The police officer who was killed while protecting the US Capitol building has been named as William ‘Billy’ Evans.
Mr Evans, an 18-year veteran and member of the department’s first responders unit, died after being rammed by a car while stationed on a barricade in Washington DC.
The suspect behind the attack has also now been identified as Noah Green, 25, and investigators are trying to discern what may have motivated him to carry out the killing.
Mr Evans and a colleague were both crashed into while stationed at a security checkpoint 100 yards from the Capitol building on Friday afternoon.
Video showed the driver of the smashed car emerging with a knife in his hand and starting to run at the pair of officers.
One of the officers was stabbed before the suspect was shot. He later died in hospital.
A statement announcing Mr Evans’ death from the United States Capitol Police said: ‘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.
‘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 attack came amid heightened tensions in Washington after a large group of Trump supporters stormed the Capitol on January 6.
Mr Evans was hit at a checkpoint used by senators and staff on weekdays, but lawmakers are currently away on recess.
There are several more layers of security between the barricade and the Capitol building itself.
Staff who work in the massive complex were told they couldn’t enter or exit the building.
Later authorities said that there was not an ongoing threat and that the attack did not appear to be related to terrorism.

Announcing the death of one of her officers earlier, Capitol Police Acting Chief Yogananda Pittman said: ‘I just ask that the public continue to keep U.S. Capitol Police and their families in your prayers.
‘This has been an extremely difficult time for U.S. Capitol Police after the events of Jan. 6 and now the events that have occurred here today.’
Investigators are digging into the suspect’s background and examining whether he had any mental health history as they tried to discern a motive.
They were working to obtain warrants to access his online accounts.
