I am sure they did a criminal check, this shelter is AMAZING - I doubt they would hire someone they felt they couldn't trust. The blame shouldn't be on them, I mean he went psycho, from what I've read. There's not explaination as to why he did it. This guy never appeared to be like that..like I would've never thought this would happen.

It's scary that I have seen him around before, it's weird to think I've walked by this guy before and never knew..
