Two of the sisters of the driver killed in a hail of gunfire after a high-speed chase from the White House to U.S. Capitol talked exclusively to Anderson Cooper.  Miriam Carey’s sisters, Valarie and Amy, both said she did experience post-partum depression with psychosis, but was not battling schizophrenia or bipolar disorder. Their sister’s one-year-old daughter was in the car during Thursday’s chase, but was unharmed in the chaos.  Both sisters said Miriam was a “nurturing mother” and wonderful person. They also told Anderson they didn’t know she was in Washington and are still in “shock” over the incident.  They said they have a lot of questions about what happened to Miriam.  A lot of things “just don’t add up,” said Amy.  In this exclusive interview, Carey’s sisters share their fond memories of her, give details on her mental state and vow to seek answers to why “she’s not alive to be with her family.”

Watch part two of the interview:

Today's shooting happened in the middle of a government shutdown. That means many of the authorities on Capitol Hill were working without a paycheck. Tom Fuentes is a former top FBI official, and he spoke to Anderson about how law enforcement handled the situation, and whether their actions were correct in this situation.

The shooting on Capitol Hill happened in front of thousands of people, including Patty Bills and Matthew Coursen. They both witnessed the panic and chaos as bullets flew in the nation's capital.
