Las Vegas police are questioning a man found covered in blood at a home where a 9-year-old boy told school officials his mother and sister were dead. Officer Marcus Martin told The Associated Press on Monday that police arriving about 9 a.m. found two people down inside the house in the West Las Vegas neighborhood. Another young child was also inside. It's not clear if that child is hurt. No further details were available. Martin says the 9-year-old boy told officials at nearby Hoggard Elementary School about the scene at a house.
