What we know so far
In November 1983, 15-year-old Lynda Mann was found murdered beside a footpath known locally as the Black Pad, near the village of Narborough in Leicestershire. Despite a huge inquiry, her killer was never found.
In July 1986, another 15-year-old girl, Dawn Ashworth, was found murdered near a footpath called Ten Pound Lane in the next village, Enderby. This time police made a quick arrest: a young local man confessed.
But a few miles away, at the University of Leicester, a scientist named Alec Jeffreys had just discovered something that was about to change police work for ever.
