"It is with profound sadness that I share the news of the passing of Officer William 'Billy' Evans this afternoon from injuries he sustained following an attack at the North Barricade by a lone assailant," Acting U.S. Capitol Police Chief Yogananda Pittman said in a statement. "Officer Evans had been a member of the United States Capitol Police for 18 years. 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." 

The U.S. Capitol campus went into a lockdown around 1:00 p.m. on Friday after reports of an external security threat. USCP later confirmed a suspect, now identified as 25-year-old Noah Green, had rammed into two USCP officers at the North Barricade vehicle access point on Constitution Ave.
