Prosecutors at Burke's preliminary hearing presented forensic evidence from Burke's Hollywood Hills home and the Tesla's front trunk where Celeste Rivas Hernandez's remains were found. LAPD witnesses described BLUESTAR testing indicating possible blood on garage floor mats, a green tarp, a damaged pool, and a stained trash bag. Chainsaws tested negative for blood, raising questions about where DNA or other evidence may come from. Investigators noted odors and maggots in the Tesla trunk and other items that fit a narrative of dismemberment. Burke's defense argued about limitations of DNA testing and possible touch DNA, noting multiple people lived at the residence and some items showed no definitive blood. The hearing is expected to run several days with more than 10 witnesses, and prosecutors may seek the death penalty; Burke remains charged with murder, sexual abuse of a minor, and mutilation, with Celeste Rivas Hernandez identified as 14 at the time of her death.
