18-year-old Mathilde left home with her boyfriend, two cousins and three friends to go to Tek\u2019Noz, a three-day festival on farmland in Brittany. The group looked out for each other and checked in constantly. But by Sunday morning Mathilde was nowhere to be found. At the same time, Gendarmes were hoping to identify the body of a young woman found at the edge of the woods. Once they made the link, the search for the killer was on. More than 40,000 people attended the teknival and finding the perpetrator would be no small feat.\n\xa0\nFor pictures and more information, join us on Facebook\n\nWant to support our podcast?
