One U.S. Capitol Police officer was killed and another injured when a man identified as 25-year-old Noah R. Green, of Indiana, rammed a vehicle into them at a barricade outside the Capitol building in Washington, DC. Officer William “Billy” Evans was the officer killed. He had been with the police force for 18-years. Green, an African American man, was not on any watch lists and appeared to have acted alone, sources say. Social media posts by Green suggest anti-government sentiments played a role in his actions. Other experts say mental health issues were at play as well.
