@cbsmornings: Replying to @CBS Mornings A 15-year-old boy suspected of killing his parents and three of his siblings called 911 and said his younger brother shot his family before killing himself, court documents show. But that was before a second 911 call came in from a neighbor, who had been told by a surviving sibling, an 11-year-old girl, that her 15-year-old brother used their father’s gun. #washington #crime
