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. Written by dvd

Code Of A Killer
14 November 2019 | by a_baronSee all my reviews

In the 1980s, Colin Pitchfork raped and murdered two teenage girls. The story of those horrific crimes has been minutely documented because this was the first time DNA fingerprinting/profiling was used in a criminal case. Although "Code Of A Killer" is presented as a dramatisation it contains little in the way of drama, nothing graphic, and is more of a documentary, following a number of similar historically accurate dramatisations on both sides of the Atlantic. It is also in effect two stories - that of the pioneering work of Alec Jeffreys, and of the hunt for a nascent serial killer.

The mentally challenged Richard Buckland who confessed to the second murder is renamed Gavin Hopkirk, which will certainly not please the real owners of that name, bar the fictional murderer from a 2014 ITV series. The name of the man who was duped into impersonating Pitchfork to donate blood has also been changed, even though it is widely known. He paid a heavy price for that act of misguided loyalty.

Beyond the scope of this dramatisation is the unthinkable release of this monster. In 2016 he was moved to an open prison and two years later was photographed in Bristol. He has since been denied parole, and the families of his victims have mounted a national campaign to put him back in a proper prison where he belongs.
