LOS ANGELES –

A plan to bury Michael Jackson at his sprawling Neverland ranch fizzled Wednesday, leaving details about his funeral undecided as another mystery was solved: His newly unveiled will says his mother should raise his children, or failing her, Diana Ross.The changing funeral circumstances thwarted many Jackson fans who had descended on the estate in the rolling hills near Santa Barbara with the hope of attending a public viewing."We're terribly disappointed," said Ida Barron, 44, who arrived with her husband Paul Barron, 56, intending to spend several days in a tent.

"We were going to listen to music and watch Michael Jackson DVDs and party all night long, not just to have fun, but in memory of Michael Jackson," Paul Barron said. "Now we're going to have to just go home." Jackson's 7-year-old will, filed Wednesday in a Los Angeles court, gives his entire estate to a family trust and names his 79-year-old mother Katherine and his children as beneficiaries. The will also estimates the current value of his estate at more than $500 million.

Katherine Jackson was appointed their guardian, with entertainer Diana Ross, a longtime friend of Michael Jackson, named successor guardian if something happens to his mother. Ross introduced the Jackson 5 on the Ed Sullivan Show in the late 1960s and was instrumental in launching their career.

Meanwhile, Jackson family spokesman Ken Sunshine said a public memorial was in the works for Jackson but wouldn't be held at Neverland. In addition, it appeared more likely that a funeral and burial would take place in Los Angeles, a person familiar with the situation told The Associated Press.
