I didn't know about this thing. I thought he was buried completely. That's quite horrible why did they do that? Are they going to preserve it?
Cutting the brain from the head is a usual medical procedure after someone dies, and an authopsy needs to be performed.
Unfortunately, your sickness would be prolonged even more as there would be more speculation as regards the cause of his death for two more weeks, until the result from his brain is made public. Regards, RightMAn
