The suspected gunman was taken into custody. Law enforcement officials identified him as Robert Bowers, 46, who had apparently posted virulently anti-Semitic comments on social media. Because the shootings are being treated as a federal hate crime, the FBI quickly took charge of the investigation with local officials, authorities said,
Police sources told a local TV reporter that the gunman walked in to the building and yelled, “All Jews must die.”
Police said Bowers was armed with an AK-47 rifle and two pistols, and that he fired at the first officers who arrived on the scene.
