Except you have no evidence of any of that.
The facts are simply those set forth in the article and one other on FR. I have no idea whether they are true or not.
Guy told cops “I figured I would die in the attack.” Article says he came out here in part chasing girl he’d met over there who lives here. They say he was suicidal. They say his money ran out They say he was depressed (sounds like romance didn’t take off, right?) They say he was unskilled because he dropped out of friggin’ high school—sounds reasonable. They said he had no money, ergo one can reasonhe had no job. So, those are the facts as reported, make what you will of them.
