Her mother, Eleanor DuBois Schmeer, confirmed that Schmeer was the editor of Academy Award-winning filmmaker Errol Morris's documentaries, including "Fog of War."
Morris tweeted on Saturday about her death, calling it "senseless tragedy."
Police say she was crossing a Manhattan street on Friday night when she was struck by a getaway car fleeing a CVS drugstore where three men had stolen over-the-counter medication.
She was pronounced dead at St. Luke's Hospital.
Police Lt. John Grimpel says the driver was arrested on a murder charge.
