PITTSBURGH (AP) — The funeral service is scheduled Tuesday for an off-duty Pittsburgh police officer shot to death in a street confrontation more than a week ago. Thirty-five-year-old Officer Calvin Hall died Wednesday, three days after he was shot three times in the back during a street dispute in the Homewood neighborhood as a party was going on. Police announced a criminal homicide charge against a suspect Monday as a viewing for the slain officer was being held.
