He credited Murray with saving his life. While on a trip to Las Vegas, Williams said he experienced chest pain. He said Murray performed surgery, putting several stents in his heart.
Williams said he was surprised to see that Murray at the center of an investigation into Jackson's death.
"Hell, he won't give me medicine," he said. "He doesn't believe in giving you a lot of pills. I don't believe he was raised to believe in that."
In August the Los Angeles County Coroner's office ruled Jackson's death a homicide. The office released a statement saying the late King of Pop died because of acute propofol intoxication. The office cited benzodiazepine effect as another condition contributing to his death.
Propofol and lorazepam, an anxiety medication, were cited as the primary drugs responsible for Jackson's death. The statement said other drugs detected in his system were midazolam, diazepam, lidocaine and ephedrine.
The coroner's announcement came after a newly unsealed search warrants revealed that police found marijuana and numerous empty drug bottles at Jackson's home shortly after he died.
During the search police said they found two bags of marijuana; a bottle of the drug temazepam, which is used to treat sleeplessness; and empty bottles of the sedatives lorzaepam and diazepam. Police also found four other empty pill bottles, though they could not say what they may have contained.
The warrants, which were served on June 29, also say that the day Jackson died, while investigators were at the house, "family members of the decedent notified Los Angeles County Coroner's Assistant Chief Ed Winter that they had located a quantity of tar heroin in [Jackson's] bedroom on the second floor of the residence. Winter notified LAPD detectives of the found evidence." The warrant does not say if the evidence really turned out to be heroin.
Among the items seized from Murray's Houston office back in July were a vial containing 27 tablets of the weight loss drug phentermine, a vial containing a tablet of the muscle relaxant clonazepam, a photocopy picture of Murray, Rolodex cards, public storage receipts, and a receipt for a "Cricket" cell phone, according to a receipt attached to the warrant.
Cricket phones essentially are untraceable, because the company requires no contracts, no credit checks and no set-up fees, according to a sales representative for the company. Cricket also offers a "PAYGo" option, which means someone can go to a store and pay for phone minutes with cash.
Other items seized from the storage unit, according to the court records, included two computer hard drives and a "Texas Department of Public Safety controlled substance registration." Authorities also obtained a suspension notice from a Houston hospital.
An administrative assistant at Doctors Hospital in Houston confirmed to the Los Angeles Times that Murray had been suspended from practicing at the hospital. The offense was "very much" routine and minor, she told the newspaper.
