I'm just trying to square the idea of him being a regular guy with someone who goes Rambo on balconies and shoots at cops and other civilians after a murder of passion. How many regular guys you know be doing this?
RIP to the poor lady.
He worked at UPS and was a safe bet, I'm sure the signs were there early on it was too late.
Her being a lawyer (dealing with psychos) should have gave her extra insight into sensing the intentions in people...
