• Bowers is believed to live in the Versailles borough of Pittsburgh, and has been described as a heavy set, white male with a beard.

A gunman armed with an AR-15 and handguns stormed the Tree of Life Synagogue in Pittsburgh on Saturday, killing at least eight and injuring at 12 more.

The gunman, who police believe is 48-year-old Robert Bowers, was arrested at the scene after firing upon officers when they first arrived, wounding at least three.

The local CBS affiliate KDKA reported that the gunman was also wounded and was crawling on the ground from his injuries.

Bowers is believed to live in the Versailles borough of Pittsburgh, and has been described as a heavy set, white male with a beard, KDKA reported.

He reportedly entered the synagogue shouting "All Jews must die," and had written anti-Semitic posts on social media. Pittsburgh authorities tweeted that the "shooting will be prosecuted as a Hate Crime and the FBI will be leading the investigation."

An hour before the shooting, Bowers wrote on a social media platorm called Gab under the name One Dingo that "HIAS likes to bring invaders in that kill our people. I can't sit by and watch my people get slaughtered. Screw your optics. I'm going in," according to Heavy.com.

HIAS stands for Hebrew Immigrant Aid Society, which helps provides humanitarian aid and assistance to refugees.

Gab promotes itself as a free speech platform, which many white supremacists have turned to after being kicked off Twitter and other websites.

Gab removed Bowers' profile shortly after the shooting.

Bowers wrote on his Gab profile that "jews are the children of satan." He also made several anti-immigrant comments, Heavy.com reported.

Bowers was apparently opposed to the Trump administration, saying he did not vote for Trump and reportedly calling him a "globalist, not a nationalist."
