Day 4 of the D4vd, aka David Anthony Burke, preliminary hearing was the most disturbing day of testimony so far. There were audible gasps in the courtroom as the medical examiner showed photos from the autopsy of 14-year-old Celeste Rivas Hernandez, detailing how the young teen was stabbed twice and then dismembered. We also heard testimony from a police detective who went over the sexually graphic and explicit photos and videos between D4vd and Celeste, including text messages describing at least one pregnancy and abortion.
