The frightening 911 call from inside Michael Jackson’s rented estate has just been made public.

Caller: Sir, we have a gentleman here that needs help. And he's not breathing. He's not breathing.
911 Operator: He's not conscious? He's not breathing?
Caller: Yes, he's not breathing, sir.
911 Operator: He's not conscious either?
Caller: He's not conscious, sir.

The mystery surrounding the tragic death of Michael Jackson is deepening amid concerns that he may have overdosed on painkillers.

One report says he was injected with Demerol before suffering cardiac arrest.

Attorney Debra Opri, acting as the family spokesman, wept as she spoke about the loss. “Katherine would say, ‘Leave him alone.’ Joe would say, ‘He's my boy.’ His brothers and sisters would say, ‘What do we do now?’”

An autopsy was performed on the 50-year-old pop icon Friday at the medical examiner’s office but it may be weeks before a toxicology report reveals the full truth about the tragedy.

Some close to Jackson say they saw the tragedy coming.

Filmmaker Bryan Michael Stoller says Jackson appeared sick and frail.

A fan who hugged Michael just three days before his death e-mailed friends saying: "He is a skeleton. He may die."

Jackson family lawyer Bryan Oxman said he has been warning for years that Michael Jackson was risking his life overusing painkillers. “I had warned and I had said, 'If this kind of thing happens to Michael I will not be silent. I will speak up to say that this was a danger that was on the horizon.'”

Jermaine Jackson's heartbreak was obvious as he struggled to announce his brother's death at UCLA Medical Center. His personal physician tried to resuscitate him.

Now police are planning to interview that doctor, identified as Dr. Conrad Robert Murray, as they investigate Jackson’s death. His car has been impounded to be searched. 

Author Diane Dimond says Jackson recently had yet more plastic surgery and was still taking painkillers. “He had prescription drugs in his nightstand in names that were not his own - lots and lots of narcotic drugs. I think it was a habit with him and I think there will be a full investigation.”

A tour bus was passing Jackson’s rented Bel Air mansion just as an ambulance was rushing him to the hospital. A tourist shot video as the bus’s tour guide exclaimed, “How cool is that folks? That's real Hollywood excitement on your tour bus. You just saw Michael Jackson ostensibly, being taken away in an ambulance with the paparazzi racing after.”

Jackson was still being given CPR as he was rushed through the doors of the emergency room.

Minutes later his mother Katharine arrived, disappearing into the doorway. Then his sister Latoya rushed in, agony etched on her face, but both were already too late to say their final farewell.

“This is it and when I say this is it I mean this is it,” said Jackson, announcing his comeback tour in March. He was working hard, perhaps too hard. He had hired famed muscleman Lou Ferrigno to get him into shape and rehearsing late into the night.

His comeback tour won't happen now, but his name, and his music, will be with the world forever.
