This is so funny. What we are discussing is RDIs view that the R's together or in collusion, killed and staged their daughter's murder on the one hand. Then on the other hand RDI are saying that JR knew where she was or even that he moved her from somewhere else (in the house) earlier in the day, so she would be found. I'm not sure where she was moved from they haven't worked that out yet. Then they are saying that given an opportunity, (asked to search by LA) he went straight to where he already knew she was, without even pretending to search. But instead of calling for the Cops so they could see all his hard work in staging and laying out the body so it looked like someone else had done it, he picked her up and carried her upstairs. He then gave LA 'a look' that convinced her he was guilty (rather than looking like the innocent grieving father he was pretending to be). Following this, when interviewed, he described how he had found her, wrapped in the blanket and in doing so, apparently implicated himself, because as RDI ask themselves who else but a parent would do this.
All the funnier, because you don't even know this doesn't make any sense at all.
You're right: I DON'T know that it doesn't make sense, because as I see it, it makes sense just fine. These are the kinds of mistakes I would expect an amateur to make.
