Definitly
I think definitly he was musederd.. He was not a man to rushed to hospital from ambulance and neigher call 911. He was one of the richest in states.. So he must had his own physicians and medical centres.. And some reporters said it was pain killers and earlier it said he was died from cardiac arrest.. These all facts leads to murder suspect.. on my knowledge he had more than 2000 aces in his house premises including cinema and mini zoo, and if he had heart problem definitly he will build his own hospital.. And by the way he was simple and peacefull man.. Must be in heaven now..
