The coroner has finished the preliminary autopsy on Michael Jackson but has little to say other than there was not any external trauma or signs of foul play. Extra toxicology tests have been ordered which will take 4-6 weeks to complete so we won’t know anything until then. There is a ‘security hold’ on the report so not a whole lot of details will be released until the other tests are done.
Presumably this means there was no obvious sign of death such as a ruptured blood vessel or some obvious blockage, and probably it will come down to some sort of accidental death by drugs which led to the cardiac arrest.
