The world mourns the loss of a legend.

Developing News: Coronor's office says that the autopsy results are deferred and there are no signs of foul play. More tests need to be taken before they can release results. It has been reported that Jackson has been taking a lot of morphine and oxycontins. Very strong painkillers most times used after surgery or cancer patients. What fame can do to a weak soul.

On the subject of Michael Jackson taking too many prescription drugs...

TMZ went back their files and found a 2007 lawsuit against Jackson for allegedly not paying a pharmacy bill -- grand total: $101,926.66

Mickey Fine Pharmacy in Beverly Hills sued Jackson, claiming he agreed to "pay the purchase price of any prescription medications filled."

The case was dismissed a month after it was filed -- that typically means there was a settlement. It has been reported that law enforcement is looking for a doctor who lived at Michael Jackson's home -- and the doctor is nowhere to be found.

Law enforcement sources say a BMW belonging to the doctor was towed from Jackson's home last night.

Cops are looking to interview the doc.

A law enforcement source said the doctor gave Jackson an injection before he died.

Jackson reportedly may have OD'd on Demerol. As TMZ reported, family members were concerned that Jackson was taking too much morphine.

An autopsy will be performed by the L.A. County coroner today, and while preliminary results are expected by mid-afternoon according to the Associated Press, it may be several weeks before all the results are in.

Many are already starting to blame a cocktail of drugs that Jackson was using for various health reasons.

A source told the London Sun: "Shortly after taking ... Demerol, he started to experience slow, shallow breathing. His breathing gradually got slower and slower until it stopped... His staff started mouth-to-mouth, and an ambulance was called, which got there in eight minutes," the source said.

Jackson's brother Jermaine said that doctors spent more than an hour trying resuscitate the pop singer.

Bryan Oxxen, the Jackson's family's lawyer and spokesperson, put the blame on several prescription drugs thatJackson was taking.

"This is not something that has been unexpected because of the medications Michael was under," he told CNN."This family has been trying for months and months and months to take care of Michael Jackson...The people who had surrounded him have been enabling him. If you think the case with Anna Nicole Smith was an abuse, it's nothing in comparison to what we have seen taking place in Michael Jackson's life."

Life & Style magazine has sources that say Jackson had been using a cocktail of seven different prescription drugs, including Zoloft, Xanax and the Demerol.

The autopsy has been expedited, but it will likely be weeks until the toxicology report can confirm what drugs specifically, if any, contributed to his death.

Rabbi Shmiley Boteach, who counselled Jackson for years and helped him start a charity called Heal the Kids, made this statement: "The saddest aspect to this tragedy is that so many watched it happen and few did anything to stop it. I pray that Michael's death will not be in vain and that we see a return, even among Hollywood celebrities, to the spiritual and family values that are life sustaining."

Jackson had been in rehearsals for 50 upcoming concerts at London's O2 arena and was training with Lou Ferrigno, who had a scheduled training session for today.

Jackson's manager Frank Dileo spoke about his children, telling Britain's Sun newspaper that: "The kids are very upset, but they are fine."

Former South African President Nelson Mandela issued a message through his foundation saying Jackson's loss would be felt worldwide.

Jackson sang at a birthday concert for Mandela in 1998. In 1999, according to local media reports at the time, he lunched with Mandela at a small gathering at which the South African anti-apartheid leader celebrated both his 81st birthday and his and wife Graca Machel's first wedding anniversary.

The Nelson Mandela Children's Fund, UNESCO and the Red Cross were given proceeds from a huge benefit concert in Germany in 1999 that featured Jackson and other international stars.

Former Beatle Paul McCartney, who recorded with Jackson before they had a falling out over ownership of the Beatles catalogue, said his prayers went to Jackson's family and fans.

"It's so sad and shocking," he said. "I feel privileged to have hung out and worked with Michael. He was a massively talented boy-man with a gentle soul. His music will be remembered forever and my memories of our time together will be happy ones."

Questions are also arising about Jackson's estate. The New York Post is reporting that Jackson was $500 million (U.S.) in debt when he died, while various sites are also reporting that he left the rights to the Beatles catalogue to McCartney.
