The sister of Miriam Carey, the 34-year-old mother shot dead by police after trying to ram her car through a White House barrier said there was "no need for a gun to be used."
Speaking outside her home in Brooklyn, retired NYPD officer Valarie Carey said there was a police protocol to deal with people suffering from postnatal depression that should have been followed, and that she did not understand why her sister was shot when she was unarmed.
Amy Carey-Jones confirmed her sister had been on medication to help with her postnatal depression, and had endured psychotic episodes.
She said her sister's illness did not impact her loving personality, and said the family had a lot of serious questions over why she was shot dead. Speaking to reporters, alongside her sister Valarie, she said:
"We do not have answers about why they did what they did. They felt she was some particular threat, but Miriam was not firing any shots, there were no weapons, so we are still very confused as a family as to why she is not alive."
"Unfortunately, if people do have moments of crisis, if people do have moments of instability, how do people protect that person? How do they help? How do they operate in a way that contains the situation?"
The female driver who died following a car chase with police near the White House has been named as 34-year-old Miriam Carey from Stamford in Connecticut.
Her former employee at a dental clinic, Dr Barry Weiss, told NBC News she had worked as a dental hygienist and described her as an "average employee".
The Washington Post reports that she graduated from Hostos Community College in the Bronx with an associate's degree in dental hygiene, and appears to have gone on to Brooklyn College to study health and nutrition science.
