How DNA is Catching Killers: The Genetic Manhunt for Unsolved Crimes (Crime & Justice Documentary)

Описание: It was a landmark achievement with the implication of solving any crime. In March 2018, US police tracked down the Golden State serial killer, who had gone undetected for 40 years, by identifying members of his family on a commercial DNA database. It was the first time investigative genetic genealogy had been used to crack a case and helped spawn a new discipline.

Since then, genetic genealogy has been used to catch nearly 300 killers. If the DNA profiles of just 3% of the population are on a database, you can find anyone. A point has already been reached in the United States and China. But as DNA can easily become contaminated or transferred, DNA profiles have also led to people being wrongly convicted.

And there are wider implications at stake. When the remains of a 20-week-old foetus were found in the sewer in Georgia, the police analyzed the DNA of the foetus, and, with genetic genealogy, tracked down the mother. Faced with a public outcry following her arrest, charges were dropped. But since then, another two other women whose pregnancies also ended in unclear circumstances have been tracked down through genetic genealogy. In Hong Kong, DNA taken from cigarette butts was used to identify and publicly shame litterers.

So who should have access to these databases? And under what circumstances?

This documentary was produced by Nova Prod and directed by Gabrielle Dréan & Jérémy Frey. It was first released in 2022.
