I’m grateful that LE let us know there was no evidence of SA. That helps to know, unlike in some cases like Abby’s and Libby’s where they don’t say anything and we can’t rule that motive out for five plus years.
Of course that’s another question in itself, how reliable is that testing, what constitutes SA, etc. But taking that at face value, what LE says, that there’s no SA...
This is what leads to possible motive simply possibly being “desire to kill.”
My first guess on motive was SA. So with that being put aside...
I’m thinking incel type, rejected, younger, possibly video games and *advertiser censored* all day JMO
