A Citroën C6 was found in the middle of a crossroads in the Bois de Vincennes, embedded in a tree. On the carpets, the doors and the bench seat there are huge pools of blood, causing a funereal smell.

No trace around the vehicle suggests that they fled or were displaced. The clue that will change the situation, however, is a little button on your pants. It allows investigators to trace the trail back to an American living on Boulevard des Capucines in Paris.
