Preliminary toxicology reports on Michael Jackson's body show the singer took a cocktail of drugs strong enough to kill a normal person instantly.
And Jackson’s sister La Toya has claimed he was killed by a bunch of greedy hangers-on who got him hooked on drugs.
The 53-year-old has told British Sunday newspapers that she believes Michael was murdered.
“He was surrounded by a bad circle. Michael was a very meek, quiet, loving person. People took advantage of that,” she told reporters.
Lethal levels of the powerful painkiller Demerol and heroin substitute methadone were found in Jackson's blood, UK's The Sun newspaper reports.
Jackson took large quantities of the drugs for so long that his body became tolerant to huge doses until he collapsed of a cardiac arrest
“Michael Jackson was a walking drug store when he died, he never stood a chance,” the newspaper quoted a source close to the case as saying.
In addition to the Demorol and methadone, Jackson was found to have therapeutic levels of Fentanyl a drug 100 times more potent than morphine Valium, a sleeping drug called Ambien and the painkiller Vicodin in his system.
He was also taking high doses of the anti-depressant drug Zanax, the hospital anaesthetic Propofol and post-surgery painkiller Dilaudid.
