Police declined to answer questions about how they identified Crimo.

Another one who was on their radar and just happened to slip through.

Same questions as many other shooter incidents. Similar responses from officials.

So, why did the background checks not flag him?
When and where did he get the gun(s)? ammo?
When and under what circumstances did he first become known to 'officials'?

Another troubled youth who failed to get the help he needed.
