Who has a good theory on who the perpetrator is? Charicteristically speaking, no specific person.
Good question. Actually, I think a thread should be made specifically for this very topic.
-I think NOT military trained. But, has the ideation of being an officer (everything about this screams emotional, untrained, rage...then the word 'sloppy' has been used in some reports, as well as leaving a point of entry unassessed with two possible threats still inside; if that were SOP for any branch we'd still be under the English crown or speaking German or Russian, IMO).
-Likely, used the apt parking lot to blend his car in with an environment -if a vehicle was involved. Used the woods in behind second level as a perch; under the cover of trees without being visible to car-traffic.
- I want to compare this case to the Holly Bobo case and the Tate-LeBianca case in so many ways. So, I'll say possibly someone with mindsets of the circles around Zach Adams and Charles Manson. A loser who'd hang out with those groups, maybe.
- Far out loony laughable theory - maybe somebody extremely triggered by the number 11. Happened in November 2022 (11/22), address is 1122, if K was target...K is what number in the alphabet? Heck, maybe he's mad there's only one more season of Stranger Things to roll out? Idk
That's the best I have, thus far.
