It has been reported that the Los Angeles County coroner has ruled Jackson's death a homicide. Captain John Kades, of the coroner's department, said he was not in a position to confirm or deny the report. He added: "We have not released any information on the Jackson case. We do not know where this information is coming from."

A search warrant made public in Houston disclosed that a high dosage of the anaesthetic propofol was in the late singer's system when he died at his rented Los Angeles property on June 25.

Police investigating Jackson's death have reportedly been working on the theory that the singer's personal doctor, Conrad Murray, administered the medication to help Jackson sleep hours before he collapsed.
