You may disregard the following, which is based on conjecture:

What school was the shooter transferred to?

Was his mother’s death natural?

Were all 30+ calls to police from his new house about him? (They said his living arrangement changed upon his mother’s death).

Where did he get the gas mask?

How did he hide his weapon and other paraphernalia?

I understand we don’t want to scapegoat groupings of people, but I heard someone being interviewed say “autistic.”

When did his mother die in comparison with when he turned 19?

Did the school assign him a counselor?

He seems to have been in special classes at the school, when he was expelled?

Did he live in a group home?  (poorly subsidized, little staff training).

Was social services involved with him?

Did he have a record as a minor?

I’m just wondering if any of the tragedy (including his) reflects the nationwide cutting back of services to the developmentally disadvantaged (which VOR, a national non-profit volunteer organization. “speaking out for people with intellectual and developmental disabilities– http://www.vor.net  is .)
