Welcome :D Thanks for writing it. Seems like a lot of research hehe. I was trying to think of a topic, but only started to think on the Friday before it was due on Monday, so that was like 2 days. Maybe next DD i'll submit something ;)
I also thought that the psychological state, if real, would indicate a 'reason' for a suicide. But, knowing how people end up dead when they are accused of as a scapegoat, or people who are silenced form speaking because they are dead... I tend to go with the latter than a real suicide. Like you say, the psyche profile was justification to insinuate his guilt and make him an easy target, especially for silencing by 'suicide'.
