Multiple law enforcement sources tell us the toxicology report in the Michael Jackson case shows Jackson had a lethal amount of the anesthetic Propofol in his system — but that wasn’t the only drug.

We’re told the toxicology findings show there was also alprazolam — also known as Xanax — in Jackson’s system. Xanax is used to treat anxiety.

But our sources say Propofol was — as one source put it — “front and center in terms of why [Jackson] died.”
