Police are searching for Michael Jackson's doctor, hoping that he'll be able to answer questions about the King of Pop's shocking death.
Los Angeles police spokeswoman Karen Rayner has confirmed that police towed a BMW owned by one of the superstar's doctors from Jackson's house.
"We have not been able to interview the doctor yet. His car was impounded because it may contain medications or other evidence that may assist the coroner in determining the cause of death," she told The Associated Press.
Jackson's autopsy is underway, though results aren't likely to be final until toxicology tests could be completed (which could take weeks).
Though some reports claim Jackson may have overdosed on Demerol, Brian Oxman – who has served as the family's attorney for more than 20 years – tells Usmagazine.com he couldn't comment on the types of medications Jackson was taking.
"It is something which is private to Michael, and we'll have to wait for the toxicology reports before we jump to any kind of conclusions," he said. "I only know that I warned that his day may come. And lo and behold, here we are."
Jackson suffered cardiac arrest at his rented L.A. home Thursday and was pronounced dead at 2:26 p.m. PST.
