STAMFORD - The family of the Stamford woman who was shot to death by police in Washington D.C is asking for a federal investigation.

Miriam Carey, 34, was shot by officers on Capitol Hill in October when she rammed a White House barricade, hit a police car and refused to stop.

A lawyer representing Carey's family has sent a letter to the U.S. Attorney General claiming police violated Carey's civil rights and used excessive force.

Police records show before the incident, her boyfriend had expressed concern about her emotional stability and she had told officers she thought President Obama was watching her.
