William “Billy” Evans was an 18-year veteran of the department who began his service on March 7, 2003, Acting U.S. Capitol Police Chief Yogananda Pittman said in a statement.
“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,” Pittman said. “Officer Evans had been a member of the United States Capitol Police for 18 years.”
She said Evans was a member of the division’s First Responder’s Unit.
Evans and another Capitol Police officer were injured after a driver rammed into a barrier on the Senate side of the Capitol complex.
The suspect, identified as Noah Green, 25, exited the vehicle and attacked police with a knife, officials said. He later died of his injuries.
The attack prompted a brief lockdown of the Capitol, which has seen a number of violent incidents in recent years, including the Jan. 6 riot in which five people died, including a Capitol Police officer. Two officers died of suicide after the attack.
