Userid,
There may have been nasal discharge from the brain, or there may have been forensic transfer from JonBenet's internal assault. Consider she might have been cleaned up and redressed in her bedroom, so a transfer of blood is probable. Again consider the bloodstain on the white blanket, pink barbie nightgown, etc.

This is a pretty interesting and easily understood link on things to expect after and before death occurs. The blood on the pillow I think originated from the vaginal injury. Remember her pillow was at the foot of the bed not the head of the bed.
The drainage from her nose could be from a few things:
1.) She was known to have allergies. If her nose was stuffy that evening, when her muscles relaxed during death the sinuses may have drained.
2.) She was strangled with a ligature at least once. That could cause a pressure buildup in her nasal passages that released at death.
3.) She did have a severe head injury leading up to her death.
4.) She had been apparently in the stages of dying after the head wound and her lungs may have been filling with fluid as well as her throat and nasal passages.
5.) The nasal drainage could have occurred after her body was placed in the final position. It could have went unnoticed by those who staged her body because it was clearish and wet at the time. Only later drying and crusting.
6.) Blood was noted in other areas so depending on the actual spot of blood on the pillow, a blood expert could tell if it was a drop from an object, a splatter, etc. I'm sure they do know this.
I have a question. Did the Ramsey's use what we in the medical profession call "Chucks" on her bed a night to keep her from ruining her sheets and mattress?
These are disposable large sheets that capture urine and such in the event of incontinence.
The reason I ask is .... if they were found in her home, they could have easily used this item to lay under JonBenet as they wiped her down and cleaned her up. It would explain (if she was found in her room that is) why the bed sheets were pulled back so far and the pillow was at the foot of the bed. A chuck could have been laid on the bed with her on top, wiped down and redressed, and then moved to the wine cellar. The chuck could have been disposed with the other evidence. The reason I say it may have pointed to the the staging in the bedroom is this.
The supplies needed to clean her up would have been kept in or near her bedroom. Those items would normally be found in or near a kids room who suffered from incontinence. So it wouldn't have seemed out of place to find those items. (Baby wipes, chucks, etc).
But there was none found with blood or other fluids. Which means the evidence was disposed of. They had plenty of time that night to dispose of items. It's quite possible that this is the reason the lights were off outside. So no one saw movement outside.
I do not think she urinated until she was outside of the wine cellar. I think that is where the last fatal move was made. I will say again.... who ever did that final ligature in my opinion committed Murder in the First Degree. No matter the reason. Whether it was done to end her suffering or just to end it or stage it. They did it with the knowledge that it was a fatal move and did it with intent. Even staging it to appear as she was strangled.... which she was and possibly the parents thought she was already dead.....that final movement was done deliberately and during the commission of a crime. There is no statute on First Degree murder.
Test the ligature for DNA and more evidence. Regardless of who initially began the attack, the one who applied the final ligature ended her life. If that person was not BR, then they can be prosecuted for First Degree Murder.

This is a "Chuck" it is spread out over the sheet or under depending on the user. One could have been used to clean her up on and thrown away afterward.
