New series Catching Britain's Killers: The Crimes That Changed Us is set to be true crime fans next TV obsession.
The gritty BBC series, which is set to hit screens on Monday, 7th October, follows the unique story of three murder inquiries that had a huge impact on how investigations are conducted today - influencing laws, transforming police interrogation and revolutionising forensic detection.
The first episode delves into the horrific murders of 15-year-olds Lynda Mann and Dawn Ashworth, who were attacked and killed under very similar circumstances in Leicestershire in the 1980s.
The local teenagers, who hailed from Narborough and Enderby, were raped and strangled on separate occasions; 1983 and 1985, before their bodies were found in the same parkland three years apart.
The tense hour-long instalment shows how the hunt to find their killer, Colin Pitchfork, led to the crucial discovery of DNA fingerprinting and the creation of Britain's DNA database, which was a world first.
As well as exploring the database, it showcases the development and evolution of DNA fingerprinting as an investigative tool that would eventually lead to convictions for crimes that had until then been impossible to solve.
Sharing details of the other two episodes, BBC explained the series meets: "the mother whose fight for justice after the murder of her daughter led her to take on the legal establishment and challenge an 800-year-old law.
"And it reveals how a shocking miscarriage of justice in the 1970s exposed the dark secrets of police interrogation, leading to a radical overhaul of police powers and a brand new method of investigation."
Weaving together interviews with police officers, local journalists, forensic scientists as well as friends and close relatives of the victims, viewers get an in-depth look on how harrowing crimes were solved.
Catching Britain's Killers: The Crimes That Changed Us airs on BBC Two on Monday, 7th October.
