I smile when I read this in the articles.
An autopsy does not usually happen in Thailland. They are expensive.
When my wife died in her sleep, there were a few issues about releasing her body. Usually to do with money being required.
We were eventually told that there would need to be an autopsy and that the body would be released after that. Money please.
In the end, I had to call on some 'influential' people to get her body released. (Family had flown from the UK and they needed to go back.)
There was no autopsy. No report. But there was an extra charge for the additional week's 'storage' in the morgue at the government hospital.
In this case, as it is a high profile one, I am sure that there will be some sort of an autopsy - but will the published results and cause of death be the real ones?
