Not focusing solely on your post, Charliegirl, but simply because you asked, I wanted to add this respectful caution about some photos seen on the forum. First - can someone please tell me in what program these photos of the nightgown, urine stained leggings and panties were presented? I have some reservations about all of them. The BPD would not release photos of these to the public, and it may be they are all re-creations for a TV audience. Im not totally discounting them, but unless photos are from some other reliable source besides TV, Id suggest caution in using them to enhance theories.
When a photo says Crime Scene Photo Not for Publication, its origination is from Smit. Smits photos are not reliable in that he circled items to prove his imaginary intruder. The BPD photo which shows suspicion about something on the carpet is one in which theres a square of carpeting removed by technicians for testing.
As far as JR expressing surprise about the nightgown, he did that a lot in reference to various items in the home and at the crime scene. It was his style in order to show 'innocence' or 'naivete'. He almost got away with claiming he didn't know that JB wet the bed, but housekeeper LW busted him on that, and he later revised his story that it 'was no big deal.'
IIRC, there was a drop of blood on the nightgown (info from the Bonita papers) as well as tDNA (info from Kolars book). It did not come straight from the dryer, clinging to the blanket, but was likely placed in the wc by one of them. PR finally admitted that it was JBs favorite Barbie nightgown after Nedra and PRs sister told investigators about it being a favorite.
There were at least 2 stagers, and it may be considered that PR visited the basement after JR had gone to bed and revised the crime scene, cutting the wrist ties which may have been attached to the neck ligature, thereby loosening them. If she did revisit and revise the scene, she may have been experiencing some intense emotions which caused her to change the RN to Mr. Ramsey instead of Mr. and Mrs. R which was the original beginning of the RN. Anyway, just speculation on that.
