Certain items found in the room where Michael Jackson died could help shape Dr. Conrad Murray's defense -- namely, that other docs were medicating 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.

As we first reported, Dr. Murray's team will not challenge the L.A. County Coroner's finding that Jackson died of a massive Propofol overdose. But as we told you, 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.

We're told Murray's team hasn't decided if it will use the evidence found in the room to implicate other doctors in Jackson's death. But we do know Murray's legal team will present evidence during the trial that the fruits of Jackson's notorious doctor shopping over two decades wore his body down.

The rep for Dr. Murray's lawyer refused comment.
