I am thinking about the molestation and the staging to cover it up. I have mixed feelings about the sexual aspect of it. I have NO doubt that there was vaginal trauma, both chronic and acute. But let's suppose PR was regularly using a douche on JBR, whether as "corporal cleansing" (i.e. punishment) or to cleanse the vaginal canal of feces from her frequent soiling. How does this scenario sound to you:
The family returns home from the White's. JBR walks into the house (as per BR's statement). PR is tired and stressed, having had a few glasses of wine, and in no mood for JBR's crankiness, as well as having to complete preparations for a trip she did not want to make, and a very early start the next day. PR was aggravated with JBR already, as she had snubbed the "crown jewel" of her Christmas presents- the MyTwinn doll. And she had refused to wear the outfit PR wanted her to wear that day.
JBR wanted a snack before bed; she was already changed into the long johns. PR didn't really want to give her anything to eat because of the toileting issues and bedwetting, but JBR whines and so she and possibly BR share a pineapple snack. The kids go to bed. PR still has lots of stuff to do. But when she goes to JBR to get her to go to the bathroom, (interesting- that although this WAS her usual rountine, PR claims she did not do it that night- distancing again?) she finds that JBR has already soiled/wet the bed, so an exhausted PR adds the clean up of her daughter and the bed to the list of chores for the night. NOW, she must do laundry, as the soiled sheets would be sitting for the 10-day vacation.
She drags a resistant JBR into her bathroom, where JBR struggles, spilling the container of hairties all over the floor. PR uses the douche again, but this time, because she is tired/stressed/aggravated/tipsy she uses too much force, causing JBR to bleed, and JBR screams in pain. PR reacts by grabbing her around the neck, violently twisting her shirt and slamming her HARD into the sink or tub edge, maybe several times, causing the horrible fracture that causes her to lose consciousness immediately. It happens in a split-second, and her daughter is gone (or so she believes).
Though the altercation with her daughter is noisy, BR and JR, if they heard it, pay no mind because a bathroom commotion has happened before.
The realization that she has accidentaly killed her daughter sets off a panic, and she races to get her husband. He is horrified too, but as the two panicked parents decide what to do next, they do not call 911 because they believe she is already dead anyway. Instead, they decide to make it look like a kidnapping/murder. They can't bring themselves to face whatever consequences there would be to an accidental killing. PR is still in fear of her cancer returning, and BR is still young, they can't bear the thought that she'd face even accidental homicide charges. PR writes the note. They have to make it look like she was killed by the kidnappers. I believe THIS is why the Rs so blatantly violated the terms of the RN- to make it look like she was killed because they disobeyed orders and called police (and half the town).
Although they believe the blow to the head killed her, there is no apparent injury from that, so they need to have a cause of death that is immediately apparent. JBR's neck has by now red marks where PR twisted the shirt, so they decide to make the cause of death appear to be a strangulation. They use either bleach or peroxide to wash away the blood in the bathroom (which still smelled of the chemical when LE arrived). JBR is taken to the basement, to prevent BR from seeing anything if he woke up. JR carries her down the spiral stairs, and some of the fake needles from the garland get in her hair. PR's paint tote is right there, where LHP had put it before the Dec.23 party. They use cord and tape her mouth to make it seem more plausible, not realizing that forensic specialists could tell that the lips they covered never moved, snap the paintbrush in pieces, using one for the garotte. The splinter found in the vagina was put there accidentally when the one who snapped the paintbrush attempted to clean the inside of her vagina to be sure all the blood was wiped away. (some traces were found at autopsy, as well as evidence her thighs had been wiped down). The panties she had been wearing, though pulled down or removed for the douching, were stained with blood that had seeped, so PR replaced them with the identical, though different size, panties that she had bought for a niece and were also right there in the basement, wrapped up to be given. The gifts are unwrapped until the panties are found. They do not think about the size, it is just important that the panties be the same in case anyone at the White's had helped her with toileting, as often occurred, and remembered them.
The garotte had to be pulled tight enough to make it look like she was really strangled, but because she was still alive (though barely- her breathing was so shallow as to be imperceptible) the petechiae and ligature furrow occur, but they unwittingly do not pull it tight enough to cause the expected trauma to the internal structured of the throat. Post-mortem urine release occurs. There is very little urine, as JBR's bedwetting had occurred previously. The long johns were already wet from the original bedwetting. They do nothing, because they do not have another pair of the same panties, and JBR was a well-know bedwetter anyway.
They cannot bear to look at her. They remove the white banket from the basement dryer, which was where PR had placed it, probably Christmas Eve. (LHP reported that she did not come to the R home either Dec.24 OR 25th, but last changed the sheets Dec 23. She also said the sheets on the bed in the crime photos were not the ones she made the bed with, so PR must have washed those sheets and the blanket herself, leaving it in the dryer as she was too busy to put it back on the bed Christmas day.) This makes sense, as there were certainly spare sheets for her bed, but she had only one special white blanket. PR made the bed up herslef with clean sheets, but left the blanket in the dryer- this is also indicated by the look of the bed in crime photos- unmade, but the foot of the bed is neat and there is no blanket seen on the unmade bed.
They wrap JBR in the blanket, leaving her for dead. Adrenaline carries them through this horrible night. As dawn arrives, and the inevitable meeting with the pilot at the airport for the trip, time runs out and the 911 call is made at the last possible moment. Showtime.
