Masked gunman who opened fire outside Dallas courthouse identified as Army veteran

A masked gunman who traded gunfire with police outside a federal courthouse in Dallas is a 22-year-old recent college graduate who served 19 months in the U.S. Army; Casey Stegall reports.

The 22-year-old masked gunman who was shot in an exchange of gunfire with federal officers outside a federal courthouse in Dallas had been discharged from the Army, and was not the subject of any investigation, FBI Special Agent in Charge Matthew DeSarno said Monday.

Brian Isaack Clyde was pronounced dead at a hospital following the shooting outside the Earle Cabell Federal Building. Clyde opened fire about 8:40 a.m., and law enforcement immediately responded, including three officers from the Federal Protective Service who were stationed at the building.

Police closed off several blocks around the federal building.

“We are aggressively pursuing all his social media activity,” DeSarno told a press conference Monday afternoon.

His social media profiles showed photos of him with guns and ammunition.
