Dallas • A masked gunman opened fire Monday on a federal courthouse in downtown Dallas before being fatally shot in an exchange of gunfire with federal officers, witnesses and authorities said.
Brian Isaack Clyde, 22, was pronounced dead at a hospital following the shooting outside the Earle Cabell Federal Building. Authorities offered no hint of his motive, but FBI agent Matthew DeSarno said there was nothing to indicate the presence of any other shooters or threats to the city.
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.
