Unless he was killed by a bear and that bear is still on the loose, or something like that, then I think we can probably wait a few days for his family to be informed.
There are a lot of people here making very high-minded comments about how it’s deeply important to the sum total of human knowledge that we learn the cause of his death so that we can reflect on our mortality, and so on and so forth. I can’t help but feel those comments are a bit insincere. It’s morbid curiosity, let’s be honest, and it’s not enough to justify speculating when his family and friends are probably reading these comments and possibly haven’t found out.
