A man in a mask and combat gear was fatally shot Monday morning in downtown Dallas after he opened fire with an assault weapon outside the Earle Cabell Federal Building. No one else was injured.
FBI Special Agent in Charge Matthew DeSarno identified the gunman as Brian Isaack Clyde, 22, at a news conference on a street corner near the federal building. Clyde died at the scene and was taken to Baylor University Medical Center, officials said.
Neither DeSarno nor Erin Nealy Cox, U.S. attorney for the Northern District of Texas, gave any indication why Clyde targeted the federal building. They also did not say who shot Clyde after police responded to an active-shooter call.
