Mom Says Woman in Capitol Chase Had Post-Partum Depression

Motive for behavior still unknown

The 34-year-old Connecticut woman who was shot and killed by police after a harrowing high-speed chase from the White House to Capitol Hill suffered from post-partum depression, her mother told ABC News.

Miriam Carey, a dental hygienist from Stamford, Conn., was identified as the driver of the black luxury sedan that first rammed a barrier at the White House, then sped to Capitol Hill, defying attempts by armed police to stop her Thursday afternoon. She was shot and killed fleeing her car near the Hart Senate Office Building

Afterward, police discovered Carey's 1-year-old daughter was in the backseat of her black Infiniti throughout the ordeal. The child, who was not injured, was taken to a hospital for a precaution and placed in protective custody.
