LOS ANGELES ? (UPDATE 2) There was no evidence of foul play in the death of pop superstar Michael Jackson, Los Angeles coroners said Friday after conducting an autopsy.

Los Angeles County Coroner's spokesman Craig Harvey said a final cause of death on Jackson would be deferred until the results of toxicology tests, due to be completed in "four to six weeks," were known.

But Harvey said that examiners had found no indication of trauma to Jackson's body or evidence of foul play.

"There was no indication of any external trauma or indication of foul play on the body of Mr Jackson," Harvey said.

"The cause of death has been deferred. It means that the medical examiner ordered additional testing such as toxicology and other studies.

"Those tests, we anticipate, will take proximately four to six additional weeks to complete. At that time, once those test results have been completed, we anticipate being able to close the case and issue a final cause of death."
