Gregory Gray, a 21-year-old Mt. Hope resident will be arraigned tonight on charges that he caused the death of an 8-week-old baby girl. Although, the baby's last name is also Gray and her residence is the same as Gregory Gray's, the Bronx District Attorney's office could not confirm whether she was his child. Gray is facing manslaughter charges after the medical examiner's office ruled Demi Gray's death a homicide. Demi died on Wednesday after being taken to St. Barnabas hospital.
