Tragically a basic profile of him has been posted. Honour student apparently always in some form of flight mode or in it in unreasonable ways. Hard to say what drove him this far.

I doubt he displayed behaviours of being potentially this dangerous. He apparently killed his mother at home before going to the school. I wonder over the years what his parents had attempted to get him out of his obvious isolation? Perhaps they were just too busy and ignored the situation. We always kept an eye on our children to make sure they were well within the normal envolope. Took the time to adjust things if they were not. Never just sitting on or ignoring situations. It was not the type of personality profile I expected to emerge for this act.
