The Los Angeles County coroner's office says release of Michael Jackson's autopsy results will be delayed.
Coroner's officials had said they were going to release the results this week but Assistant Chief Coroner Ed Winter said Wednesday the announcement will probably not come until next week.
Winter did not discuss reasons for the delay.
Jackson died June 25.
A law enforcement official has said investigators are working under the theory that the powerful anesthetic propofol caused Jackson's heart to stop. The official spoke on condition of anonymity because the investigation is ongoing.
