Members of the CCSO Traffic Operations Unit are investigating a crash that killed a woman. On Thursday, November 24 at 6:30 p.m., the driver of a Chevy Equinox failed to yield the right of way while attempting to make a left turn from westbound Billingsley Road onto southbound St Charles Parkway. Her vehicle was struck by a Mercedes which was traveling east on Billingsley Road. Three people in the Equinox were seriously injured: The driver – a 46-year-old woman, and a front seat passenger – were flown to a hospital where the passenger, Sherry Lynn Bunnell, 46, of Mechanicsville, died the following day. A woman in the backseat of the Equinox was transported to a local hospital with injuries that were not life-threatening. The driver of the Mercedes, a 43-year-old male from Waldorf, was treated on the scene. Cpl. B. Saunders is continuing the investigation.
