The investigation into the murders of two Leicestershire schoolgirls between 1983 and 1987 was led by DCS David Baker. He collaborated with Dr Alec Jeffreys, a scientist at Leicester University, who invented a DNA fingerprint technique in 1984. When a local teenager confessed to one of the murders, Baker asked Jeffreys to analyze DNA evidence, leading to the shocking discovery that the teenager was innocent. Baker then launched the world's first DNA manhunt, testing over 5,000 local men to find the killer.
