There were three people in the house who could have written it. One is 9 years old and clearly did not. One is a man and the writer is a woman. It is clearly female. That is the first clue it was Patsy. The writer sat at a table with no fear of detection and wrote out the note, even throwing away false starts. The note is silly. The writer most likely was drunk and or on pills. She rambled on threatening and begging John to leave the house the next morning and not tell anyone. Never once mentions Patsy. She wants John to leave the house so she can move the body without detection. If there was some accident between the kids, why would a parent first reaction be just let her die and then I will cover it up? It wouldn't be. They would have called 9-11 and told the doctors the kids were rough housing...and that would have been the end of it. How many injuries do kids get fighting or wrestling each other in play or in real aggression? This was an adult who lashed out in a drunken fit of anger, then had tremendous regret and fear of detection. It was a stupid plan, but ". Probably due to her cancer, but maybe it predates that. John got up and reacted like a dad. He ran through the house and told her to call the Police. She finally did, but she had hoped all that rambling about if he talks to a dog or something she dies would make John just go get the money. If John had been in on it, the body would have been taken from the house, the note would be much shorter and not so silly, and then the police would be called. I think John got a better look at that note after the 911 call, then realized Patsy did this. Perhaps she confessed, perhaps she lied about how it happened, perhaps she even blamed Burke, who knows? But John decided for the good of his living family he would go along with it. It is also possible she never even admitted it to him, so he can go through life with deniability. She wrote the note. That is a fact.

"The writer sat at a table with no fear of detection and wrote out the note, even throwing away false starts."
One could even go as far as to opine that the Sharpie and pad of paper that was used for writing the Ransom Note was Patsy's own pad given to PO by John. JR was trying to be helpful. It is possible that the RN took several days of composing to get it right. JR would not have noticed it within the pad where it was written.
"She wants John to leave the house so she can move the body without detection."
Are you sure about that being a wish of Patsy's? After all, Patsy immediately called friends to come over when she finished with the scripted 911 call. In fact, I'm not at all convinced that JF was not already there, inside of the R home, as JFs car was the only car parked in the alley that fateful morning. There is no other explanation for JFs fabricated testimony that he saw and read the RN through the glass in the side door.
Spent a week in Boulder Spring, 2015. The Ramsey home is gigantic. I'd forgotten about the apartments over the garage. I always thought PR phoned a friend to place a wedge between herself and her husband's prying eyes and questioning glances. From the perspective of being on site, the Rs home was not geographically located in a particularly safe part of town.
Other than the property that FW maintains/ed, a couple of doors down, after moving to their current residence in Boulder; thereby, forming a business office for FWs19th Street property, all of the R friends live(d) on the other side of town. The Church on the corner was known for homeless people when the Rs lived on the street. Their home's very closely located to the University campus where PR took an adult enhancement art class and JAR was a student. Former Access Graphics located at Spring Street Mall would be an easy bicycle trip to the Rs residence.
"... then had tremendous regret and fear of detection"
This is exactly how PR mourned her beautiful daughter, by mourning for herself, instead. The emotion many thought was grief over the loss of JonBenet was actually fear of being caught for killing her or for allowing her to be killed.
"Patsy seems like an addicted person"
PR was high maintenance. The entire Ramsey household was high maintenance. PR colored her own hair on Christmas Day. That shows the importance of Holy Christmas Day to Patsy. PR and Nedra enjoyed "spending John's money". Custom clothing, private lessons that the dance teacher did not teach JonBenet, and PR placing her daughter in public places dressed in the non-age appropriate costumes with a sashay that the dance instructor did not show her, tells us something like a red flag waving.
PR was classic histrionic. Histrionics are in a category of personality disorders similar to NPD which is one PD that busy, busy, busy looking PR may have also had at the time. An example of being histrionic is creating drama of any kind at any time. PR was a Drama Queen, as it's said often of others, who are histrionic in personality.
