Payton Gendron, the 18-year-old accused of killing 10 people at a supermarket in Buffalo on Saturday, wrote in increasing detail of his plans to murder dozens of Black people in statements posted online over the past five months, according to a compilation of messages by a writer who identified himself as Gendron.

A review of more than 600 pages of messages by The Washington Post found that Gendron resolved in December to kill those he slurred as “replacers,” and decided in February to target Buffalo’s Tops grocery store based on its local African American population. In March, he performed a reconnaissance-style trip to monitor the store’s security and map out its aisles, the messages show. When a store guard confronted him about why he had repeatedly entered that day, Gendron made excuses and fled in what he described as “a close call,” the messages state.

Having identified the supermarket as “attack area 1,” Gendron detailed two additional Buffalo locations as areas at which to “shoot all blacks,” according to the messages, which showed that he had charted routes to each location, worked out the times needed for each shootout and assessed that more than three dozen people in all could be fatally shot.

Police confirmed on Monday that they suspected Gendron had intended to attack multiple locations. Also on Monday, FBI Director Christopher A. Wray said in a call with various law enforcement officials and community leaders: “I want to be clear, for my part, from everything we know, this was a targeted attack, a hate crime and an act of racially motivated violent extremism.”

Gendron, from Conklin, N.Y., has pleaded not guilty to first-degree murder in relation to the attack on Saturday. Three other people were also injured before Gendron was arrested at the grocery store. The shootings were streamed live online. In a separate 180-page document published two days before Saturday’s shooting, Gendron cited a racist theory that non-Whites were brought to the United States to replace White people for political purposes.

The 672-page compilation of messages reviewed by The Post was published during the weeks before the attack in Buffalo. The messages featured a screen name that Gendron used on other platforms, contained images of Gendron’s face in selfies and referenced events in his personal life, such as a speeding ticket, which The Post verified.

NBC News: New York’s red flag law should have helped thwart the Buffalo mass shooting. What went wrong?

Less than a year after a white teenager in upstate New York was investigated for making a threatening statement at school, he legally purchased a firearm, which he is accused of using to gun down 10 Black people in a racist rampage, authorities said.

The massacre at Tops Friendly Market in Buffalo on Saturday should have been thwarted by New York’s red flag law, which aims to stop people from buying or possessing firearms when they show they’re threats to themselves or others, gun policy experts said.

“It was designed exactly for this circumstance,” said David Pucino, the deputy chief counsel at Giffords Law Center, a gun-safety group.

Instead, after Payton Gendron appeared on the radar of New York State Police in June over a chilling comment about a murder-suicide he made in the classroom while he was still a minor, he was evaluated and cleared, paving the way for him to legally buy the semi-automatic rifle he is accused of using in the shooting 11 months later, law enforcement officials and New York Gov. Kathy Hochul said.

No official involved in the investigation in June initiated a court process that could have helped prevent Gendron from buying the rifle, a New York State Police spokesperson said Monday.

Now, state legislators are looking into whether those involved followed the proper protocol. “I’ve asked for the investigation of exactly what transpired there,” Hochul told Buffalo’s WKSE radio on Monday.

Hochul said a teacher had asked Gendron about his plans just before the start of summer vacation last year. He responded, “I want to murder and commit suicide,” Hochul said.

NBC News: Fox News’ Tucker Carlson under fresh scrutiny after Buffalo mass shooting.

Fox News personality Tucker Carlson is facing intense scrutiny from extremism experts, media watchdogs and progressive activists who say there is a link between the top-rated host’s “great replacement” rhetoric and the apparent mindset of the suspect in the weekend’s deadly rampage in Buffalo, New York.

The white suspect accused of killing 10 people and wounding three others Saturday at a supermarket in a predominantly Black neighborhood apparently wrote a “manifesto” espousing the white supremacist “great replacement” conspiracy theory — elements of which Carlson has pushed on his weeknight show.

The theory baselessly holds that a cabal of Jewish people and Democratic elites are plotting to “replace” white Americans with people of color through immigration policies, higher birth rates and other social transformations. The idea circulated on the far-right fringes before moving to the mainstream of conservative media.

“Tucker Carlson has made comments that directly reference this conspiracy theory on his show,” said Michael Edison Hayden, a spokesman for the Southern Poverty Law Center, an organization that tracks white supremacy, hate groups and extremism.

“The rhetoric that he espouses finds its origins in white supremacist literature,” Hayden went on to say, citing examples of websites and other publications popular with white supremacists. He added that Carlson “stops short of naming” Jewish people as the orchestrators of the “replacement,” instead using more general terms such as “the elite.”

Annie Karni at The New York Times: Racist Attack Spotlights Stefanik’s Echo of Replacement Theory.

Over the past week, Representative Elise Stefanik of New York, the third-ranking House Republican, has blasted President Biden for providing infant formula to undocumented immigrants while “American mothers” suffer amid a nationwide formula shortage.

She has attacked Democrats and “pedo grifters,” borrowing language from the baseless pro-Trump QAnon conspiracy theory that claims there is a Satan-worshipping cabal of liberal pedophiles, which has evolved into a movement on the right.

And after the deadly mass shooting in Buffalo, where a heavily armed white man is accused of killing 10 Black people at a supermarket in a racist rampage, Ms. Stefanik is under scrutiny for campaign advertisements she has circulated that play on themes of the white supremacist “great replacement” theory. That belief, espoused by the Buffalo gunman, holds that the elite class, sometimes manipulated by Jews, wants to “replace” and disempower white Americans.

Last year, in an ad on Facebook, Ms. Stefanik accused “radical Democrats” of planning what she described as a “PERMANENT ELECTION INSURRECTION.”

“Their plan to grant amnesty to 11 MILLION illegal immigrants will overthrow our current electorate and create a permanent liberal majority in Washington,” the ad said.

Stefanik originally ran as a “moderate,” but that was before she decided to suck up to Trump to advance her career.

ArizonaCentral.com: Arizona Senate to investigate Wendy Rogers over social media post on Buffalo shooting.

The Arizona Senate will investigate a social media post from state Sen. Wendy Rogers that suggested the shooter in a mass killing in Buffalo, New York, last weekend was a federal agent and part of a federal conspiracy.

The Senate voted 24-3, with three members not voting, to move forward with an investigation by the Senate Ethics Committee. The committee will now examine Rogers’ remarks “relating to the Buffalo shooting as inappropriate of an elected official with this body.”

An effort to expel Rogers, pushed by Democrats, failed on a 11-15 vote just after 4 p.m.

Rogers, a Trump-endorsed, first-term politician who belongs to the Oath Keepers and has espoused conspiracy theories, was censured by her Senate peers on March 1 after she promoted hanging political enemies during an appearance at an event hosted by Holocaust denier Nick Fuentes and threatened to destroy fellow Republicans’ careers.

Rogers also drew condemnation at the time for antisemitic statements and behavior, including a promotional photo of her next to do a dead rhino marked with a Star of David.

On Saturday, following the shooting deaths of 10 people at a Buffalo store, Rogers posted on the social media site Telegram, “Fed boy summer has started in Buffalo.”

Numerous political observers and journalists said that Rogers statement meant that she was calling the shooting was a “false flag” operation by federal authorities. The statement drew nearly 200 comments that were subsequently blocked from view by Telegram.

David Leonhardt: The Right’s Violence Problem. The Buffalo killings are part of a pattern: Most extremist violence in the U.S. comes from the political right.

Over the past decade, the Anti-Defamation League has counted about 450 U.S. murders committed by political extremists.

Of these 450 killings, right-wing extremists committed about 75 percent. Islamic extremists were responsible for about 20 percent, and left-wing extremists were responsible for 4 percent.

Nearly half of the murders were specifically tied to white supremacists:
