U.S. Capitol Police Chief Matthew Verderosa said the man, who is known to authorities, appeared to draw his weapon when he was shot by police. One other person, described as a 35- to 45-year-old female bystander, suffered minor injuries from flying shrapnel or debris.
The suspect was identified by a federal law enforcement official as Larry Russell Dawson of Antioch, Tenn., who had been charged last year in a Capitol disturbance.
Dawson was charged Oct. 23 with assaulting a police officer and unlawful conduct on Capitol grounds, according to D.C. court records. He was released but never appeared in court. A bench warrant was issued Nov. 19 for his arrest.
The confrontation Monday transpired in a matter of seconds near the entrance to the visitor center, which was the scene of an active shooter drill earlier in the day. The real-life incident prompted authorities to issue a shelter-in-place order, which was later lifted as police massed near the scene.
