Watch Woman Shot and Killed by Capitol Police After Chaotic Chase from White House

After attempting to ram down the gates to the White House, Miriam Carey, 34, a dental hygienist who once lived in Brooklyn led Secret Service agents and police on a pursuit toward the U.S. Capitol where she was gunned down. The chaos temporarily put the U.S. Capitol in lockdown.

A crazed Connecticut woman who tried to ram her way into the White House was shot and killed Thursday after she led police on a high-speed chase through the heart of Washington that left two police officers injured.

Miriam Carey, a 34-year-old dental hygienist from Stamford who once lived in Brooklyn, had a year-old child in the car with her who was not hurt, officials said.

'This appears to be an isolated incident,' said Capitol Police Chief Kim Dine. 'There is no nexus to terrorism.'

ABC News reported the woman had a history of 'mental health issues.'

The drama began around 2:20 p.m., officials said, after Carey --- driving a leased black Infiniti -- sped into the driveway leading into the White House and tried to breach security at 15th and E Streets, officials said.

Thwarted by the pylons and confronted by cops with their guns drawn, Carey spun the car around and hit the gas -- knocking a Secret Service agent over the hood of the car as she sped away.
