Code of a Killer (2015)

In the heart of Leicestershire between 1983 and 1987, a sinister shadow loomed as two schoolgirls met with brutal ends. The task of dissecting this chilling mystery fell upon DCS David Baker, a man determined to bring justice. Meanwhile, only a stone's throw away, Dr Alec Jeffreys, a pioneering scientist at Leicester University, was on the brink of a groundbreaking discovery. On September 10, 1984, he unlocked the secret to reading every individual's unique DNA fingerprint, a tool that would soon intertwine his path with Baker's. When a local teenager confessed to one of the murders, yet denied the other, a baffled Baker sought the expertise of Dr. Jeffreys. Together, they delved into the DNA evidence, only to make a startling revelation - the teenager was innocent, his confession a bewildering falsehood. Confronted with this twist in the tale, Baker embraced the unknown, courageously initiating the world's first ever DNA manhunt. This unprecedented quest led him to test the DNA of over five thousand local men, as he tirelessly hunted down the elusive killer. Code of a Killer is a gripping tale of innovative science and relentless pursuit, as two men race against time to bring a ruthless murderer to justice.
