More details are coming out via a private investigator in the ongoing D4vd case in the death of Celeste Rivas. A private investigator looking into the death of 15-year-old Celeste Rivas says he discovered unusual tools in D4vd’s former rental home in the Hollywood Hills. In a new interview, Los Angeles-based investigator Steve Fischer, who was hired by the owner of the home where D4vd had been living, told the Daily Mail: ”There were multiple of these items that could all be used together – heavy-duty tools and machinery you’d never need in a Hollywood Hills home. You’d be more likely to find them on a farm.
