This is in Noblesville, Indiana. Not sure it it is rural, urban or suburban. But likely the shooter is a juvenile, so the media is oh so careful in hiding its identity. The did use the pronoun he, so likely a male or at least a male wanna be.
Male peep, female victim.... If this turns out to be another spurned adolescent, let’s hope the floodgates of copycats aren’t opened. Nor that the media will help in that regard.
I live 7 miles by road or about 5 miles from that school as the crow flies. I would estimate 80% Upscale Suburban with a 5% Rural kids and 15% Towneys. There is a Section 8 apartment complex that sends kids there, but even that is pretty descent. It is Pollyanna Midwest in a place with virtually no unemployment and really low crime.
