Sister of Driver in DC Chase: 'Impossible' Though mom says she had post-partum depression By Matt Cantor, Newser User Posted Oct 4, 2013 4:25 AM CDT Updated Oct 4, 2013 7:55 AM CDT 118 comments Comments Emergency response vehicles wait outside the apartment complex where Miriam Carey is believed to have lived in Stamford, Conn. Thursday, Oct. 3, 2013. (AP Photo/John Minchillo) (Newser) – Those who knew Miriam Carey, the reported driver of the black Infiniti at the center of yesterday's DC chase, are struggling to believe the news. "That’s impossible. She works, she holds a job," sister Amy Carey tells the Washington Post. "She wouldn’t be in DC. She was just in Connecticut two days ago," though she does have a black car, Amy says. But Carey's mom, Idella, tells ABC News her daughter was suffering from post-partum depression. Miriam gave birth to her daughter last August, Idella Carey says, and "a few months later, she got sick. She was depressed. ... She was hospitalized." (Police confirmed a 1-year-old girl was in the car with Carey when she was killed.) A former classmate says Miriam Carey "was really just a sweet and nurturing person," and a college friend says Carey was "always very professional" and "very focused." She didn't discuss politics, and wasn't one to lose her temper. But DC police chief Cathy Lanier says the situation yesterday didn't seem to be an accident. The Connecticut Post notes that Carey had no criminal record. Now her neighborhood in Stamford, Conn., is flooded with officials: "A full investigation is underway by federal authorities," says the city's mayor. A few more details have emerged: Carey—or someone with the same name—got a BA in health and nutrition from Brooklyn College in 2007. She also had an associate degree in dental hygiene from the Bronx's Hostos Community College. She moved to Stamford in 2009 after living in Brooklyn, close to her family, for years. In 2002, she gained a dental hygiene license from New York state; in 2009, she got one from Connecticut. She ran a temping business out of her Connecticut condo called Experienced Dental Placements. Her condo association sued her last year for unknown reasons, but the suit was dropped. BuzzFeed has an account of what's known so far, with photos.
