Singer D4vd, pronounced “David,” is about to face a preliminary hearing where a judge will decide whether he should go to trial in connection with the killing and dismembering of 14-year-old Celeste Rivas Hernandez. At the hearing planned for Friday, witnesses will be called and evidence will be presented. Lawyers for the 21-year-old singer whose legal name is David Anthony Burke say he is not guilty. Rivas Hernandez's body was discovered in a towed Tesla registered to Burke in the Hollywood Hills last year. He has been charged with first-degree murder and other felony counts.
