Sadly, he's bipolar and when those with that affliction get off their meds, crapola happens. So many of these shooters, or machete hackers recently and over the past few years that have been identified as "mentally ill" usually have term bipolar dropped somewhere by a family member in the follow-up interviews. TCU & Raider's Barret Robbins was bipolar and his disappearance the evening before the '03 Super Bowl was directly tied to his going off his meds as were the troubles he repeated got into over the next 13 years before bing sent to a mental institution in '16 for slugging a mother & her daughter. Guidance and support from friends & whomever are all fine and dandy, but once that last intake of medication wears off in today's high tech, in your face 24/7 intensity, all bets are off. In his case, as in so many others, independence and thrills kill. If he doesn't stay on his meds, he will most likely be imprisoned, institutionalized or interred.
