Question: Why was a 20-year old male even allowed inside ("buzzed in") during school hours -- especially a bizarre-acting one? (Unless he was 14 when his six yr old was born, there's no way he could have been a parent.)

I intended to recommend a security system like we had in a classified military building where I worked: a long, bulletproof steel entryway "anteroom", video monitored, with "buzzer"-controlled doors that could be opened only one at a time, that automatically locked, and could not be opened from inside the anteroom. IOW, it was a "man-trap". Once inside, you were stuck until you were personally recognized and "buzzed in" -- or the APs arrived outside to haul you off.

Sounds foolproof -- but... it would have failed at this school.
FAIL! Even though she had had an "altercation" with him the previous day, the dumb@$$ principle "buzzed in" this armed, dressed-in-black sub-adult madman -- AGAIN!! (She died for her mistake.)
NO SECURITY SYSTEM CAN SURVIVE IDIOCY OR CRIMINAL NEGLIGENCE!
Does anybody know who this 4th person in that altercation was and why he wasn’t at school the day the other 3 in that altercation were killed.
