I think the manager will do the right thing and maybe half the reward with the co-worker or divide the money between all the workers who were there when the gun was given to the officer.
I would still like to know about this picture that was shown to the co-worker and she ID'd it to be DH. And was he living out of his car? It looked like it or maybe he was just storing his "killing outfit" in the car.
I think maybe HD was just one of a number of people LE was surveilling (including the Houston guy). He never had the opportunity to dump the gun. I think he was getting ready to flee and that's why he was leaving the gun. Cashing his check and taking the show on the road makes sense if he was feeling the heat.
Based on what one of his male coworkers mentioned, the perp gave them all the impression he was taking off pretty soon. Then both the Mayor and the Chief gave interviews indicating they had the impression he was in flight and that he could've gotten away, had things not worked out as they did.
Ultimately, whatever he did or says he did and why, it seems he won't care about anyone but himself in doing so.
