Los Angeles, July 18 (DPA) The coroner's report into the death of Michael Jackson has been delayed for another two weeks as speculation continues to swirl about the cause of the megastar's June 25 death, the Los Angeles County coroner's office said Friday.

Prior to the announcement, the coroner had been expected to issue the report at the beginning of next week. Initial comments by officials indicated that Jackson had died from cardiac arrest, possibly caused by an addiction to prescription painkillers.

But over the past two weeks there has been mounting evidence that Jackson used a dangerous hospital anesthetic to overcome his insomnia as he prepared for his 50 concert comeback in London.
