LOS ANGELES - Michael Jackson's family wants an independent autopsy to determine the cause of the King of Pop's death, Rev. Jesse Jackson said Saturday.

The family told Jesse Jackson about its wishes while he spent time with them during the past two days, the reverend said in an interview with The Associated Press.

He said there were unanswered questions surrounding the death, including the role of the personal cardiologist who was with Michael Jackson when he died.

The Los Angeles County coroner's office performed an autopsy on the singer's body Friday but deferred a finding on the cause of death pending further tests that could take more than a month.

Coroner's officials said they released Michael Jackson's body to his family late Friday night. Jesse Jackson did not say if an independent autopsy had been arranged.

Spiritual teacher and medical doctor Deepak Chopra said earlier Saturday he had been concerned since 2005 that Michael Jackson was abusing prescription painkillers and most recently spoke to the pop star about suspected drug use six months ago.

Chopra said Jackson, a longtime friend, asked him for painkillers in 2005 when the pop star was staying with him following his trial on sex abuse allegations.

Chopra said he refused but added the nanny of Jackson's children repeatedly contacted him with concerns about Jackson's drug use over the next four years.

Janet Jackson arrived at her brother's Holmby Hills estate Saturday, where moving vans pulled up earlier in the day and about eight movers took dollies and packing equipment through the gates.

The vans left after being inside the estate for almost an hour, and it wasn't immediately known what had been taken out.

Most of Jackson's family members were at the Encino compound, where they were contemplating funeral arrangements and caring for his three children.

They are feeling confused, upset and angry by the lack of information about those who were around the pop superstar in his final days, a person close to the family said.

Jackson's family also wants to know more specifics about what role AEG, the concert promoter that was staging his 50-date concert series at London's 02 Arena, was playing in his life, said the person, who requested anonymity because of the delicate nature of the situation.

They also want to know more about the role of his advisers and representatives, who they believe were put in place by the promoter.

AEG spokeswoman Natalie Whorms in London had no comment.

Jackson never communicated to his family who he had in place to handle his business affairs, the person said, adding that they were told by the singer's phalanx of advisers that he likely had a will, but it may be many years old. The family is distrustful of what they are being told -- but are determined to find out more, the person said.

"There are decisions going down without the family being in the loop; it's becoming an issue," the person said.

Randy Phillips, AEG Live president and chief executive, said Friday it was Jackson who insisted that Dr. Conrad Murray, a financially troubled cardiologist who was with the entertainer when he collapsed Thursday, be put on the tour payroll.

"As a company, we would have preferred not having a physician on staff full-time because it would have been cheaper without the hotels and travel, but Michael was insistent that he be hired," Phillips said. "Michael said he had a rapport with him."

Houston lawyer William Stradley said his firm had been hired by Murray.

Jackson collapsed Thursday at his rented home in Los Angeles. Police seized Murray's car in search of evidence but have insisted that the doctor has been co-operative and do not consider him a criminal suspect.

Records reveal years of financial troubles for Murray, who practises medicine in California, Nevada and Texas; his Nevada medical practice, Global Cardiovascular Associates, was slapped with more than $400,000 in court judgments, and he faces at least two other pending cases and several tax liens.

The person close to the family said that while there were reports that the singer was distant from his family, Jackson spoke with his mother, Katherine, quite regularly and his father, Joe, had seen his son shortly before his death.

His other eight siblings, including Janet, may not have talked to him recently but were not estranged.

The pop star left behind three children: Michael Joseph Jackson, known as Prince Michael, 12; Paris Michael Katherine Jackson, 11; and Prince Michael II, 7. The elder children were born to ex-wife Deborah Rowe, while the youngest is his biological son, born to a surrogate mother.

Rowe and Jackson married in 1996 and divorced in 1999.

The family is still trying to determine what kind of memorial to have for Jackson and when, and are debating between the idea of having a private ceremony or a grand celebration open to the public, the person close to the family said.
