LOS ANGELES -- A memorial service for Michael Jackson will take place on Tuesday morning at 10 a.m. at the Staples Center, the 20,000-seat arena located in downtown Los Angeles, Entertainment Tonight reported.
Jackson's final rehearsal took place at the arena the night before he died.
The service will be simulcast at Los Angeles' nearby Nokia Theatre.
Late on Wednesday the investigation into Jackson's death deepened with word that federal authorities will step in to help local police take a look at Jackson's doctors and his medications.
The Drug Enforcement Administration was asked to help the probe 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.
Following Jackson's death, allegations emerged that the 50-year-old King of Pop had been consuming painkillers, sedatives and antidepressants.
The federal agency can provide resources and experience in investigating drug abuse, illicit drug manufacturers known as "pill mills" and substances local police may not be familiar with, the official said.
Also Wednesday, a plan to bury Michael Jackson at his sprawling Neverland ranch collapsed, leaving details about his funeral undecided. 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.
