DALLAS — A masked gunman was fatally shot on Monday after open firing on a federal building in Dallas.
The Dallas Morning News reports that according to witnesses, gunman Brian Clyde parked his car at a street corner in front of the Earle Cabell Federal Building in Dallas.
He then ran and began shooting at the building at 8:40 a.m.
According to the publication, security personnel on the first floor pushed people to the ground as Clyde fired shots outside.
The 22-year-old former army soldier was shot while exchanging gunfire with federal officers who responded to the incident. He died at the scene.
Police inspected Clyde's 2003 Nissan Altima, and found a suspicious device, which they then detonated using controlled explosions.
Authorities say they are looking into a motive for the attack, and are actively looking into Clyde's social media presence.
His Facebook page was taken down Monday afternoon, but online posts included rants about the U.S. government, and photos of ammunition, according to CBS DFW.
