WASHINGTON (WJLA) - The emerging picture of Miriam Carey, the woman responsible for Thursday's high speed chase that injured two police officers with her 1-year-old daughter in the car, is of a 34-year-old whose life was coming apart as her mental health deteriorated.

Last December, Carey's then-boyfriend, the father of her daughter Erika, told Stamford, Conn., police that he was afraid for the baby's safety.

Carey apparently believed President Obama had placed her on lockdown and put her home under electronic surveillance.

"She had a wonderful life. I don't understand it. It doesn't make any sense at all," said family friend, Yolanda Napoleon.

A friend had also just seen her this past Tuesday.

"Everything was okay," said Donald Knowles. "Hi, a little joke, and she went about her business."

Twice in two weeks, she was taken to the hospital for a mental evaluation. CNN reports the search of her Stamford apartment turned up medication to treat schizophrenia and bipolar disorder in addition to an anti-depressant.

Carey's mother, Idella Carey, told ABC News on Thursday night that her daughter began suffering from post-partum depression after giving birth to her daughter, Erica, last August.

"A few months later, she got sick," she said. "She was depressed. ... She was hospitalized."

Idella Carey said her daughter had "no history of violence" and she didn't know why she was in Washington on Thursday. She said she thought Carey was taking Erica to a doctor's appointment in Connecticut.

Police said there appeared to be no direct link to terrorism and there was no indication the woman was even armed. Capitol Police Chief Kim Dine, whose officers have been working without pay as a result of the shutdown, called it an "isolated, singular matter."
