of thousands of local men who gave blood samples which were compared with material found on the girls’ bodies.
The profiling technology had first been pioneered by Sir Alec Jeffreys at the University of Leicester and since Pitchfork’s conviction, changed how police investigations in the future were carried out.
He was jailed for a minimum of 30 years.
A new BBC documentary will focus one on the murders and how he was caught and brought to justice.
