WASHINGTON — An armed man was wounded Monday by U.S. Capitol Police when he arrived at the Capitol Visitor Center and brandished a weapon at authorities, police said.

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.

A federal law enforcement official, who is not authorized to comment publicly, said the man was armed with a handgun.

Verderosa said the matter was "the act of a single person who has frequented the Capitol before.'' 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.

In another matter, Dawson's re-application for a license from the Tennessee Board of Funeral Directors and Embalmers was rejected in August 2014, according to board records.

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. The shooting came during a congressional recess but at a time when the city is packed with tourists, many on spring break or in the nation's capital for the annual Cherry Blossom Festival.

Following the reports, the Washington, D.C. police department tweeted that there was "no active threat to the public."

Dawson was being treated at a local hospital and was in stable but critical condition late Monday, the Associated Press reported. Police told The Washington Post that Dawson would appear in D.C. Superior Court after his release from the hospital.

The Capitol Visitor Center remained closed Monday following the incident, and the Capitol was available only for official business. Verderosa told reporters that police had located Dawson's pickup on the Capitol grounds and were processing it.

Lawmakers tweet about Capitol shooting, assure staff are safe

Diane Bilo of Cincinnati said her husband heard a single shot in the visitor center and a clip of bullets being fired. Her husband, Robert, was in the center with their two younger sons, Michael and Matt, waiting for her to return from Ohio Sen. Rob Portman's office with gallery passes.

"It was scary," Bilo said. "Police said, 'Run, run as fast as you can.'"

She was communicating with her husband and children, who were still in the center's theater, by text.

"They are sheltered," she said, adding that she was relieved to hear from them.

Matthew Melucci of Connecticut said the situation seemed under control relatively quickly, but it was frightening as it unfolded.

"We were coming out of the Capitol when we heard 'Shots fired, shots fired,'" he said, before being pulled into a security area for a half-hour.

"It was scary. I've got three children with me and my wife," he said. "It was a scary moment about what was going to happen next. We felt lucky we were there with several police officers."

Trotter and Anne Cobb of Birmingham, Ala., were eating lunch in the lower level of the center when Trotter Cobb said he heard a "crack" of a gunshot, resulting in dropped trays and glasses crashing to the floor.

"Capitol Police came out of nowhere," he said. "They were amazing."

Tune Chang, 42, and his wife, Angie, and 10-year-old daughter Amanda were headed to the center when they were stopped on the south side of the Capital and directed across the street.

Tune Chang said he didn't consider safety issues when the family decided to travel from Los Angeles to Washington for a one-week vacation.

"We're in a better situation than the rest of the world" as far as security, he said.
