Details are starting to trickle out about this guy, and how meticulously he prepared and pulled this off. It doesn't point to any mental illness, other than perhaps extreme narcissism. But there's still no word on motive. No manifesto. No social media postings. Not even a note. Bizarre. What if the guy just woke up one day, looked at his booze soaked, gambling addicted, depressing life and thought "eff it, I bet I could do this"?
