The shooter looked pretty normal in his high school pic with his sister and little brother. Short cropped hair, no tats, no hint of anything out of the ordinary.
What was out office ordinary is that his mother was “flighty” and forgetful and his dad busy at the deli and forgetful, both were always late picking the kids up after school in that sports program, so they would always be the last ones left with the coach...
At some point he started living in a small house out back of his Dad-s place, so with the parents being busy all the time and him living in a wholly separate structure and uploading videos to the web, etc., they may not have seen him much at all. Probably no family dinners, etc. Everybody in their own private worlds.
But the physical appearance of the shooter changed dramatically not that long ago. It was in 2019 that the police were getting called to the house. By early 2019 he was already into the internet music scene. When he started to show his mental issues on the outside, was probably 2018 at the latest. About 18 or younger...schizophrenia age. If pot is involved, smoking weed can make schizophrenia symptoms develop 2 or 3 years earlier than they normally would. I hope his younger brother isnt having problems, too.
Interesting profile writeup. IIRC, about 17-23 YO is a common breaking point for the male psyche.
