State authorities have taken over the investigation into the death of a woman who was struck by a car and killed after an argument with her boyfriend, a former Bucks County prosecutor.
Richard Patton, 51, of New Hope, previously worked as an assistant prosecutor for the county and for the state Attorney General's Office.
Patton was driving the car that struck Heather Demou, 34, a real estate agent from Doylestown, after the two argued Thursday outside a Newtown restaurant, police said.
According to police, Patton told them Demou stepped in front of the car to stop him from leaving. Toxicology and other tests are pending, and he has not been charged, authorities said.
