It's possible, but CR1's time of death was very different we now know, than in the prelim autopsies. We don't know really when KR died. We have been told he was shot once, in the right eye, so they had to get up close, and personal, in that camper.
His is the only dog that made a fuss, too, that we're aware of, that next day. DS said he knew he was home, because the padlock was unlocked. Most all articles, later stated, that there were no signs of forced entry too. I think that either keys were lifted and made, or most of the Rs all came and went, like many families, who live close to one another, and they just didn't lock their doors. But it would be nigh on impossible to get inside there without that dog hearing a lock being picked or someone messing with a door.
KR may have woke up, as they entered, or they just hollered at him and said come on in, but being held at gunpoint once they got in, would stop him from going anywhere, especially since there was nowhere he could go.
KR shot one time in right eye.

As for the necklace, my apologies, I let my thoughts run out onto my keyboard. Strictly internet rumor.
