WASHINGTON (AP) - A woman with a 1-year-old girl led Secret Service and police on a harrowing car chase from the White House past the Capitol Thursday, attempting to penetrate the security barriers at both national landmarks before she was shot to death, police said. The child was unhurt.

"I'm pretty confident this was not an accident," said Metropolitan Police Chief Cathy Lanier. Still, Capitol Police said there appeared to be no terrorist link. The woman apparently was unarmed.

Tourists, congressional staff and even some senators watched as a caravan of law enforcement vehicles chased a black Infiniti with Connecticut license plates down Constitution Avenue outside the Capitol. House and Senate lawmakers, inside debating how to end a government shutdown, briefly shuttered their chambers as Capitol Police shut down the building.

The woman's car at one point had been surrounded by police cars and she managed to escape, careening around a traffic circle and past the north side of the Capitol. Video shot by a TV camerman showed police pointing firearms at her car before she rammed a Secret Service vehicle and continued driving. Lanier said police shot and killed her a block northeast of the historic building.

One Secret Service member and a 23-year veteran of the Capitol Police were injured. Officials said they are in good condition and expected to recover.

"This appears to be an isolated, singular matter, with, at this point, no nexus to terrorism," said Capitol Police Chief Kim Dine.

Law-enforcement authorities identified the woman as Miriam Carey, 34, of Stamford, Conn. The authorities spoke on condition of anonymity because they were not authorized to divulge the information publicly.

Stamford Mayor Michael Pavia said the FBI was executing a search warrant at a Stamford address in connection with the investigation. Police officers had cordoned off a condominium building and the surrounding neighborhood in the shoreline city.

The pursuit began when the car sped onto a driveway leading to the White House, over a set of lowered barricades. When the driver couldn't get through a second barrier, she spun the car in the opposite direction, flipping a Secret Service officer over the hood of the car as she sped away, said B.J. Campbell, a tourist from Portland, Ore.

Then the chase began.

"The car was trying to get away. But it was going over the median and over the curb," said Matthew Coursen, who was watching from a cab window when the Infiniti sped by him. "The car got boxed in and that's when I saw an officer of some kind draw his weapon and fire shots into the car."

Police shot and killed the driver just outside the Hart Senate Office Building, where many senators have their offices. Dine said an officer took the child from the car to a hospital. She was not injured and was placed in protective custody, Capitol Police said.

Rep. Michael McCaul, R-Texas, who said he was briefed by the Homeland Security Department, said he did not think the woman was armed. "There was no return fire," he said.

A few senators between the Capitol and their office buildings said they heard the shots.

"We heard three, four, five pops," said Sen. Bob Casey, D-Pa. Police ordered Casey and nearby tourists to crouch behind a car for protection, then hustled everyone into the Capitol.

Others witnessed the incident, too.

"There were multiple shots fired and the air was filled with gunpowder," said Berin Szoka, whose office at a technology think tank overlooks the shooting scene.

The shooting comes two weeks after a mentally disturbed employee terrorized the Navy Yard with a shotgun, leaving 13 people dead including the gunman.

Before the disruption, lawmakers had been trying to find common ground to end a government shutdown. The House had just finished approving legislation aimed at partly lifting the government shutdown by paying National Guard and Reserve members.

Capitol Police on the plaza around the Capitol said they were working without pay as the result of the shutdown.

WASHINGTON (AP) - A woman driving a black Lexus tried to ram through a White House barricade Thursday, then led police on a chase that ended in gunfire outside the Capitol, 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 for about an hour, and both houses of Congress went into recess.

The pursuit began when a car tried to ram a security barricade blocking the stretch of Pennsylvania Avenue in front of the White House, according to a law enforcement official who was not authorized to discuss the case by name and insisted on anonymity.

Witnesses said at least 20 police cars chased the Lexus toward Capitol Hill, where the car crashed outside the Capitol.

Tourist Edmund Ofori-Attah said he walked toward the scene, curious about what was going on.

"Then I heard the gunfire" and hit the ground, he said.

Senate Sergeant at Arms Terrance Gainer said a woman was driving the car and had a child with her. Ofori-Attah said the child appeared to be about 2 to 3 years old.

Gainer said the child was taken to a hospital.

Capitol Police Chief Kim Dine said the driver was in custody. He did not disclose her condition.

A police officer was injured in the traffic accident but Gainer said the injuries were not life threatening.

"We heard three, four, five pops," said Sen. Bob Casey, D-Pa., who was walking from the Capitol to an office building across the street. Police ordered Casey and nearby tourists to crouch behind a car for protection, then hustled everyone into the Capitol.

"There were multiple shots fired and the air was filled with gunpowder," said Berin Szoka, whose office at a technology think tank overlooks the shooting scene.

The shooting comes two weeks after a mentally disturbed employee terrorized the Navy Yard with a shotgun, leaving 13 people dead including the gunman.

Before the disruption, lawmakers had been trying to find common ground to end a government shutdown. The House had just finished approving legislation aimed at partly lifting the government shutdown by paying National Guard and Reserve members.

People standing outside the Supreme Court across the street from Congress were hurried into the court building by authorities.

The White House also was briefly locked down after the incident at Capitol Hill and the stretch of Pennsylvania Avenue in front of the compound was closed to pedestrians. Secret Service said the procedures were precautionary.
