There was a post on a small website dedicated to family obituaries, and many of his family and friends "lit candles " (aka left posts for the family), and it both was his name and was confirmed by people irl
But this was years ago, I don't remember where the site was nor if it's even still around. Sorry, I don't have your proof you want, you're just gonna have to take my word for it that I verified it myself when it happened. He committed suicide, but I don't know the method. The family didn't post how, just that they were sad he went that way.
