Those nude pictures bothered me from the beginning. I think Jodi took the nudes of herself by remote and she creeped up on Travis n got his pic over his shoulder. He looks asleep in the first picture and angry in the second. I think the flash woke him up and he attempted to toss the KY at her. Even Juan asked one of the witnesses if the KY being blurry was the result of the KY being in motion. I believe he woke up and told her to get out. Then he deleted the photos, thinking the monster left but she came back probably thru the window while he was taking a shower. Then she crept into the bathroom and started taking photos until he saw her and demanded she leave again but she pulled the knife and forced him to sit down for that eriee pic then stabbed him and proceeded to finish him off. I don't believe they ever had sex that day. When she got there she snooped around his office and stole the money then and got on his computer and snooped some more.
These are near exactly my thoughts also, samspace. I think it's so evident from the pic of him lobbing the KY at her that there was no sex, he had been asleep and she staged it to look like they had just finished in the pics she was taking, and he did not want her there. Also, the nudes had to have been deleted before the shower pics were taken, as those files (nudes) were overwritten (by the shower pics) and only recoverable from the unallocated space. If anyone can stomach looking at her nudes again, notice you never see her left hand in any of the pics (that would be because, IMO, as a lefty she's using that hand to snap the remote to take the pics). Anyways, thumbs up on your conception, it's what I believe as well.
I had never seen the sequence spelled out before like this, and it has never made sense to me. Yes! Finally! Now I can see it in my mind's eye.
JA was delighted (smirk) that in the interrogation Flores assumed she and TA had sex, perhaps because she wanted it to look that way and she'd succeeded in doing so. The photos were set up for blackmail, and it makes sense TA would be the deleter. JA smirked at Flores' assumption (real or a trick) that the photos showed evidence of vigorous sex activity with TA even though it potentially put her at the scene of the crime. It was like the evidence of sex was the most important goal, since that was her whole intent on taking the photos. I'm sure she also thought she could keep her alibi going by explaining away details like the timer on the camera, knowing that, in fact, the photos had been taken on a different occasion.
It doesn't seem to have been suggested anywhere that if there was evidence of sexual activity on Travis (either in the photos or on the body) contemporaneous with the murder, that doesn't mean the sexual activity was with JA. After all, there's the DIY variety. It would especially have irked JA if he had found pleasure without her. She might well have crept up on him in the bed when she first drove in, seen he was enjoying himself, gone to fetch the camera, and taken the photos. The reality that got "cut and pasted" elsewhere in her narrative was that she came upon TA masturbating and he threw something at her (or pushed her into something (the child *advertiser censored* episode?); I forget what went with what, and it probably doesn't matter, 'cos she made up all the narratives from various pieces of events); so, he was in a DIY moment, and he threw the KY at her.
Presumably, if there had been another woman (or man, for that matter) involved in some fun with TA just previous to JA's arrival, s/he would have come forward as a witness. So, I'm guessing DIY is the most likely scenario if there was evidence on TA that there had been an erection and abrasions.
Plus, wasn't there a mention of a timeline for TA "shaving" (i.e. his privates)? If he had sex with JA it wouldn't make sense that he shaved afterwards. After he thought she'd left. It would make sense if he was preparing for an assignation with someone else. This little tidbit has always bothered me.
Did the photos of JA's gaping privates come after the photos of TA in sequence or before? She could have just been capitalizing on the moment, and now that she had the camera and the compromising photos of TA seemingly right after the sex act, took hers to up the blackmail potential.
Is there any evidence of when she had to have been in the house the murder day in order to make the facts fit? Even as late as the afternoon of? I suppose she would have wanted to arrive under cover of darkness, but actually she left and returned apparently in broad daylight.
It's interesting that now trial detail isn't so all in our faces, that new patterns and possibilities begin to emerge. Sometimes detail is the enemy of reality. I'm thinking the murder day's events are much simpler than they seem and this was on the order of a tiger stalking a human, no immediate provocation of any kind, no foreplay, but cunning and slaughter and single-mindedness. Out for blood and seeking out the big mess of a bloody kill. (She chose a knife, for goodness sake; the gun was feeble and it was backup). All the detail is Jodi manipulation and a distraction from the simplicity, brutality, and intent of what went down.
PS
The Tiger by John Vaillant captures this quality about tigers, which are one of the few creatures that stalk humans "just because". I believe Vaillant's descriptions of a tiger attack gives a good illustration of what went down in TA's house that day, including the vocalizations of the perpetrator and the reaction of the victim.
