Wonder if they were wearing seatbelts. However, with this kind of crash, it has a potential to be fatal even if they were. The truck probably smashed right into where he was sitting. An S10 vs. a small Hyundai sedan (I can't recall of the top of my head where that model sits in their size lineup) is pretty damn serious.
You don't really wish anyone ill will, nor do you wish to appear indifferent to someone's death, but lately it seems the Internet needs a lesson in appropriate expressions of emotion regarding the passing of people you don't actually know, even as acquaintances. The Internet seems to warp social norms in that way, I guess. You feel like because you read about them or whatever, you "knew" them. No, you didn't.
That they had the same fetish inclinations as you is not really a reason to see it as any different than anyone else in the obituaries on a given day.
For what it's worth,
Chris Sturtivant- an engineer with VMware who was known in furry for organizing a muck, as well as some kind of involvment with FC- died, and nowhere is anyone saying how or why, other than it was "unexpected". Appears to have been in his 30s somewhere, was
"openly polyamorous", whatever that means. Probably not too weird for certain crowds in California.
Probably they don't know, could very well have been some kind of undetected heart condition, aneurysm, or something of that nature.
