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.
