A series of mass shootings killed and injured several people over the weekend in Buffalo, New York; Laguna Woods, California, and Houston Texas.
Here is what's known about each of the investigations:
18-year-old opens fire at Buffalo supermarket, killing 10
A White 18-year-old wearing body armor and livestreaming with a helmet camera opened fire at around 2:30 p.m. local time on Saturday outside Tops Friendly Market. It’s a supermarket in a predominantly Black neighborhood of Buffalo, New York.
The gunman streamed the shooting to a small audience on Twitch for several minutes before the platform cut off his feed.
According to police, the gunman began shooting in the parking lot and then moved inside the store. Security guard Aaron Salter fired multiple shots, but none penetrated the gunman’s armor. The gunman killed Salter, who was Black, and then stalked through the aisles, shooting shoppers.
When police confronted the gunman in the store’s vestibule, he put his rifle to his own neck but surrendered and dropped the gun with coaxing from the officers.

Police have identified the gunman as Payton Gendron, of Conklin, New York. Conklin is a small town about 200 miles (320 kilometers) southeast of Buffalo, not far from the Pennsylvania state line.
A document circulated widely online, purportedly written by Gendron, seemingly outlines racist, anti-immigrant and antisemitic beliefs. Among them was a desire to drive all people not of European descent from the U.S., federal authorities said. The document seemed to draw inspiration from the gunman who killed 51 people at two mosques in Christchurch, New Zealand, in 2019.
At a news briefing on Saturday, Erie County Sheriff John Garcia called the shooting a hate crime.
"This was pure evil. It was (a) straight-up racially motivated hate crime from somebody outside of our community, outside of the City of Good Neighbors ... coming into our community and trying to inflict that evil upon us," Garcia said.
The FBI is investigating the shooting as both a hate crime and racially motivated violent extremism.
California churchgoers detain gunman after deadly shooting
A man who opened fire during a lunch reception at a Southern California church on Sunday was detained by parishioners, according to a sheriff’s official who called their intervention an act of "exceptional heroism and bravery."
One person was killed and four others were critically wounded in the afternoon shooting at Geneva Presbyterian Church in the city of Laguna Woods, Orange County Sheriff’s Department officials said.
The suspect in the shooting, an Asian man in his 60s, was in custody and deputies recovered two handguns at the scene, Undersheriff Jeff Hallock said. A motive for the shooting wasn’t immediately known, but investigators don’t believe the gunman lives in the community, Hallock said.
The majority of those inside the church at the time was believed to be of Taiwanese descent, said Carrie Braun, a sheriff’s spokesperson.
Between 30 and 40 people were gathered for lunch after a morning church service when gunfire erupted shortly before 1:30 p.m. local time, officials said. When deputies arrived, parishioners had the gunman hog-tied and in custody.

2 killed, 3 hurt in Houston flea market shooting
Two people were killed and three more were taken to a hospital with injuries after a shooting Sunday at a bustling Houston flea market, authorities.
The shooting at the open-air market arose from an "altercation" that involved at least two guns and all five of the people, according to Harris County Sheriff Ed Gonzalez. He said no "innocent bystanders" were injured.
Investigators believe one of the people hospitalized was among those who opened fire and two more suspected shooters were detained at the scene, a sheriff’s deputy told a local news outlet.
