LOS ANGELES, July 8, 2009 (AFP) - After tearful final tributes to Michael Jackson from his children and friends, fans of the King of the Pop faced a new mystery Wednesday over where his final resting place would be.

The death certificate released by the County of Los Angeles Department of Health Services mentions the Forest Lawn Memorial Park cemetery to the Hollywood stars -- where a private ceremony was held ahead of the public tribute Tuesday -- as the temporary location of the body.

But Jackson's family has declined to comment on the location of the singer's final resting place, though local media reported that the coffin was not going back to the Hollywood Hills mortuary. The uncertainty is likely to fuel speculation that the singer may be buried at his beloved Neverland Ranch northwest of Los Angeles.

The death certificate also states the cause of Jackson's demise had been "deferred."

Jackson died on June 25 at the age of 50, and the exact reason for the singer's demise remains unknown, though he suffered an apparent cardiac arrest. Los Angeles coroners have said a final cause of death will not be known until exhaustive toxicology tests from his autopsy are completed in "several weeks."

The document lists Jackson's occupation as "musician," with 45 years in the "entertainment" business. His race is listed as "black" and his marital status as "divorced."

Jackson's daughter Paris grabbed international attention with her heartbreaking eulogy at her father's Los Angeles memorial on Tuesday.

Standing in front of the pop genius's family and a host of rock stars gathered for the farewell event, 11-year-old daughter Paris unexpectedly addressed the audience: "Ever since I was born, Daddy has been the best father you could ever imagine. And I just wanted to say I love him so much."

The youngster dissolved into tears and was consoled by her aunt Janet Jackson before the memorial ended.

Jackson's final journey began at the Forest Lawn cemetery. The ornate golden casket was then taken amid a media helicopter circus to the 20,000 capacity Staples Center, where it was placed at the front of the stage.

The Jackson service began with Motown legend Smokey Robinson reading letters of condolence from those unable to attend, including former South African president Nelson Mandela.

"Michael was a giant and a legend in the music industry. And we mourn with the millions of fans worldwide," Mandela's tribute read.

Tributes were punctuated by performances from Mariah Carey, Stevie Wonder and Jennifer Hudson among others, as Jackson's family looked on approvingly.

Jackson's brothers all wore matching suits, dark glasses and a replica of their sibling's signature sequined glove.

One of the biggest ovations came after rousing remarks by Reverend Al Sharpton, who told Jackson's children to disregard the lurid stories that often swirled around the man disparaged by tabloid critics as "Wacko Jacko."

"I want his three children to know -- there weren't nothing strange about your daddy," said the veteran civil rights activist. "It was strange what your daddy had to deal with but he dealt with it."

Motown diva Diana Ross -- named by Jackson in his will as an alternative guardian to his children -- said she had chosen to mourn privately.

"Michael was a personal love of mine, a treasured part of my world, part of the fabric of my life," Ross said.

Jackson's long-time friend Elizabeth Taylor also stayed away.

The event's producer Ken Ehrlich later said the memorial's pacing was designed to mirror the memorial services of black US churches, mixing uplifting music performances, fiery speeches and poignant pauses.

"People had time to think about what they had heard before we went on to the next order of business," Ehrlich told the Los Angeles Times.

The service drew to a close with a performance of Jackson's 1992 clarion call to end global suffering, "Heal the World," before members of the star's family offered individual tributes.

A live feed of the service was made available free to television networks, while the event was streamed via social networking websites Facebook and MySpace.

Fans gathered to sing Jackson's greatest hits and watch his videos ahead of the event in cities across the globe such as Tokyo, Hong Kong and Berlin.

Jackson sold more than 750 million albums during a four-decade career that was ultimately tainted by repeated allegations of child abuse, his startling physical transformation and his eccentric behavior.

Lawyers meanwhile are busy untangling the labyrinth of legal issues after his death. On Monday, a Los Angeles judge replaced Jackson's mother as temporary administrator of his estate with two of the pop icon's business associates, as instructed by a 2002 will.
