Los Angeles court officials say a lawyer has filed Michael Jackson's will.

The document, from 2002, asks for the pop star's entire estate to be put in a family trust and names his 79-year-old mother as a beneficiary of the trust and the guardian of his three children.  Singer Diana Ross is named as a successor guardian.

Crowds of fans and reporters have gathered outside the gates of Jackson's Neverland Ranch, over speculation a memorial service may be held at the sprawling estate that once had a zoo and an amusement park.

Sales of Jackson's music have soared since his sudden death last week at the age of 50.  The cause of death has not been determined yet and funeral arrangements have not been announced. 

The coroner's office in Los Angeles said there were no indications of external trauma or foul play.  But the office said it will take weeks for test results to come back.  Jackson's family ordered a private, second autopsy.

Jackson died as he was preparing to launch a series of 50 sold-out comeback concerts next month.

In New York, the Apollo Theater held a public memorial for Jackson on Tuesday.  The singer won the theater's amateur contest in 1967, performing with his brothers as The Jackson 5.
