Evans died while another police officer was hospitalized after a car crashed into a security barrier at the US Capitol complex after which the driver lunged towards the officers with a knife. The officers opened fire and the suspect was shot dead.
“Officer Evans, his family, and all those who knew him are in our hearts and prayers. We mourn with them during this difficult time,” the US vice president said in a statement.
“Doug and I are grateful for the Capitol Police, the National Guard Immediate Response Force, and everyone else who responded swiftly to today’s attack,” Harris, who served in the Senate for four years, said.
“And we continue to be proud of the courageous men and women who defend the Capitol, especially during a challenging period when they have faced two violent and deadly attacks,” she said.
Harris also said, “In an inexplicable act of violence, a brave US Capitol Police Officer, William Evans, was killed in the line of duty while another officer fights for his life. Officer Evans made the ultimate sacrifice to protect the Capitol. Our hearts go out to his family and loved ones.”
Earlier on Friday, the White House flag was lowered to half-staff following the death of the the 18-year US Capitol Police veteran.
US President Joe Biden reacted to the incident, saying he and first lady Jill Biden were heartbroken.
“Jill and I were heartbroken to learn of the violent attack at a security checkpoint on the US Capitol grounds, which killed Officer William Evans of the US Capitol Police, and left a fellow officer fighting for his life,” Biden said.
“We send our heartfelt condolences to Officer Evans’ family, and everyone grieving his loss. We know what a difficult time this has been for the Capitol, everyone who works there, and those who protect it,” the President said.
