I actually know a vaguely similar story involving a very well-liked guy from a mailing list I used to be on.
He got a cancer diagnosis requiring him to go on heavy-duty chemotherapy and was keeping a very positive attitude ("I'm going to beat this with my doctors' help!") His first or second chemotherapy session, the drugs triggered a sudden heart attack and he died.
He had been running an OpenSRS-based domain registry, and nobody else knew the PWs.
