Casey Johnson Autopsy Done, Results Deferred

Los Angeles coroner says no signs of trauma, but it could take up to eight weeks for toxicology test results to come back

As we figured, the final word on Casey Johnson's death won't be for a while.

The Los Angeles County coroner has completed the autopsy on the Johnson & Johnson heiress but has deferred drawing any conclusions on what killed the 30-year-old socialite, who was found dead yesterday at her Hollywood home.

In a statement, the coroner's office said there was "no evidence of trauma to the body," which backs up the LAPD's announcement last night saying Johnson, who was a diabetic, appeared to die of natural causes.

It could be up to eight weeks before we learn the results of toxicology tests and microscopic studies of the body.
