Given the threats to nationwide organizations, the FBI is opening a domestic terrorist investigation into the shooting, FBI special agent in charge of the San Francisco office John Bennett said.
The FBI has not made a conclusion as to his motivation, and the shooter left no manifesto, Bennett said. The gunman was exploring violent, competing ideologies, and “there was nothing that was all one sided or the other,” he said.
In a search of his digital media, the FBI found a list of nationwide organizations that may have been potential targets. Those include religious, government and political organizations, including federal buildings, courthouses, and the Garlic festival.
The gunman was wearing body armor when he fired 39 total rounds into the crowd, Chief Smithee said. He had a 75-round drum magazine that fit into his weapon, and there were 71 rounds left in the drum when he died. In addition, he had two 40-round magazines on his body, two 40-round magazines on the ground, and one 40-round magazine that was on or near him, Smithee said.
A Remington shotgun was found in his vehicle, and his nearby backpack had two loose rounds, a rifle scope, flashlight, shovel and buckshot rounds for the shotgun.
Law enforcement sources previously told CNN of finding extremist material in the shooter’s Nevada apartment.
