David Burke, the singer known as D4vd, is embroiled in a serious legal battle concerning the murder of 14-year-old Celeste Rivas. During a recent court hearing, prosecutors revealed they discovered a substantial amount of child sexual abuse material on Burke's iPhone, which was seized as part of a broader investigation. The hearing coincided with the one-year anniversary of Rivas' death, which was attributed to 'multiple penetrating injuries' according to the Los Angeles County Coroner’s Office. Burke is accused of engaging in repeated sexual abuse of Rivas over a year, starting when she was as young as 12. Investigators found Rivas' remains in Burke's vehicle, leading to his arrest last week at his home in Hollywood Hills. Burke has pleaded not guilty to all charges and is set to return to court on April 29. Family members of Rivas were present in court, visibly emotional as they processed the details of the case.
