Nine months after disappearance of Émile, bones belonging to him were discovered. A hiker discovered a ‘skull’ and ‘teeth’ which correspond to the body of the two and a half year old boy.

The DNA has spoken but the mystery is not resolved. When did Émile die? How? What? A painstaking job begins, according to the Verdun forensic doctor, Bruno Frémont, known worldwide for having identified the first poilu using his DNA.
