Our officers then engaged that suspect. He did not respond to verbal commands,” Pittman said. After the suspect lunged at officers, they “fired upon the suspect.”The officer who died of injuries sustained at the scene has been identified as 18-year Capitol Police veteran William “Billy” Evans.“He began his USCP service on March 7, 2003, and was a member of the Capitol Division’s First Responder’s Unit. Please keep Officer Evans and his family in your thoughts and prayers,” Pittman said.The suspect who was killed by Capitol Police has been identified as Noah Green, law enforcement sources told ABC News.Authorities believe Green, 25, had ties to Virginia and Indiana, law enforcement sources said.Authorities are taking a close look at social media postings believed to be associated with Green. No clear motive has been established, sources said.Multiple agencies are investigating the incident, including the Capitol Police, D.C. Metropolitan Police Department and the FBI Washington Field Office. The FBI Indianapolis Field Office is also providing support and assisting law enforcement partners in the investigation.The other officer last was reported in “stable and non-threatening condition.”The Capitol was put on lockdown Friday afternoon. Hill staffers were sent a message from U.S. Capitol Police around 1:20 p.m. saying that “due to an external security threat … no entry or exit is permitted.” The message said people could move around inside the building “but stay away from exterior windows and doors. If you are outside, seek cover.”“We do not have the suspect on file with U.S. Capitol Police,” Acting Metro Police Department Chief Robert Contee said. “So there is no indication at this time that there is any nexus to any member of Congress.”Conte also said the incident didn’t appear to be terror related.Congress was in recess when the incident occurred, and many staff offices were closed in observance of Good Friday.There were approximately 2,300 National Guardsmen already on mission at the Capitol following the violent riot on Jan. 6, when protesters breached the Capitol — five people died, including Capitol Police officer Brian Sicknick.The D.C. National Guard deployed an “Immediate Reaction Force” to support Capitol Police during Friday’s incident, according to a spokesperson.About 40 National Guardsmen lined up with riot gear to block access to Constitution Avenue, just east of where the incident took place. Capitol Police and the National Guard also blocked off roads and pedestrian access near the Supreme Court.White House press Secretary Jen Psaki said that President Joe Biden, who is at Camp David for the holiday weekend, is aware of the incident. House Speaker Nancy Pelosi ordered flags lowered to half-staff in honor of the officer who died, a spokesperson for Pelosi said in a tweet Friday.“I just ask that the public continue to keep U.S. Capitol police and their families in your prayers,” Pittman said. “This has been an extremely difficult time for U.S. Capitol police after the events of January 6 and now the events that have occurred here today. So I ask that you keep our U.S. Capitol police family in your thoughts and prayers.”ABC News’ Mariam Khan, Alexandra Svokos, Luke Barr, Benjamin Siegel and Josh Margolin contributed to this report.Copyright © 2021, ABC Audio.
