Search warrants served at the Las Vegas home and office of Dr. Conrad Murray show investigators think Michael Jackson was a drug "addict", RadarOnline.com has learned.
The warrants, signed by Las Vegas judge District Judge Timothy Williams, say "there is probable cause to believe" that searches would uncover evidence at the Las Vegas home and office of Dr. Conrad Murray of excessive prescribing, prescribing to an addict, excess treatment or prescribing, unprofessional conduct, prescribing to, or treating an addict and manslaughter.
They cite "probable cause to believe" that the premises contained "records, shipping orders, distribution lists, use records relating to the purchase, transfer ordering, delivery and storage of propofol (Diprivan)."
Officials are working under the theory that Propofol (trade name Diprivan) caused Jackson's heart to stop.
It's not known when Jackson's autopsy results will be released.
