STAMFORD, Conn. (October 4, 2013)—Miriam Carey, 34, whom officers shot to death Thursday after a chase from the White House to Capitol Hill, was fired from her job as a dental hygienist about a year ago, periodontist Brian Evans of Hamden, Conn., said.
Evans said Carey had been a good employee and said Friday there was nothing unusual about her departure, but he declined to go into further detail.
He said Carey left the office shortly after she was hospitalized with a head injury she suffered in a fall down a staircase.
Carey’s mother was her daughter had suffered from post-partum depression after the death of her 1-year-old daughter, who was with Carey in the car Thursday.
The infant wasn’t injured.
Carey's mother, Idella Carey, told ABC News her daughter began suffering from post-partum depression after having her daughter, Erica, last August.
"She was depressed," Idella Carey said.
The mother says her daughter had "no history of violence" and she didn't know why she was in Washington, D.C.
A federal law enforcement official told The Associated Press Friday that Carey believed the president was communicating with her and was delusional.
The official, who had been briefed about the investigation and spoke on condition of anonymity, said Carey had been in a deteriorating mental state since December.
