A woman driving a black Infiniti with a young child inside tried to ram through a White House barricade Thursday, then led police on a chase toward the Capitol, where police shot and killed her, witnesses and officials said.

Tourists watched the shooting unfold on Constitution Avenue outside the Capitol as lawmakers inside debated how to end a government shutdown. Police quickly locked down the entire complex temporarily, and both houses of Congress went into recess.

UPDATE 7:25 p.m. ET: Via the Hartford Courant:

A Stamford dental hygienist with a history of mental health issues was killed after a chase and shooting near the U.S. Capitol on Thursday, a source with knowledge of the investigation said.

The source said Miriam Carey, 34, was the woman who was driving the black Infiniti coupe with Connecticut license plates that tried to pass a security check point at the White House, led police on a chase through central Washington and died after being shot near the U.S. Capitol.

UPDATE 6:06 p.m. ET: Police would not reveal any information on the female suspect, but they did confirm that she has been “pronounced” dead.

There were two officers injured during the pursuit, and both are in good condition, police said.

The child who was traveling in the suspect’s car is reportedly in protective custody.

UPDATE 5:35 p.m. ET: The Washington Posts says that the suspect involved in the incident was a woman in her 30s and that a child taken from the car could be as young as one. The Post also cites two sources who say the woman did not have a gun.

Rep. Michael McCaul (R-Texas) told Fox News the woman was “African-American.”

UPDATE 5:15 p.m. ET: Eyewitnesses describe the frantic scene in the aftermath of the incident.

“I didn’t really have time to think; if I had I probably wouldn’t have gone outside,” one witness told TheBlaze’s Oliver Darcy.

“I really didn’t know what to think. I heard the seven or eight shots. There were dozens of officers. So much so that you really couldn’t even see what was happening. There were officers in police vehicles on every side, swarming, and more coming in every second.”

UPDATE 4:25 p.m. ET: New video of the black car involved in the incident has emerged:

UPDATE 4:05 p.m. ET: Executive Director of the American Center for Law and Justice Jordan Sekulow witnessed some of the chaos that unfolded on Thursday and recalled the surreal incident in an interview with TheBlaze.

Sekulow says he could see the crime scene outside his office window in Washington, D.C. He also said there were sirens before gun shots rang out.

“Then we hear, ‘boom, boom, boom!’ and someone said, ‘that’s gunfire, everybody needs to get down,’” he recalled. “There was what I can only describe as an army of police responding at what is literally our intersection.”

UPDATE 4:00 p.m. ET: New video obtained by NBC News shows people running away after shots were fired outside the U.S. Capitol on Thursday.

UPDATE 3:51 p.m. ET: Sergeant at Arms Terrance Gainer is now telling a local Fox affiliate that the incident split into two locations. In other words, there are two crime scenes that police are investigating.

That seems to be corroborated by TheBlaze’s own Oliver Darcy, who reports Capitol Police have told him they have “multiple crime scenes.”

Gainer said there were shots fired at both locations and the suspect sped away from the first incident and fled to the second crime scene.

Reports indicate that the female suspect rammed a security barricade near the White House before speeding away and being stopped by police at the second crime scene.

UPDATE 3:44 p.m. ET: TheBlaze’s Oliver Darcy reports live from Washington, D.C.:

UPDATE 3:30 p.m. ET: Sergeant at Arms Terrance Gainer told a local Fox affiliate that the incident does not appear to be related to terrorism and is believed to be an isolated incident.

He also said it appears that shots were fired by law enforcement. It’s unclear if the suspect involved in the incident ever fired shots or if all shots were fired by police.

The child who was reportedly in the suspect’s car was taken to the hospital but she was not believed to be injured, Gainer said.

During a press conference, the police chief said it appears that no officers were shot in the incident. Injuries sustained by one officer after reportedly being struck in his squad car are not believed to be life threatening.

The police chief did not have an update on the female suspect’s condition.

UPDATE 3:24 p.m. ET: TheBlaze’s Oliver Darcy is on the scene at the U.S. Capitol. We will continue bringing you breaking updates.

en. Bob Casey, D-Pa., told reporters he was walking from the Capitol to the Senate Russell Office Building across the street when he noticed several police officers driving fast up Constitution Avenue on motorcycles.

“Within seconds of that,” Casey said, “we heard three, four, five pops,” which he assumed were gunshots. He said police ordered Casey and nearby tourists to crouch behind a car for protection.

In about two minutes, he said, the officers moved everyone into the Capitol.

FBI agents rushed to the scene and Senate Sergeant at Arms Terrance Gainer confirmed: “There are reports of injuries.”
