Shooter used AK-style rifle

A still from a CCTV camera has emerged online showing a suspect entering the Walmart wielding an AK-style rifle, which media reports have referred to as an “AK-47.” Police have not confirmed the exact make of the weapon, though it appears to be a civilian semi-automatic variant of the assault rifle.

Alleged manifesto: Anti-Hispanic, mentions Christchurch shooting

Ahead of the massacre, the suspected shooter allegedly posted a four-page manifesto online on the notorious image board, 8chan. The document, which has emerged on social media and is currently being studied by the FBI, was apparently influenced by the manifesto of the Christchurch mosque shooter, who massacred over 50 people in New Zealand in March.

The author of the alleged manifesto calls the attack on the Walmart a “response to [the] Hispanic invasion of Texas” and expresses extreme-right views, voicing his support for the Christchurch shooter.

Police Chief Greg Allen mentioned the "manifesto" during a press conference, adding that the attack might have a “nexus” to hate crime. He said, however, that the police are still looking into whether the document was indeed penned by the shooter.

Meanwhile, a relative of a witness to the shooting told KTSM-TV that the gunman was raving about “gamer revolution” – a reference to an obscure online meme – during the rampage. The “witness” account, however, turned out to be a dark prank by an unknown joker, and it remains unclear if the attacker actually made any statement during the rampage.
