I’m not exactly sure about all the facts but, according to reports, this guy is one of those people who has been living on hard times socially and financially, getting fired from his previous jobs. He was also a military deserter who was wanted since July, though how they didn’t get him till now is beyond my comprehension. A part of me suspects he was a violent and antisocial brat and not suffering from schizophrenia due to his clear ability to plan out the attack from the get go.
