When he used his laptop, he was told to contact the handler via Pidgin, another encrypted tool. He was told to create an account with Tutanota, a secure email service.

“OK, brother, now pay attention,” one of the messages begins, instructing the then-23-year-old to head to the suburb of Aulnay-sous-Bois, where he would find the automatic weapons in a bag left in a locked car parked near a sandwich shop. “Search among the cars that are parked there near the big road and look for a Renault Mégane,” the message said. “Look at the front right tire — you’ll find the keys placed on top.”
The handler then instructed him to store the weapons in another car in a parking garage 10 miles away, a precaution in case his apartment was searched.
