What are people going to say, "Yeah, I knew he was gonna do it, but I had other shit going on so I ignored it." Meaningless quote you hear all too often after people commit suicide unfortunately. And I don't mean to admonish anyone, but who comes out afterwards and says "Yeah, his life was shit and he was a miserable fuck it was only a matter of time."
Are you seriously not seeing why professional contacts would be more likely to have a fair opinion and share it? It’s his lawyers that said he didn’t seem suicidal.
Or are you seriously just trying to insist it’s not suspicious any way you can?
