Payton Gendron, 18-year-old, in heavy tactical gear, shot at shoppers and workers in a local supermarket in Buffalo, New York, killing ten people and wounding three in the attack. The shooter is being investigated for committing a racially motivated hate crime.

According to reports, he was wearing body armor and a helmet camera and opened fire at bystanders outside Tops Friendly Market at around 2:30 pm on Saturday. The market was located in a predominantly black neighborhood in Buffalo, NY.

Police identified the shooter as Payton Gendron, who was able to live stream the shooting on Twitch before the platform cut off his feed. Gendron began shooting in the parking lot located outside the supermarket.

There, the store’s security guard, Aaron Salter, tried firing multiple shots at Gendron but failed to pierce the shooter’s armor. Salter was then killed by the gunman, who then proceeded to shoot up the establishment.

When the police arrived at the scene, ten people had already been killed while three were injured. Eleven of the bystanders shot were black. Gendron tried to aim his rifle at his neck but ultimately dropped the gun and surrendered after talking with the officers.

Suspicions are being raised on what pushed Gendron to do the shooting, particularly if it was racially motivated. One instance that points to this was when the shooter said “Sorry!” and did not shoot a person hiding behind the checkout counter after Gendron saw they were white.

“This was pure evil,” Erie County Sheriff John C. Garcia said at a news conference held after the tragedy. He proceeded to call the event a “straight-up racially motivated hate crime from somebody outside of our community.”
