Multiple sources tell TMZ Michael Jackson had dozens of injection sites all over his body.
As we first reported, Propofol, a powerful anesthetic, was found in the house after Jackson died. Various medical experts tell us there is absolutely no medical justification for Jackson to have had this drug in his home -- it is used to knock people out before surgery. It is administered through an IV.
We're told Jackson wanted the drug to sleep and that he had cravings for anesthesia -- whenever he had even the most minor medical procedure ... he had the doctor put him under.
It is increasingly looking like Propofol may have caused Jackson to go into cardiac arrest and die. The doctors we spoke with say it's reckless for any doctor to supply Jackson with Propofol and especially reckless to administer it to him at home.
The fact that Jackson had dozens of injection sites on his body would have made it clear to any doctor that Jackson had a drug problem.
Criminal manslaughter is defined as the reckless disregard for human life. The talk in law enforcement -- this case seems to fit the bill.
