Gunman kills 10 in live-streamed racial attack on New York state supermarket

BUFFALO, N.Y. — An 18-year-old white gunman shot 10 people to death and wounded three on Saturday at a grocery store in a Black neighborhood of upstate New York, before surrendering after what authorities called an act of “racially motivated violent extremism.”

Authorities said the suspect, who was armed with an assault-style rifle and appeared to have acted alone, drove to Buffalo from his home several hours away to launch the afternoon attack that he broadcast in real time on social media platform Twitch, a live video service owned by Amazon.com.

Eleven of the 13 people struck by gunfire were Black, officials said. The two others were white. The racial breakdown of the dead was not made clear.

Court papers named the suspect as Payton Gendron of Conklin, a town of about 5,000 people in New York’s Southern Tier region near the Pennsylvania border.

He was arraigned hours after the shooting in state court on first-degree murder charges, which carry a maximum penalty of life in prison without parole, said Erie County District Attorney John Flynn. New York has no capital punishment.

Mr. Flynn said the judge also ordered Mr. Gendron to remain in custody without bail and to undergo a “forensic examination.” Mr. Gendron was scheduled to return to court on May 19.

Authorities said the teenager, reported by local media to have been a student at the State University of New York’s Broome Community College near Binghamton, had come close to taking his own life before he was arrested.

When confronted by officers at the store, the suspect held a gun to his own neck, but they talked him into dropping the weapon and surrendering, Buffalo police commissioner Joseph Gramaglia told a news briefing.

Mr. Gramaglia said the gunman shot and killed three people in the parking lot of the Tops Friendly Markets outlet before exchanging fire with a retired police officer working as a security guard for the store, but the suspect was protected by his body armor.

The guard was one of the 10 people shot to death, the nine others all being customers. Three other employees of the store, part of a regional chain, were wounded but are expected to survive, authorities said.

Shonnell Harris, a manager at Tops, told the Buffalo News she thought she heard as many as 70 gunshots and that she fell several times as she ran through the store to a rear exit.
