A masked gunman on Monday morning opened fire on a federal courthouse in downtown Dallas, Texas, before he was killed in an exchange with federal officers. No one else was injured as a result of the incident. Authorities identified the shooter as 22-year-old Brian Clyde. An initial search of public records did not reveal any criminal activity, but Clyde had reportedly shared images and videos of weapons on social media in recent days. An Army spokesman also confirmed that Clyde was a private first class and served as an infantryman in the Army from Aug. 2015 to Feb. 2017, when he was reportedly discharged for unspecified reasons.
