STAMFORD (PIX11) – Less than a day after Miriam Carey and her black Infiniti sports car forced the nation’s capital to go from shutdown to lockdown, the focus is now on the 34-year-old dental hygienist’s state of mind.

Her mother told ABC News that her daughter suffered from postpartum depression.  Carey’s one-year-old daughter was with her inside the vehicle when she fled from Capitol Hill police and was ultimately shot dead.

This as new reports from law enforcement officials that Carey believed she was being stalked by President Barack Obama, who she believed was feeding footage from inside her home to national news outlets.

Erica Jackson was Carey’s next door neighbor.  She could not believe that Carey was behind the wheel or may have been suffering from depression.

Meanwhile in Brooklyn, the NYPD was stationed outside the entrance to the Pink Houses along Stanley Avenue in Brooklyn.  Community Affairs officers paid a visit to the unit belonging to Carey’s mother on the second floor.

They left in a matter of minutes.

Whether or not postpartum depression or psychosis may have played a role remains a mystery.  PIX 11 News very own Dr. Steve discussed how psychosis impacts a person’s psyche on the PIX11 Morning News as, “Where you develop confusion, disorientations, hallucinations, delusions, paranoia or attempts to harm yourself or your baby.”
