Dr. Jan Adams, the plastic surgeon who operated on Kanye West's mother the day before she died, walked out of Larry King's CNN show during an interview Tuesday saying that he had received a request from the West family not appear. "They are on my side and so I'm going to respect their wishes," Adams told King. An initial autopsy was inconclusive and an official cause of death may not be released by the coroner's office for several weeks, news reports indicated. King said afterwards that in 50 years in broadcasting, no one has ever walked out of his show during a live interview.
