(Obtained by ABC News)(NEW YORK) — A 95-year-old woman is being held at Rikers on charges accusing her of beating her roommate to death at their Brooklyn nursing home. Kravtsov sustained fractures to her face and head, and she died early Monday morning due to blunt force trauma, according to the medical examiner’s office. The murder weapon appeared to be a blood-stained wheelchair foot pedal seen lying on the floor, the Brooklyn District Attorney’s office said. ABC News has reached out to Smirnova’s lawyer and Seagate Rehabilitation and Nursing Center for a comment.
