I think it's possible the door was unlocked and he was just surprised by the shooter. According to the news reports, it looks as though he only had time to sit up in bed. DS said his legs were draped over the edge of the bed, and the money scattered down his legs. Thinking he was being robbed, maybe he pulled out a wad of bills and then was shot. Dogs don't always react the way one thinks they might, or somehow Brownie wasn't a factor. According to reports, no sign of forced entry anywhere, and Brownie was inside the camper too. Brownie could have begun raising cain, and being at gunpoint KR settled him down. Unless details are brought out in court, there's many aspects we'll just never know. edit: For the accuracy of the gunshot, the shooter may have stepped toward KR as if to accept the money.
