'Potentially Lethal' Traces Of Propofol - revealed by Michael Jackson's autopsy

The second autopsy carried out on Michael Jackson's body found needle marks and traces of a potentially lethal amount of Propofol in the singer's system, according to unconfirmed reports.The results of the autopsy requested by the Jackson family two days after the star's death on June 25 are “consistent” with those of the examination carried out by the Los Angeles County Coroner's Office a day earlier, a source tells E!Online.com.
The results are not expected to be made public for another week due to the on-going investigation into Jackson's death, however, it has been widely speculated he died after being given Propofol, a powerful sedative that should only be used in hospitals.
Investigators are said to have been interested in the singer's live-in physician Dr Conrad Murray - who was at Jackson's Los Angeles home when he went into cardiac arrest - and other doctors who prescribed and administered drugs to Jackson over the years
