I can't rationalize how any of the symptoms he described, and having undergone many medical tests which were not described as indicating any end-organ dysfunction, would result in to organ failure which I've never heard of happening "out of the blue".
I fully respect his family's right to privacy and of course don't expect a full disclosure. The physician in me is very interested in learning more about what happened in either his or another case. From a medical perspective this is a very shocking turn of events that has not yet been described to my knowledge.
The only place I can find claims for organ failure are on conspiracy forums. I can't put much credence in the idea, yet.
I kinda regret not taking a deeper look at that website first but at least the news is out and people are talking about it and remembering him.
I wish there was a way to archive all his posts but of course now that's even more impossible given twitter's degradation
