Investigation into Jackson's death continues

LOS ANGELES, July 10 (Xinhua) -- The investigation into Michael Jackson's death continued on Friday, with the focus on painkillers the King of Pop may have used, and the doctors who gave them to him, the Los Angeles Times said on its website.

The coroner's office subpoenaed "any and all" of Jackson's medical records, "including radiology and psychiatric records," a source familiar with the investigation told the paper.

One of the subpoenas was served on Dr. Arnold Klein, Jackson's dermatologist, the paper quoted the doctor's attorney as saying.

"It was a standard form subpoena and we turned over medical records to the medical examiner in response," attorney Richard Charnley said.

Klein appeared on ABC's "Good Morning America" earlier this week and denied that he ever gave Jackson dangerous sedatives such as Diprivan, which was reportedly found in Jackson's Holmby Hills home after he died on June 25.

Meanwhile, a probate hearing earlier this week put an attorney and a record producer named in Jackson's will temporarily in charge of his estate, which has been estimated to be worth a half-billion dollars.

The judge also gave Jackson's mother Katherine temporary custody of his three children, pending a custody hearing on Monday.

A nurse has said Jackson once asked her for the drug to help him sleep, which horrified her.

The cause of Jackson's death has been listed as deferred, pending the results of toxicology tests, which typically take around six weeks, and neuropathy tests, which require the brain to have hardened -- a process that takes about two weeks. Part of Jackson's brain remains with the Los Angeles Police Department.

Although two private services were held at Forest Lawn Hollywood Hills for Jackson, it is still unclear where the entertainer's final resting place will be.
