Thanks for sharing that, Furyman. I'm sorry for the loss of your friend.
I have a coworker who I constantly see under a car held up with a jack, and no stand present.
Sometimes he will use a stand, but too often not. I've placed stands underneath before, while he was working. I've made comments. Now, I just shake my head. I think he believes he's faster than a falling car.
I fully expect that one day someone wil enter the other building and find him like your friend was found.
