Code of a Killer
DCS David Baker headed up the investigation into the brutal murders of two Leicestershire schoolgirls between 1983 and 1987. Only a few miles away, Dr Alec Jeffreys, was a scientist at Leicester University who, on 10 September 1984, invented a remarkable technique to read each individual's unique DNA fingerprint. When a local teenager admitted to one of the murders but not the other, Baker asked Jeffreys to analyze the DNA evidence left at the crime scenes. Both men were shocked to discover that the teenager was innocent, his confession false. DCS Baker then took the extraordinarily brave step to launch the world's first ever DNA manhunt, testing over five thousand local men to track down the killer.

In 1983 Dr Alec Jeffreys, a lecturer at Leicester University, enthuses to his students and less than impressed wife Sue, on the wonders of DNA. At the same time Chief Superintendent David Baker investigates the murder of school-girl Lynda Mann, setting up his base in the area where she was killed, but failing to make any progress, so that DCC Chapman orders him to concentrate on other crimes. Two years later a newspaper article highlights Jeffreys' discovery that every individual has their own unique DNA and he is called upon to help in a deportation case , which, due to his efforts, is successful. But in 1986, with Lynda Mann's murder a cold case, another young girl, Dawn Ashworth, is killed in the same way and in the same locality. Teen-ager Gavin Hopkirk is the prime suspect and admits to killing Dawn but not Lynda. Hearing of Jeffreys' success Baker seeks him out to prove that Hopkirk killed both girls but Jeffreys' findings reveal that Hopkins did not murder either of them.
