On December 6, 1989, Marc Lépine entered a mechanical engineering class at the École Polytechnique and ordered the women and men to opposite sides of the classroom. He separated nine women, instructing the men to leave. He stated that he was "fighting feminism" and opened fire. He shot at all nine women in the room, killing six. The shooter then moved through corridors, the cafeteria, and another classroom, targeting women for just under 20 minutes. He killed a further eight before turning the gun on himself.
