Murder of Éric Masson: how investigators found Ilias Akoudad in a cellar, after several days of tracking. The 22-year-old accused continues to deny the facts.

Jérémie Bosse-Platière, the director of the Avignon PJ at the time and five other police officers tell how the investigation led them to a cellar. The working conditions are trying: around them, the profession is in mourning and the affair takes on a national dimension. The two brigadiers wear civilian clothes, t-shirts, tracksuits and sneakers, when they rush in.
