WASHINGTON (NBC/ WSAZ) - Officials say a suspect that fired shots outside the U.S. Capitol building has been killed.
Police say the incident started at the White House Thursday. The female suspect rammed her car into the gate but failed to smash her way through. Police say after that attempt, she headed for the U.S. Capitol.
The Capitol Building and the six Senate and House buildings were ordered locked down. Lawmakers and staffers were told to shelter in their offices.
A confrontation between the suspect and police ended with gunshots near the west side of the Capitol. Then the suspect lead officers on a car chase, with a child inside.
The chase ended with a crash that injured a police officer. Police say he was not shot. The suspect was taken into custody but suffered from gunshot wounds. She is now dead.
The alert in Washington was lifted. All congressional buildings have reopened.
A law enforcement official says a shooting is related to a vehicle that tried to ram a security barricade at the White House.
The official says a driver tried to drive through a barricade that blocks the stretch of Pennsylvania Avenue in front of the White House to vehicles. The driver then proceeded down Pennsylvania Avenue to Capitol Hill, where shots were fired.
A tourist who was outside the building says the shooting unfolded after police chased a car up Constitution Avenue toward the Capitol. He says he "heard the gunfire" and hit the ground.
Senator Bob Casey of Pennsylvania says he was walking from the Capitol to a Senate office building when he noticed several police officers riding quickly up Constitution Avenue on motorcycles. He says he then heard three to five "pops" -- and that officers soon moved everyone into the Capitol building.
As a warning was sounded, the House went into recess. The Senate also suspended business.
The House had just approved legislation aimed at partly lifting the government shutdown by paying National Guard and Reserve members.
