Authorities identify man who rammed car into Capitol Police as Nation of Islam follower; officer killed in attack is also identified

Law enforcement authorities released the identity of a 25-year-old man who was shot and killed after ramming his car into U.S. Capitol Police officers on Friday, killing one and seriously injuring another.

NBC's Pete Williams reported that police had identified the man as Noah Green, an "unemployed" man from Indiana. He added that the man's Facebook page identified him as a follower of the Nation of Islam.

The Capitol Police also released the identity of the officer who was killed in the attack as William "Billy" Evans. He was an 18-year veteran of the force.

Capitol Police said that Green was driving a blue sedan when he rammed two Capitol officers near the north barricade at the U.S. Capitol. He then exited the vehicle and ran toward other officers with a knife. At least one officer shot at him and he later died at a hospital.

D.C. Metropolitan Police Chief Robert J. Contee III said that the incident did not appear to be terrorism related, and that there was no ongoing threat.The Facebook page of the suspect said that he had recently lost his job.

In a recent post documented by Mediaite, he wrote a religious message related to the Nation of Islam.

"Peace, friends, family, enemies, and the like," Green wrote in March. "To be honest these past few years have been tough, and these past few months have been tougher. I have been tried with some of the biggest, unimaginable tests in my life. I am currently now unemployed after I left my job partly due to afflictions, but ultimately, in search of a spiritual journey."

That Facebook page was quickly scrubbed from the internet after many circulated screenshots.

The Capitol complex was locked down after the incident but was later opened back up. National Guard troops moved in to secure some areas at the Capitol.
