Robert Bowers, alleged Pittsburgh synagogue gunman, left a trail of chilling, anti-Semitic social media posts

The man who authorities say opened fire at the Tree of Life synagogue in Pittsburgh, Pa., on Saturday morning, killing multiple people and injuring several others, had a long history of anti-Semitic social media posts.

The alleged gunman, Robert Bowers, 46, was taken into custody after surrendering to police. He was transported to a local hospital with unspecified injuries. NBC News reported that Bowers was armed with an “AR-15 style” rifle in addition to multiple handguns.

According to KDKA, Pittsburgh’s CBS affiliate, Bowers walked into the building and yelled “All Jews must die” before opening fire. Federal officials are investigating the shooting as a hate crime.

Bowers was also an active user of Gab, a Twitter alternative that promotes itself as supporting free speech.

An account appearing to belong to Bowers — now deactivated — was littered with anti-Semitic messages. His bio on the site read “jews are the children of satan.”

The most recent post, published less than two hours before the shooting, criticized the Hebrew Immigrant Aid Society (HIAS) for its resettlement of refugees.

“HIAS likes to bring in invaders that kill our people,” he wrote. “I can’t sit by and watch my people get slaughters.”

The post concluded with a chilling message: “Screw your optics, I’m going in.”

In another post from two days ago, Bowers wrote that President Trump is “a globalist, not a nationalist.” It also made reference to the so-called “Qanon” conspiracy.

“There is no #MAGA as long as there is a kike infestation,” he added.

In a statement, Gab administrators said they suspended Bowers’ profile once they’d been alerted to a verified account matching the name of the suspected shooter.

“We are ready and willing to work with law enforcement to see to it that justice is served,” they wrote, adding: “Gab unequivocally disavows and condemns all acts of terrorism and violence.”
