In April 2004, the French were held in suspense by the search for a 10-and-a-half-year-old boy who had disappeared in the middle of the night, wearing his pajamas. The days pass. The images look alike: dogs, gendarmes, battles, posters… And then life goes on, we forget a little. And one evening, six weeks later, the news broke. The little boy is found dead. Who killed Jonathan Coulom? For more than four years, the case remains unsolved.

Around noon on Saturday December 28, 1996, the postman from Blanzy, a small town in Saône-et-Loire, set off on a small tarmac path that leads to the farm at the locality of Ogle lagoon. After a few meters, he sees a body lying in the frozen ditch that borders the road. He rushes to the farm to call for help. The latter arrive quickly on site. The corpse is quickly identified. This is 20-year-old Christelle Blétry, an uneventful young woman who lives two kilometers away.
