Two of the UK’s most renowned actors, David Threlfall and John Simm, are to join forces in new ITV drama Code of a Killer, produced by World Productions.
The drama is based on the extraordinary true story of Alec Jeffreys’discovery of DNA fingerprinting and its first use by Detective Chief Superintendent David Baker in catching a double murderer.
Filming is due to start at the end of September 2014 and will focus on how Jeffreys’ science and Baker’s investigative vision created the single biggest leap in the history of criminal investigation.
David Threlfall takes the role of David Baker who between 1983 and 1987 headed up the investigation into the brutal murders of two Leicestershire schoolgirls, Lynda Mann and Dawn Ashworth.
Only a few miles away, Dr Alec Jeffreys, played by John Simm, 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 analyse 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.
The drama will also feature Lorcan Cranitch (Penny Dreadful), Robert Glenister (Spooks), Siobhan Redmond (Between The Lines).
