The court reverses defendant's drug possession conviction and holds that when the State refuses a defense attorney's diligent pre-indictment request to preserve and produce recordings, which the State or its law enforcement agencies created and are directly relevant to adjudicating an existing charge, the defendant is entitled to an adverse inference charge. In this drug case, despite the attorney's timely preservation request, the State allowed the automatic erasure of a booking room video that likely recorded the search of defendant, which allegedly uncovered the drugs he was charged with possessing. The court also holds the court erred by allowing the State to introduce evidence that defendant gave a false name during the earlier traffic stop.
