Sad to hear things like this happen and people still think mental illness is a joke.
I wasn't joking, but I think there was a connection in this case.

But I really don't get the crossbow part. I know mental problems can impair normal thinking, but what exactly would he have done with it?
It seems to be difficult to shoot yourself with this weapon, but I'm not sure, I don't know much about weapons, so I think it was to threaten anyone who came near him, I think he just used this one because there was no other one, if he had a gun, he would probably use it.
