Second autopsy conducted at Jackson family's request

The Jackson family sought the independent autopsy amid confused anger and frustration over the final hours of the tragic pop icon's life. The initial autopsy, conducted by the Los Angeles Coroner's Office, said there was no evidence of foul play or external physical injury to Jackson, officials said.

The Coroner's office said Friday a preliminary autopsy on Jackson was inconclusive and a final cause of death would not be known until exhaustive toxicology tests are completed in "six to eight weeks."

Jackson's family members were huddled at their family compound in the northern Los Angeles suburb of Encino, where they have been based since the most famous member of their clan died suddenly on Thursday at age 50.

Jackson's body was released to his family under cover of darkness late Friday, and was being kept at an undisclosed location, officials said.

The second, privately conducted autopsy was requested by the Jackson family as they become increasingly frustrated by unanswered questions surrounding Jackson's death, focusing their attention and ire on the role of the singer's doctor, identified as Conrad Murray.

Murray is reported to have injected Jackson with the powerful painkiller Demerol shortly before his death.

Meanwhile removal vans could be seen entering the driveway of the mansion in Los Angeles where Jackson collapsed, CNN reported Saturday.
