On May 14, 2022, a mass shooting occurred in Buffalo, New York, United States, at a Tops Friendly Markets supermarket in the East Side neighborhood. Ten people, all of whom were African Americans, were murdered and three were injured. The shooter, identified as 18-year-old Payton S. Gendron, livestreamed part of the attack on Twitch, but the livestream was shut down by the service in under two minutes. Gendron was taken into custody and charged with first-degree murder. He formally entered a plea of "not guilty" on May 19, 2022. On November 28, 2022, Gendron pleaded guilty to all state charges in the shooting, including murder, domestic terrorism, and hate crimes. On February 15, 2023, Gendron was sentenced to 11 consecutive life sentences without the possibility of parole; as of that date, federal charges are still ongoing, and the federal prosecution also expressed their intention to seek the death penalty.
