The coroner’s office decided to delay the release of the autopsy report after officials from the Los Angeles County District Attorney’s Office, the Los Angeles Police Department and the coroner’s office had a meeting to discuss the case, according to Ed Winter, assistant chief of the coroner’s office.

Winter said he could not say when the cause of death of the late King of Pop would be announced.

Court records indicated that police investigators were looking for evidence of communications between Murray and other health practitioners.

Investigators searched Murray’s home and office in Las Vegas earlier this week, seizing e-mails, letters and notes between the cardiologist, Jackson and other doctors who treated the singer.

The results of toxicology tests from the official autopsy on Jackson’s body were widely expected to show that Jackson was taking propofol, a strong sedative usually used in a hospital setting for general anaesthesia.
