IMO, UKGuy, JR had to abandon his original 'masterplan', because the events ended up playing out in a different manner than he had envisioned. I suspect the only reason he 'declined' the option he created in his masterplan - to get rid of the body - was because he had no choice at that point, and here are reasons why he HAD to bring up her body from the WC, IMO:
1. Arndt established she and, eventually, other backup officers were not going to leave the house - no reasonable way left for JR to move the body out of the house before decomposition and odor might give it all away. As it was, IIRC, reports said there was a faint smell of death odor already beginning.
2. Cadaver dogs had been summoned to the premises, but were being kept secured until or unless they were requested. With Arndt's experience, she might have begun to detect decomp and called for the dogs.
3. Since it was established FW had already checked the basement, and JR had disappeared for that morning time frame, if the dogs were then called in and did the 'finding', or even if Arndt had backup officers begin another search of the house for incriminating evidence when they arrived and they found her, GUESS WHO WOULD HAVE IMMEDIATELY BEEN HAULED OFF!
No option for JR but to 'find' JB himself, and immediately begin the cross-finger pointing. :moo:
ITA. Arndt went "on the record" as saying when JB was brought up there was a distinct "odor of decay". The cadaver dogs would definitely have found her. I completely agree that, whatever the parents' original plan may have been, JR knew he had to "find" her before the dogs did. SO many of the "what-ifs" in this case could have been eliminated if Officer French had simply OPENED THAT DOOR. I hope he regrets this to the end of his life. The ONLY chance for an UNCONTAMINATED crime scene- with NO way for the fibers to be innocently explained (as if there were ANY way to do that). Blown forever because of one man's incompetence. When investigating a child kidnapping (which is what he thought it was at that point- when you search the house- YOU SEARCH THE HOUSE. Everywhere, even a closed or presumed locked door- you break it down of you have to. I mean, you're he *&^%$ police! OPEN THAT DOOR!
