He had a good legal team. Interesting that his previous was not presented to the jury. I think it would have been used in sentencing if he was found guilty. I don't think he set out to kill anyone - he was just unlucky that the deceased was not a normal healthy specimen, however he should face a lesser charge of assault as it was clearly gratutious violence. He can still be done for some kind of homicide through the Civil law as on the balance of probabilities it looks he was responsible for the deceased demise.
