Singer D4vd has lost his private lawyers and entered a new not guilty plea. He's facing charges of murder, sexual abuse and dismemberment of 14-year-old Celeste Rivas Hernandez. It's not clear why his high-profile attorneys, Blair Berk and her colleagues, withdrew. They were replaced by a public defender. The judge on Monday denied a request from the public defender to delay the arraignment and scheduled a status conference for October. Despite earning millions from his music, the indie-pop singer, born David Burke, qualified for a court-appointed lawyer. A trial date has not been set.
