In the first of the new series, Aleks Krotoski explores how the web has influenced detection, from uncovering Osama Bin Laden to discovering the identity of long-abandoned Jane and John Does.
As human beings, what is it in our nature that drives us to find out the end of the story - even when that story has nothing to do with us?
The online world has made the detective mystery one in which we can all play a role. Hundreds of cold cases have been re-examined and re-explored by cyber sleuths around the world - and some cases have picked up definitive leads from eagle-eyed members of the public. But what are the implications for law enforcement, and how does detection work when so many of us are playing outside of the rules?
Producer: Victoria McArthur.
It all started with the "Tent Girl"
Todd Matthews is Director of Case Management and Communications at Namus (National Missing and Unidentified Persons System). When he was a teenager, he learned of an unidentified murder victim, known only as Tent Girl. He became obsessed with finding her true identity, and in the late 1990s turned to the internet to finally find her true name. Pictured with his wife, Lori.
