Jackson's family remains mostly out of sight at their suburban Los Angeles home, where a makeshift shrine to the megastar is growing. Meanwhile, investigators say Dr. Conrad Murray, who was with the singer during his final moments, provided useful information during three hours of questioning Saturday.
Murray was hired to tend to Jackson during his planned summer concerts in London. A lawyer for Murray told the L.A. Times he did not inject the pop star with Demerol before he died.
But many questions still remain: How much medication was Jackson taking? And did a reliance on painkillers contribute to his death?
One time spiritual advisor Deepak Chopra says in 2005 Jackson asked him for a prescription.
"He showed me a little bottle of OxyContin. I started to probe and then got to find out that he was probably seeing several doctors who were giving him narcotics," Chopra said.
Attorney Thomas Mesereau, who represented Jackson during his 2005 molestation trial says even after being acquitted, Jackson was never quite the same.
"He was not constructed, in my opinion, emotionally, for a trial like that," Mesereau said.
However, Mesereau says Jackson was a devoted father who worried about what would happen to his kids if he died prematurely. An ever increasing number of Jackson associates want to care for the children.
Jackson's longtime nanny, Grace Rawarmba, considers herself the children's mother. She is quoted in the Times of London saying that Jackson abused prescription drugs and that she "had to pump his stomach several times."
She is also quoted saying that just hours after Jackson died, his mother Katherine called her and said, "You remember Michael used to hide cash at the house? I am here. Where can it be?"
"If Grace's goal was to recreate herself from nanny to celebrity - bravo, job well done," said Jackson biographer J. Randy Taraborrelli. "But if she had hoped to maintain a relationship with his children, then that was a pretty stupid move."
The Rev. Al Sharpton is expected in Los Angeles to meet with the Jackson family about memorial plans. They could include simultaneous worldwide celebrations.
