I lost a good friend and tech dive buddy last July while on a shallow dive with my wife and I. He jumped 3rd and was supposed to follow Kate. He never showed up at the anchor and must have had either a heart attack or stroke upon jumping in. Drowning is the reason due to medical complications. The family never released the autopsy report info. Bad part about the whole thing is the family (non divers) blamed me even though he was a totally redundant, doubles, bailout, ect, solo diver, good part was he did not suffer more than a minute or two before passing. Compared to something like cancer and the long road to death from it, drowning isn't that bad a way to go imho.
