FBI agents in Stamford, Conn., are searching for clues about why an unarmed 34-year-old mother who lived there went on a driving rampage in Washington, D.C. yesterday.
The incident resulted in her shooting death by Capitol police.
Miriam Carey was traveling with her 1-year-old daughter when she tried to breach a barrier at the White House, and then veered her car down Constitution Avenue, driving up to 80-miles-per-hour, toward the Capitol buildings. She eventually crashed into a barrier.
The incident caused a temporary lock-down at the Capitol, where lawmakers were debating measures to end the government shutdown.
Carey's mother told ABC News last night that her daughter had been suffering from postpartum depression.
