LOS ANGELES (AP) - 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 investigation into the singer's death, meanwhile, deepened late Wednesday when the Drug Enforcement Administration was asked to step in by the Los Angeles Police Department, a law enforcement official in Washington told The Associated Press on condition of anonymity because of the sensitivity of the investigation.
