The bullet-ridden body of a former French intelligence officer was found in his car beside the road in the Alps. Daniel Forestier, who stood accused of plotting to assassinate an opposition politician from Congo-Brazzaville, was found covered in blood in Haute-Savoie, near Lake Léman. Officials from the police stated to the Guardian that the victim was killed “execution style,” the postmortem revealing he’d been shot five times in the heart and head.

Forestier had written multiple spy novels after serving 14 years in the General Directorate for External Security (Direction générale de la sécurité extérieure, or DGSE). Reportedly, Forestier worked in the Action Division, a clandestine unit tasked with paramilitary operations and nuclear security. The unit is also closely related to the French Special Operations Command (Commandement des Opérations Spéciales, or COS).

The murder of the former spy came six months after French authorities started an investigation into his alleged role to assassinate General Ferdinand Mbaou, a senior opposition figure and fierce critic of the president of Congo-Brazzaville, Denis Sassou-Nguesso.

Philippe Toccanier, the public prosecutor, told the Guardian that “the killing was probably a settling of scores,” adding. “There’s almost no doubt about it.”
