Days after music star D4vd was arrested on suspicion of murder, authorities formally charged the singer - real name David Anthony Burke - with murder, repeated s***** abuse of a minor and mutilation of human remains in connection with the death of 14-year-old Celeste Rivas Hernandez, the Los Angeles County District Attorney's Office confirmed. D4vd, 21, has pleaded not guilty to the charges. "Celeste was just a child, under 14 years old, when David Burke allegedly engaged in repeated lewd and lascivious s***** relations with her," District Attorney Nathan Hochman said.
