I can try to answer some of them.
She is alive BOTH when she is strangled and when she is bashed. The petechiae occur only while alive. The petechiae in her eyelids is a standard finding in strangulation deaths. Because of the urine stains on the front of her clothing, as well as the bruise on the back of her right shoulder, as well as there being green paint flakes on her chin that match those found on the basement carpet near the paint tote, I see the cord being knotted at the back of her neck while she lay on her stomach on the carpet near the paint tote in the basement. The urine release there tells me she she died right there. The head bash may have happened elsewhere, as did the sexual assault.
Many have tried to understand why the garrote was needed at all. We will never know. If it was a sex game, and she screamed and was bashed during it, that does explain both. Otherwise it had to be staging. Remember that the head bash left no VISIBLE signs- no bleeding, no scalp gash, no facial swelling. In fact, those present at the autopsy (including the coroner) were allegedly shocked when the coroner pulled back her scalp and saw the hole and large crack in her skull. So they had a comatose/dying child with NO indication of how she got that way.
Say what you will about the parents- I simply cannot see them putting their daughter outside for ANY reason. As far as letting the cold "finish her off"- I cannot see them leaving her to freeze outside. I can't see them planning to dump her out side for ANY reason, whether they planned to get her later or not. That is why the way she WAS found has "parental involvement" all over it. An intruder would have left her in plain sight, a shocking "gift" to JR under the Christmas tree or something equally as repulsive. Thanks to Arndt, she ended up there anyway. As far as calling 911, they DID wait till the next morning.
If her underwear became too bloodied, it would have needed replacing. The FACT that the coroner found that her thighs and pubic area had been wiped indicate this may have happened. They were trying to HIDE the sexual assault and previous abuse- an intruder would not have bothered to wipe her- the blood only adding to the thrill. Nor would they have needed to change her panties or known where the size 12s were.
BR didn't play in the wineceller, and JR said the little wood latch at the top of the door (that prevented the first cop on the scene from opening the door, thereby compromising the crime scene forever) was put there to keep the kids out. That was not a room for play- filthy mold on the floor, and only paint cans and window screens, etc. The train room was where he played.
I feel they intended to hide her in there until police left and then they'd figure out what to do. When it became obvious that police were NOT going to just leave them alone in the house, JR had to "find her". They made sure they got BR out of the house in case someone else did first. They always planned to remove BR from the house that day. This way, he couldn't be observed, questioned, or present when JB was found.
The "large" panties don't protect anyone. That wasn't their necessity. They were needed to replace panties she already had on- nothing more. They were worn UNDER her longjohns, and were never worn while she was alive and like the skull fracture, the size of the panties were only discovered when she was undressed on the autopsy table. The parents never imagined they would become an issue or noted as unusual because under her longjohns, they WEREN'T unusual. So the SIZE of them had nothing to do with protecting BR per se, but to have her found without panties might signal a sexual assault.
Denying the pineapple was important because they had already told LE that JB was asleep when she got home, they carried her to bed, and they never saw her awake or alive again. Admitting she ate the pineapple means admitting they lied about her being awake. Simple as that. By the way, it was BR himself who told LE his sister was AWAKE and walked into the house that night.
Like the too-big panties, the parents NEVER thought pineapple would be found in her digestive tract. So when it was, they HAD to deny it, and they also tried to deny even owning the bowl, spoon, an box of tissues near it! It also follows that they could not even say that BR MIGHT have had pineapple with his sister unbeknownst to them. THEN- police would definitely want to talk to BR more extensively. And suspicious would be raised about what ELSE he and his sister had done that night. It also brings it all too close to the time of death. If he was awake eating pineapple with her at that time of night, the intruder would be walking around with him awake and about himself.
JB was never salvageable. By EVERY forensic specialist's account, including the coroner, she'd have died of that alone. She would have instantly collapsed unconscious, probably having seizures (mucus and vomit on the cheek, evidence of tan mucus in the nose) and maybe comatose, certainly in shock. Shock lowers the body temp and suppresses breathing- she may have appeared dead to them. So to them it was a fatal event that needed covering up, regardless of which R was responsible.
You cannot seriously think that NO tests would have been done on her if brought to a hospital? A simple X-ray would have shown the skull fracture. This was a catastrophic injury. She'd have been in a COMA in the hospital, and her death from that bash was INEVITABLE. She would NOT have been "treated and released". Having been examined, the parents would have been arrested as soon as the bruise on the labia was seen, and then they WOULD have done a pelvic exam with speculum and seen the eroded hymen and blood and internal bruises. She would not have survived. And in EVERY State, ALL dead children are autopsied.
Bottom line- there was never going to be a LIVE JB. She was going to die. That night. Whether they took her to a hospital or not.
Apparently medical records of the deceased are confidential too, even if they are needed to solve the murder, IF you know the right people or have enough money.
By the way, NO medical records are confidential if a warrant is issued for them. This happens all the time in REAL DA offices.
There would be no charges against BR anyway, no need for a plea bargain. I am even thinking that psychological help would not be court ordered if it in any way might have implicated him in the crime.
