The year before, 25-year-old Alek Minassian, who killed 11 people in Toronto in 2018, namechecked 4chan in a pre-attack Facebook post.
But the Guardian now adds another a story from nine days ago — when a 23-year-old shooter with 1,000 rounds of ammunition opened fire from his apartment in Washington D.C. “Just two minutes after the shooting began, someone under the username “Raymond Spencer” logged onto the normally-anonymous 4chan and started a new thread titled ‘shool [sic] shooting’.
