Senseless

I have a pretty depressing new case I've been working on for a few weeks. An ex Marine, living in his parent's converted garage for a few years, walks into a store and puts his gun to the temple of a woman sitting on a nearby bench. He kills her instantly. He then shoots two employees (one of whom will be in a wheelchair for the rest of his life) before turning the gun on himself.

I now have to sort out this situation, communicate with the police, and basically wade through the mess this guy left behind. Ugly, ugly, ugly. No motive that anyone can find (and many folks have been looking very hard), no evidence that he'd ever been in the store previously or knew of any of the people involved. He was a bit of a nut, and had some prior incidents with the police, but nothing that would clue you in to what was going on in his dome.

Keep your head on a swivel, folks.
