For the curious, I looked it up. The reason he had access to a 6th grader to shoot in a High School is that it and the Middle School are really one big building in this case - so while it was a High School, it was also a Middle School.
This article lists a possible motive - years of bullying with the school admin refusing to do anything about it. I never did understand why none of my public schools ever did anything about my bullies. As an adult, if any of them tried it I’d call the police and use pepper spray - both banned actions in my schools.
Calling the police is a banned action??
Schools typically wait until there’s already a School Shooter before letting more in!
