Officer dead, driver fatally shot after ramming vehicle into barricade near U.S. Capi…

Two law enforcement officials told The Associated Press that the suspect stabbed one of the officers. The officials spoke to AP were not authorized to publicly discuss the pending investigation and spoke on condition of anonymity.

“I just ask that the public continue to keep U.S. Capitol Police and their families in your prayers,” Pittman said. “This has been an extremely difficult time for U.S. Capitol Police after the events of Jan. 6 and now the events that have occurred here today.”

Police identified the slain officer as William “Billy” Evans, an 18-year veteran who was a member of the department’s first responders unit.

Authorities said that there wasn’t an ongoing threat and that the attack did not appear to be related to terrorism, though the Capitol was put on lockdown as a precaution. There was also no immediate connection apparent between Friday’s crash and the Jan. 6 riot.

Law enforcement officials identified the slain suspect as 25-year-old Noah Green. Investigators were digging into the suspect’s background and examining whether he had a mental health history as they tried to discern a motive. They were working to obtain warrants to access his online accounts.

Pittman said the suspect did not appear to have been on the police’s radar. But the attack underscored that the building and campus — and the officers charged with protecting them — remain potential targets for violence.

U.S. President Joe Biden said in a statement that he and his wife were heartbroken to learn of the attack and expressed condolences to Evans’ family. He directed flags at the White House to be lowered to half staff.

The crash and shooting happened at a security checkpoint near the Capitol typically used by senators and staff on weekdays, though most are away from the building during the current recess. The attack occurred about 100 yards (91 metres) from the entrance of the building on the Senate side of the Capitol. One witness, the Rev. Patrick Mahoney, said he was finishing a Good Friday service nearby when he suddenly heard three shots ring out.

The Washington region remains on edge nearly three months after a mob of armed insurrectionists loyal to former president Donald Trump stormed the Capitol as Congress was voting to certify Biden’s presidential win.

Five people died in the Jan. 6 riot, including Capitol Police officer Brian Sicknick, who was among a badly outnumbered force trying to fight off insurrectionists seeking to overturn the election. Authorities installed a tall perimeter fence around the Capitol and for months restricted traffic along the roads closest to the building, but they had begun pulling back some of the emergency measures in recent weeks. Fencing that prevented vehicular traffic near that area was recently removed.

Evans is the seventh Capitol Police member to die in the line of duty in the department’s history. Two officers, one from Capitol Police and another from Washington’s Metropolitan Police Department, died by suicide following the Jan. 6 attack.

Almost 140 Capitol Police officers were wounded then, including officers not issued helmets who sustained head injuries and one officer with cracked ribs, according to the officers’ union. It took hours for the National Guard to arrive, a delay that has driven months of finger-pointing between key decision-makers that day.

Capitol Police and National Guard troops were called upon soon afterward to secure the Capitol during Biden’s inauguration and faced another potential threat in early March linked to conspiracy theories falsely claiming Trump would retake the presidency.

“Today, once again, these heroes risked their lives to protect our Capitol and our Country, with the same extraordinary selflessness and spirit of service seen on January 6,” House Speaker Nancy Pelosi said in a statement. “On behalf of the entire House, we are profoundly grateful.”

The U.S. Capitol complex was placed on lockdown after the shooting and staff were told they could not enter or exit buildings. Video showed National Guard troops mobilizing near the area of the crash.

Video posted online showed a dark-coloured sedan crashed against a vehicle barrier and a police dog inspecting the vehicle. Law enforcement and paramedics could be seen caring for at least one unidentified individual.
