The 18-year U.S. Capitol Police veteran killed in the line of duty is being remembered as a man with a sense of humor who loved baseball and golf and was most proud of one particular title: Dad.

William “Billy” Evans, 41, was killed Friday when a vehicle rammed into Evans and another officer at a barricade just 100 yards from the Capitol. The driver, Noah Green, 25, came out of the car with a knife and was shot to death by police, officials said. Investigators believe Green had been delusional and increasingly having suicidal thoughts. Capitol Police released few personal details about Evans, saying his family had requested privacy.
