A maniac slammed his car into two US Capitol Police officers on Friday afternoon — killing one — before he was shot dead by police while running at them with a knife, officials said.
The mayhem — which one high-ranking cop called “senseless” — erupted shortly after 1 p.m., sending the government building into lockdown and drawing a massive response from law enforcement authorities and the National Guard.
The slain cop was identified by the Capitol Police as William “Billy” Evans, an 18-year veteran of the force.
His killing came less than three months after the deadly Capitol riot in which a fellow officer, Brian Sicknick, was among five fatalities.
The driver was identified as Noah Green, 25, of Indiana, according to NBC News, which cited four law enforcement officials briefed on the matter.
Green died after being taken to a hospital, as were the two cops mowed down.
Acting Capitol Police Chief Yogananda Pittman appeared to struggle with her emotions as she revealed one of the cops had died.
“It is with a very, very heavy heart that I announce that one of our officers has succumbed to his injuries,” Pittman said during a news conference.
At the time, Pittman said she couldn’t yet identify the slain cop “because we still have to notify the next of kin.”
“This has been an extremely difficult time for US Capitol Police after the events of Jan. 6 and now the events that have occurred here today,” she said.
“So I ask that you keep our US Capitol Police family in your thoughts and prayers.”
A tweet from the Capitol Police posted before Evans was identified said that he died at 1:30 p.m.
“At least one officer drew their weapon and shot the suspect,” the statement added.
The fatal attack “does not appear to be terrorism-related but obviously, we’ll continue to investigate to see along those lines,” acting Washington, DC, Metropolitan Police Chief Robert Contee said.
Contee also said there “does not appear to be an ongoing threat.”
“Obviously, we’re in the very early stages of our investigation,” he said.
“We need to obviously understand the motivation behind this senseless act. So the Metropolitan Police Department will certainly be doing that.”
The suspect doesn’t appear to be anyone with whom cops are familiar and there’s “no indication” he was targeting any member of Congress, Pittman said.
Both the Senate and the House of Representatives are currently in recess for the Easter holiday.
The lockdown of the Capitol was lifted shortly after 3 p.m.
The incident took place at a vehicle checkpoint on the north side of the Capitol along Constitution Avenue in Washington DC, that’s about 100 feet from an entrance on the Senate side.
Pittman said authorities were reviewing surveillance video.
“The suspect did exit the vehicle with a knife in hand. And at that time he started to lunge toward — run aggressively toward US Capitol police officers,” she said.
A photo of the scene taken shortly after the incident shows a dark blue sedan with its front end crumpled against a white metal, pop-up barricade with the words “STOP” in red.
The driver’s door and trunk were also open as authorities gathered around a band of yellow caution tape.
A 12-foot fence, topped with razor wire, was erected around the Capitol to restrict access and block traffic following the Jan. 6 riot.
But it was taken down about a month ago and replaced with a shorter, 8-foot fence that pulled in the perimeter and allowed vehicles to pass by.
