Could it be that other doctors were prescribing medication to Michael? Sources connected with the case tell TMZ ... evidence in the room suggests certain potent drugs were "prescribed and prepared" for MJ to self-medicate.
Dr. Murray's team will not challenge the L.A. County Coroner's finding that Jackson died of a massive Propofol overdose. But , Murray's team will present evidence in the doc's manslaughter case that Michael awakened, then gave himself the fatal dose of Propofol when Murray left the room.  Murray's team hasn't decided if it will use the evidence found in the room to implicate other doctors in Jackson's death.
