Thursday afternoon, a woman was shot and killed after she allegedly rammed into barricades near the White House and then led police on a chase toward the U.S. Capitol building.
Law enforcement sources have identified the driver of the car as Miriam Carey, a 34-year-old dental hygenist with a history of mental illness.
A motive for Carey has yet to be released but Capitol Police Chief Kim Dine told reporters they did not believe it to be an act of terrorism.
A Facebook matching Carey's description being circulated online offers few clues as to why Carey chose to drive into a security barricade.
Carey's daughter was in the car when it crashed after her chase with Capitol Police, but she was uninjured. She is believed to be between 2 or 3 years old.
After Carey was identified, Stamford police descended upon her home in Connecticut.
According to the Stamford Advocate, police brought a bomb squad with them.
Update — Oct. 3, 11 p.m. ET: Family spokesman confirms the name of the suspect is Miriam Carey.
The Washington Post reports Carey had postpartum depression:
"She had post-partum depression after having the baby" last August, said the woman's mother, Idella Carey.
She added, "A few months later, she got sick. She was depressed. ... She was hospitalized."
