Police trying to establish what killed Michael Jackson are seeing the King of Pop's death as a possible murder, say reports.
According to TMZ, "multiple law enforcement sources" have revealed that Los Angeles Police Department have initiated a full-blown murder inquiry.
The probe centres on Dr Conrad Murray, the physician with Jackson when he suffered a fatal cardiac arrest three weeks ago, reports the Independent.
He's under scrutiny for prescribing powerful sedatives to the 'Thriller' hitmaker.
Although the LAPD spokesperson denied the report, however it didn't rule out homicide as the cause of death.
Suspicions have been raised by the Murray's public statements where he denied reports that he had injected him with Demerol or Oxycontin but refused to tell reporters whether he injected him with another potentially deadly drug, Propofol.
