A white supremacist just killed 21 people and wounded at least 20 more at an El Paso Walmart:

A mass shooting at a Walmart in the Texas border city of El Paso that has left 20 people dead and 26 injured is being investigated as a possible hate crime, Texas officials said.

A 21-year-old white man is in custody after the mass shooting, one of the deadliest incidents in Texas history, El Paso’s police chief said. Local news outlets reported the name of the suspected shooter, but his name has not yet been officially released by law enforcement. A local TV station published what it said was a picture of the suspect from CCTV footage.

There was “little to minimum force” used when law enforcement took the suspect into custody, El Paso police spokesman Robert Gomez said at an earlier press conference. “No law enforcement personnel fired their weapon.”

“It happened without incident so I can assume that the person dropped his weapons,” Gomez added.

Law enforcement officials are investigating “a manifesto from this individual” that suggests the incident may be a hate crime, police chief Greg Allen said. He added that law enforcement still needed to “validate for certain” that the document under investigation was from the arrested suspect.

Investigators are “reasonably confident” that the Walmart shooting suspect posted the document on 8chan, an extremist online message board that often features racist content, senior law enforcement officials told NBC News.

If the manifesto is authentic, it would make it the third mass shooting announced in advance on 8chan in less than five months.

The 8chan document under investigation by Texas law enforcement described a gun attack that was intended to be “a response to the Hispanic invasion of Texas”.

God bless America, huh?
