@cbsnews: Singer D4vd pleaded not guilty to charges including murder in downtown Los Angeles on Monday in connection with last year's killing of 14-year-old Celeste Rivas Hernandez as the high-profile case progresses to a trial. The 21-year-old, whose real name is David Anthony Burke, will now be represented by public defenders after his defense team withdrew from the case Monday morning. The reason for their withdrawal is not yet clear. LA County District Attorney Nathan Hochman said his office is working to determine whether it will pursue the death penalty should Burke be convicted. #news #d4vd #crime #court #losangeles
