Live Updates: Ten Are Killed in Shooting at Buffalo Supermarket

A gunman who was motivated by racism opened fire at a grocery store in Buffalo on Saturday, killing 10 people and wounding three others, the authorities said.

The police said the gunman, whom they described as an 18-year-old white man from outside the city, had streamed the shooting live online. He was taken into custody after the shooting at an outlet of the regional grocery chain Tops Friendly Markets.

Officials said the gunman broadcast the attack live on Twitch, the livestreaming site owned by Amazon that is popular with gamers.

Twitch said it had taken the channel offline. The channel’s page said only that it was “currently unavailable due to a violation of Twitch’s community guidelines or terms of service.”

In a statement, a Twitch spokeswoman said the site “has a zero-tolerance policy against violence of any kind and works swiftly to respond to all incidents. The user has been indefinitely suspended from our service, and we are taking all appropriate action, including monitoring for any accounts rebroadcasting this content.”

Among the 10 victims who died in the shooting on Saturday was a retired Buffalo police officer who was working as a security guard and who engaged with the shooter after he entered Tops, officials said. He struck the suspect, but the suspect was wearing body armor. The security guard was ultimately killed. Joseph A. Amalia, the Buffalo police commissioner, called the security guard “a hero in our eyes.”

Officials said the suspect, who used an assault weapon, was heavily armed with tactical gear, including wearing a tactical helmet.

Karine Jean-Pierre, the White House press secretary, said in a statement that the president had been briefed by Homeland Security. “He will continue to receive updates throughout the evening and tomorrow as further information develops. The president and the first lady are praying for those who have been lost and for their loved ones.”

Mayor Brown said that this supermarket is essential to the community. People from the neighborhood shop at Tops: It is a store full of familiar faces. “This is painful. This does hurt,” he said.

Officials said that out of the 13 victims, 11 were Black and two were white.

Flynn said there were “certain pieces of evidence” the office has obtained in the course of the investigation that indicate racial animosity. He did not elaborate on what those pieces of evidence were.

John J. Flynn, district attorney for Erie County, said the suspect is likely to be arraigned within the hour and that the suspect will be charged with murder in the first degree.

“Whatever we need, we will not stop until justice is brought to this community,” Ross said at the presser.

Trini E. Ross, the U.S. Attorney for the western district of New York, said that the the U.S. attorney’s office will be investigating this case, along with law enforcement partners, as a hate crime and case of domestic violent extremism.

Stephen Blodgett, the special agent in charge of the F.B.I. Buffalo field office, said the shooting was being investigated both as a hate crime and a “case of racially motivated violent extremism.”

John C. Garcia, the Erie County sheriff, said that “this was a straight up racially motivated hate crime.” He added that someone from “outside of our community came to inflict evil. “I urge everyone to stay calm,” he said.

Gramaglia said that a total of 13 people were shot. Ten died at the scene, and the others suffered non-threatening injuries.

During a presser, Buffalo Police Commissioner Joseph A. Gramaglia said that the shooter, an 18-year-old white male, traveled from outside of Buffalo. The suspect shot four people in the parking lot. Three are deceased.

Byron Brown, mayor of Buffalo, said that the shooter is in custody. “The shooter was not from this community. In fact, the shooter traveled hours from outside this community to perpetrate this crime on the people of Buffalo.”

President Biden has been briefed on the shooting and the White House is monitoring the situation, a spokesman said.

Dominique Calhoun, who lives on Laurel Street, within sight of the Tops supermarket, said she was pulling into the grocery store’s parking lot when the shooting happened. She said she saw people running out and screaming, so she parked across the street. She was with her two daughters, 8 and 9 years old, and they had planned to buy ice cream. “That literally could have been me,” she said of the people who were killed. “I’m just in shock. I’ve never had something like this happen so close to home.”

Attorney General Merrick B. Garland has been briefed on the shooting, and the Bureau of Alcohol, Tobacco, Firearms and Explosives is on the scene, according to spokespeople for the Justice Department and A.T.F.

Kat Alexander, 31, was taking shelter from the rain on Saturday outside the market. “My family lives here, my nieces live here. It’s just so unfair,” Alexander, who lives nearby, said, adding that she feels like her family members have to look over their shoulders now. “This is so unfair. It’s disgusting.”

At least 10 people have been killed in the shooting at the Tops supermarket, according to a person familiar with the government’s investigation who spoke on the condition of anonymity because he was not authorized to speak before a scheduled press conference. The Associated Press also quoted law enforcement officials who said 10 people had died.

Ken Stephens, 68, a member of a local anti-violence group, said he saw several people who had been killed when he arrived at the supermarket. “I came up here and bodies was everywhere,” he said.

Marilyn Hanson, 60, said she came to the supermarket to make sure her daughter, who lives nearby, was not inside the store. “I shop at this Tops all the time,” she said. “My daughter was so scared, because that could have been me in that store.” She said she would be scared to shop there in the future.

Many were feared dead in the shooting. Witnesses said there was more than one person lying in the parking lot, and news outlets reported police officials saying there were multiple people dead.

Sonya James, special education teacher at Maritime Charter School, stood near the scene, hoping to confirm whether any Maritime students were in the store. At least a half dozen students work at the Tops supermarket, she said. “We’re so saddened,” she said.

Mark Manna, of the United Food & Commercial Workers International Union, which represents workers at the store wiped away tears as he spoke near the scene of the shooting. “It’s a dark day for these grocery store workers, and all essential workers, who just come in and punch a clock,” he said.

Daniel Love, 24, owns Love Beauty Shop, near the supermarket, and several other shops in the area. Love was inside when he heard a noise, he said. His wife is from Iraq and immediately recognized the sound of gunfire. That is when he told her to get down, he said.

Ulysess O. Wingo Sr., who represents a district adjacent to the site of the shooting, emphasized in a phone interview that Buffalo was small enough for a shooting of this magnitude to affect many residents of the city.

“With this number of people falling victim to this senseless murder — this massacre of the people in the city of Buffalo — I, unfortunately, do know some of the fallen,” he said.
