At the time of his death, Jackson was in rehearsals for a 50-show comeback concert series to be kicked off at The O2 arena in London. Many said the show would remind people why Jackson was a huge star and salvage his legacy from the mire of child-molestation allegations, his infamous plastic surgeries and bizarre public behavior.

Instead, Jackson was pronounced dead at 2:26 p.m. on June 25, 2009, at the UCLA Medical Center in Los Angeles, where hed arrived with no heartbeat and efforts to revive him failed. The autopsy found that the singer died from a lethal dose of propofol, a powerful anesthetic used to put patients to sleep for surgeries in hospitals.

As it turned out, Dangerous was not just the title of one of his many multi-platinum albums, it was also an accurate way to describe the drug use that dominated his life.
Murray admits to administering propofol to Jackson that morning after working all night to help the singer sleep with the use of other sleep aids. The doctor said he was trying to wean Jackson off an addiction to propofol, which he said the star referred to as his milk. But Murray says he gave in to Jacksons repeated requests for the anesthetic at 10:40 a.m. He told investigators he left the room only oncefor just two minutesto use the bathroom and returned at about 11 a.m. to find Jackson unresponsive and not breathing.

Dr. Conrad Murray and his attorney
(Reuters/Landov)Murrays cell-phone records reveal that starting at 11:18 a.m. he made three separate phone calls lasting a total of 47 minutes and that a full 82 minutes elapsed before 911 was called. A police affidavit in the case stated that this delay indicated Murray was not monitoring his patient or was making frantic calls after discovering Jackson not breathing.

The affidavit also stated that Murray never told the paramedics or emergency workers about the propofol and refused to sign Jacksons death certificate.

Murray has pleaded not guilty and is free on $75,000 bail. He has maintained that he administered safe doses of propofol and lorazepam, an anti-anxiety drug said to be a contributing factor in Jacksons death.  Murray faces up to four years in prison if convicted.

Murrays attorney, Ed Chernoff, told CNN the amount of propofol found in Jacksons autopsy was much higher than the dose given by the doctor, and hinted that someone else or Jackson himself administered the fatal dose.
