The FBI identified the suspect as Brian Isaack Clyde, 22. No one else was reported injured. A Dallas Morning News photograph of Clyde shows him holding a semi-automatic rifle and wearing an army uniform and a belt full of ammunition. Wearing a ski mask and what appeared to be a bulletproof vest, Clyde reportedly opened fire on bystanders near the courthouse parking lot. He then reportedly fired at the building, shattering the glass front doors.

The shooting took place on the same day that Dallas’s new mayor, Eric Johnson, was sworn into office along with several new city council members. Clyde served in the Army from 2015 to 2017.
