The Secret Michael Jackson Witness

Two months after Michael Jackson passed away, the stories surrounding his death continue to break. Now, ET special correspondent Diane Dimond is with Dr. Susan Etok, the doctor that Michael reportedly begged to be his pipeline to drugs during his London tour. Does she believe he was murdered? What did she tell police? "I basically told the police what I knew, who I thought was involved and what I thought happened to Michael," says Etok, who made it clear that she refused the late King of Pop’s request for such prescription drugs as Demerol. "[Etok] was part of Jackson's inner circle for more than a decade, a confidant the singer ultimately tried to use as a drug connection," says Dimond. "Now, she's assisting in the criminal investigation focused on Michael's broad net of drug suppliers."
