I am sure you have seen this before, it’s over the screens and newspapers here and there. Yet, some will still need to know more about it. The latest news about Connecticut mother (Miriam Carey) gunned down by the police on Thursday after ramming at White House barrier with her young daughter in the car with her.

She thought President Obama was stalking her, law sources said yesterday.

Investigation has revealed that she suffered delusions due to a history of mental illness. Daily mail reports that;

She believed the President was electronically monitoring her Connecticut home in order to broadcast her life on television, sources said.

ABC News reports that Connecticut police had twice in 2012 been called by Miriam Carey's boyfriend, who reported the woman was delusional, acting irrationally and putting her infant daughter in danger.

Last night her mother revealed the 34-year-old has suffered from postpartum depression since giving birth to her daughter Erica last year.

These revelations are the first clues as to what led a seemingly happy dental hygienist to snap and drive her Infiniti luxury sedan 270 miles from her home in suburban Stamford to Washington, DC - where her rampage put the nation's capital on lock-down Thursday.

Carey's 18-month-old daughter Erica - who was in the back seat - was not injured, despite the Secret Service and U.S. Capitol police firing up to 15 shots into her car.

Little Erica was rescued from the bullet-riddled car after her mother was shot dead. She is currently in the custody of child services workers.

It emerged today that Carey had been sued by her condominium association for failure to pay fees.
