A retired couple was found dead at his home in Notre-Dame-de-Riez and the son was taken into custody, we learned on Sunday from the Sables-d'Olonne prosecutor's office, which favors the track criminal.
The bodies were discovered overnight from Saturday to Sunday and the son, born in 1984 and living with his parents, was arrested at the scene.
The couple did not die by firearm, the same source said, without being able to indicate for the moment the operating mode used or the origin of the dispute that may have led to the tragedy.
Autopsies will be performed in the coming days.
