PITTSBURGH—A 70-year-old woman injured by a hit-and-run driver outside a Pittsburgh fast-food restaurant last week has died.

The Allegheny County medical examiner says Estelle Cepek, of Blawnox, died Sunday night at UPMC Presbyterian hospital.

She had been there since she was hit by what police believe was a dark-colored pickup truck in the parking lot of a McDonald's restaurant in the city's East Liberty section about 7:15 a.m. Wednesday.

Police say Cepek was originally listed in fair condition and expected to survive before doctors discovered broken bones and other internal injuries.

The victim volunteered by answering calls at a behavioral health center near the restaurant where she walked to get her morning coffee each day.

Police have yet to charge or identify the driver.
