Death due to Crohns related whatever at that age is extremely rare, especially when they mention he was otherwise young and healthy (if I misread or am misremembering about the otherwise healthy part, correct me)
& somebody with that sort of money, that also spends $90k at a La Z Boy to furnish a house, would be 9001% on top of any possible thing that Crohns could do to him.
Guarantee he’s alive & he otherwise would’ve gotten away with it if they went with a story of any other medical condition that can lead to sudden death.
(I realize this may sound insensitive to those with or knowing somebody with Crohns. I have Crohns :P)
