Dude, a tribute video on the website of the company he works/worked for IS A CITEABLE SOURCE!!!  Don't be a Wikidouche.  Remember, truth doesn't matter on Wikipedia, only citeability.  Based on the lack of local news coverage, I'm inclined to think it's a stunt, but based on Wikipedia guidelines, he's dead.
