LOS ANGELES, California (CNN) -- A "thorough and comprehensive" report into the death of Michael Jackson is complete, the Los Angeles County coroner's office said, but police have requested that the report not yet be released because of the ongoing investigation.
The coroner's office said it would abide by the request that "the cause and manner of death remain confidential," and referred all questions to the Los Angeles Police Department.
Investigators are trying to determine if anyone should be charged in Jackson's June 25 death. The singer's physician, Dr. Conrad Murray, gave the anesthetic propofol to Jackson in the 24 hours before he died, according to a source with knowledge of the investigation. The source asked not to be named because the individual was not authorized to speak to the news media.
Propofol is commonly known by the brand name Diprivan.
Last week, a source close to the investigation told CNN that the coroner and the Los Angeles district attorney decided that the announcement of the coroner's findings would be delayed indefinitely.
