you can not die from crohns disease.

You absolutely can.
I agree the entire thing is suspicious as hell. He signed a will 2 weeks before he died. He signed everything over to his new wife. He even made arrangements for $100,000 to be assigned to care for his two pet dogs. And we are to believe that no one at Quadriga thought it was a bad idea to have the entire cold storage depending on one man's memory? I mean, most people on here will tell you that's a stupid idea. I find it hard to believe no one at a multi-million dollar company thought this was a bad idea.
But, it is completely possible to die from Crohn's disease.
