Jackson Autopsy Results...Don't Hold Your Breath

Coroner says cause of death won't likely be announced for several more days as probe continues

The world can't wait for the whole Michael Jackson death mystery to be resolved.

But apparently the coroner didn't get the memo.

Just a day after telling E! News that his office was "still shooting for the end of the week" to announce an official cause of death, Los Angeles County Assistant Chief Coroner Ed Winter now says the results won't likely be out until next week.

While Winter did not specifically state a reason for delay, it appears his office is still trying to gather evidence. Earlier today, a subpoena-packing Winter turned up at the Beverly Hills offices of Dr. Lawrence Koplin. Jackson dermatologist Dr. Arnold Klein reportedly once performed a procedure on the singer in Koplin's office.

Asked if he had ever seen a case like this before, Winter simply said, "No, I have not."

Authorities are trying to build a manslaughter case against Jackson's personal physician, Dr. Conrad Murray, and would like corroboration from the coroner.

While Murray's lawyer has insisted otherwise, investigators with the LAPD and the DEA believe the doctor gave Jackson a lethal dose of the sedative propofol. Detectives have carried out raids on Murray's Las Vegas home and office and his Houston offices and storage facilities.

Capt. John Kades, an investigator with the coroner's office, tells E! News that "every day we get a little closer to the cause of death...[but] nothing has been finalized.

"The bottom line is [Jackson] died back on June 25, and at that time we were estimating four to six weeks before we could determine the cause of death. So we're still within that window," he said.
