I don't think this is any concern beyond natural intrigue. The internet comes and goes.

It sucks someone died of course, but if we switched to a house analogy you wouldn't worry about preserving the former owner's claim on the house you just bought would you? Assuming like in this case you have no connection to the deceased.

Maybe I'm a bit too heartless, I dunno, but I feel like you've got no worries here at all. A domain expired, a domain was registered. They share a name solely through coincidence.
