On April 23, according to Canadian police, Alek Minassian drove a van onto a busy Toronto sidewalk, killing 10 people, most of whom were women, and injuring 14 others. Police said Minassian allegedly posted a “cryptic message” on his Facebook account minutes before he began driving the van, an apparent reference to a post reading: “The Incel Rebellion has already begun! All hail the Supreme Gentleman Elliot Rodger!”
