Assistant Coroner Visits Michael Jackson Dermatologist Arnold Klein

As part of the ongoing investigation into the death of Michael Jackson, Los Angeles County Assistant Chief Coroner Ed Winter visited the office of the singer's longtime dermatologist, Dr Arnold Klein on Tuesday.
Winter told reporters that Klein had been cooperating with the investigation, and the doctor's lawyer confirmed that his client would provide the requested documents on Wednesday (July 15). While the coroner's office would not reveal what records were being sought, investigators have been focusing on the role prescription drugs may have played in Jackson's June 25 death. Klein has said in recent interviews that he had sedated the singer in the past during medical procedures, but denied giving Jackson unnecessarily large doses of medication.
Winter showed up at Klein's office after the doctor failed to provide records he'd promised to give authorities when they first requested them on July 2, according to TMZ. The site reported that Klein's lawyer sent over partial medical records and promised the rest, but never delivered them. When Winter's office called Klein's to say they had not received the documents, the doctor's reps reportedly never responded.
A definitive cause of death has not yet been determined in the case, as authorities await the results of toxicology tests, which are said to be due within the next week. Among the focuses of the investigation is the role the powerful anesthetic Diprivan may have played in Jackson's death. Numerous outlets have reported that police investigators found the drug at Jackson's home and several sources, including Klein, have said the singer used the drug to combat chronic insomnia.
The Times reported that one of the companies that produces a generic form of the drug was contacted by the federal Drug Enforcement Administration — which has joined the investigation — and asked about a "specific lot number" stamped on the drug's packaging in an attempt to track down the wholesaler or distributor that supplied the Diprivan allegedly found in Jackson's home.
