TBD reports that Natasha Pettigrew, a Maryland Green Party candidate for U.S. Senate in Maryland, has died due to injurings she suffered after struck by an SUV while riding her bicycle on Sunday morning on Landover Road in Largo. The story gets even more heartbreaking: the driver, Christy Littleford of Upper Marlboro, did not stop the vehicle after the accident because she thought she had hit an animal; when she got home, Littleford discovered the bicycle under her car and called the police. There are no current charges against Littleford, but Maryland State Police are continuing their investigation.
