Standing outside the supermarket where her father was shot dead, Deja Brown was finding it difficult to comprehend what happened.
She learned of his his death after seeing his body in a picture online.
"I seen [sic] a picture of my father online laying in the self-checkout aisle, dead," she said.
"I was broken. It just hurt me so much. Just to see my dad laying there like that.
Ms Brown's 52-year-old dad, Andrew Mackniel, was one of the 10 people killed when a gunman opened fire in a supermarket in a predominantly black neighbourhood in Buffalo, New York.
They were gunned down by a white, 18-year-old man who, authorities say, showed up at the store with the "express purpose" of killing black people. Three others were wounded.
"He was my best friend. And we came out here because my little brother's birthday was yesterday, he was turning three years old," Ms Brown told the ABC.
Authorities are calling the weekend's incident "racially motivated violent extremism".
Police said the suspect, identified as Payton Gendron, shot 11 black and two white victims.
"The evidence that we have uncovered so far makes no mistake this is an absolute racist hate crime that will be prosecuted as a hate crime," Buffalo Police Commissioner Joseph Gramaglia told reporters.
'He's a true hero'
Among the victims was Aaron Salter, a beloved community member and security guard who knew the shoppers of Tops Friendly Market by name.
When they came under attack from the gunman, he quickly sprung into action to protect his community.
The retired Buffalo police officer fired multiple times at the attacker, striking his armour-plated vest at least once.
The bullet didn't pierce, and Salter was shot and killed.
One survivor told a local news station that he and his 8-year-old daughter heard the gunshots and hid in the back of a milk fridge.
More victims named
Roberta Drury had recently returned home to live with her mother, Dezzelynn McDuffie.
Ms Drury returned home to be with her brother after his bone marrow transplant.
Ms McDuffie told The Buffalo News that her 32-year-old daughter had walked to Tops to pick up some groceries on Saturday afternoon.
Soon, Ms McDuffie saw horrifying videos circulating on social media that appeared to show the gunman shooting her daughter just outside the store.
Pearly Young, 77, ran a food pantry in the Central Park neighbourhood of Buffalo for 25 years, according to a tweet from a New York television reporter Madison Carter.
She posted that Young was a grandmother and missionary who loved "singing, dancing" and being with family.
Heyward Patterson was known as "Jitney", because he drove people to and from the Tops grocery store and helped them with their groceries, according to the Buffalo News.
He was also a church deacon.
Celestine Chaney, 65, went to Tops to buy strawberries to make shortcakes, her son, Wayne Jones, told the New York Times.
Zaire Goodman, 20, worked in the Tops store and was shot in the neck but survived.
His grandfather, Charles Everheart Sr, told Reuters that Goodman was pushing shopping carts back to the store when he was hit.
'A stain on the soul of this nation'
The gunman, who acted alone, live-streamed the attack on social media.
New York Governor Kathy Hochul said that, given the suspect had been posting his views online, social media sites should have taken action earlier.
Social media and streaming platforms such as Twitch — which said it removed the stream after less than two minutes — have grappled with controlling violent and extremist content for years.
"The user has been indefinitely suspended from our service, and we are taking all appropriate action, including monitoring for any accounts rebroadcasting this content," a Twitch spokesperson said.
US President Joe Biden condemned the attack, saying it was fuelled by hatred.
Mr Biden and his wife, Jill Biden, would visit Buffalo on Tuesday, the White House said in a statement.
The suspect has been charged with first-degree murder — an offence that carries a maximum penalty of life in prison without parole in New York — and has pleaded not guilty.
