A horrifying, monthslong mass rape and drugging trial concluded in France Thursday, with Dominique Pelicot and 50 other men all found guilty of the rape or sexual assault of his former wife Gisèle Pelicot.

A French court found Dominique Pelicot guilty on Thursday of repeatedly drugging and raping his wife for almost a decade, and inviting dozens of strangers to rape her unconscious body in a case that has horrified the world.

Thibaut Rey, 38, spotted the serial rapist taking images of three women at the LeClerc shopping centre and confronted him, holding his phone until police arrived to make their arrest. “Pelicot didn’t resist. He froze with terror. I saw the fear in his eyes,” he said.
