Can we talk about the scene at Gary and Chris's?
Both the incident report and Bobby Jo said that the front room of the trailer was covered with blood. Bobbie Jo said that it looks like they had been dragged to the back room. The bodies were found "very close to each other" on the floor of the back room (obviously moved there post mortem). And the door was locked behind the killer.
Why would the killer move the bodies to the back room? As far as we know -- the rest of the family was found in their beds. Nobody was moved. So why were Chris and Gary moved?
Also, they were the first ones found. Even though they were moved.
This has to mean something, but I can't put my finger on what it means.
