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, saying only that his office needed to "finish up a bunch of stuff."

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.

In recent days, authorities have searched the Las Vegas home and office of Dr. Conrad Murray, Jackson's doctor. Murray was with Jackson shortly before he died on June 25. Murray's attorney announced today that the search warrant said that Jackson obtained prescription drugs by using 19 different aliases.

Harvey Levin, executive producer of the celebrity Web site, told "Early Show" co-anchor Harry Smith Wednesday that TMZ has records showing Jackson used aliases as far back as 1993. "He used employees of the Neverland Ranch, he used fictitious people," Levin said. "He used the name Josephine Baker, even."

"But this has been going on, not just with Dr. Murray, but literally dozens of other doctors. ... The LAPD and the coroner's office have quietly been going to other doctors. Subpoenas have been served. This is going to open up a massive investigation into what authorities believe could be gross fraudulent prescribing practices. There are a lot of people who are very nervous in Beverly Hills and west L.A. right now."
