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

User Reviews

Excellent drama.
8 April 2019 | by Sleepin_DragonSee all my reviews

First off, it's a very sad, interesting, and real life story. The first time in our history that DNA was used by the Police to bring about a conviction, hard to imagine nowadays.

I have to give real praise to the Director and screen writer, for telling the story in a realistic, informative, factual style, that lacked the usual sensationalism associated with modern dramas.

Superbly acted, John Simm and David Threlfall in particular are excellent.

Tragic crimes, brought to life, in a fast moving drama. 8/10
