Evans’ death was ruled a homicide, according to a statement from the medical examiner’s office.
Evans, an 18-year veteran of the Capitol Police, died while protecting the Capitol from a man who brandished a knife after ramming his car into a police barricade along the perimeter of the Capitol. Another officer was injured in the attack.
DC Police said Noah Green, 25, rammed a blue sedan into Evans and another officer, who was injured, last Friday shortly before 1 p.m.
After crashing into a security gate, police say, Green got out of the car with a large knife and a third officer shot him when he lunged at the officer.
Green later died at a hospital.
