Suspect in Capitol attack 'intentionally struck' officers, police

The U.S. Capitol Police officer killed last week when a knife-wielding motorist struck him was intentionally hit and was neither stabbed or shot, according to news reports.

The Washington Metropolitan Police Department told NBC News on Monday that Officer William Evans was "intentionally struck" Friday afternoon by assailant Noah Green. 

And a police official told the Associated Press that Evans did not appear to have been stabbed, slashed or shot. Police fatally shot the 25-year-old Green after he crashed the vehicle into a metal barrier outside of the Capitol building and lunged at them.

Police released a photo Monday of the wood-handled knife laying on the ground next to an evidence marker.

The second officer who was injured has since been released from the hospital.

Investigators also said they were still attempting to investigate Green's life to find a motive for the attack, NBC also reports.

Green had posted his thoughts on Facebook prior to the events at the Capitol. Some posts alluded to his personal life including one in which he writes about how "hard" the last few years had been for him and on he left his job due to "afflictions." Green was also an avid follower of Louis Farrakhan and the Nation of Islam and wrote several posts on March 17 detailing his beliefs, according the news reports.
