So who is covering up for who?

The case is crazy because it doesn't add up. There is the truth of the body and the scene. Then there is the testimony of Patsy, of John, and of Burke. It seems implausible that everyone in the home did not know what happened to JonBenet.

Did John Ramsey sa his daughter and then Patsy came up with the ransom note?

Did Patsy Ramsey sa jonbenet and then come up with the ransom note and cover story?

Or did Burke sa jonbenet and the parents both came up with the ransom note and cover story?

To me it seems like Patsy must have written the note. Its not just the handwriting, its the craziness. It doesn't sound like Burke or John. But that doesn't tell us who killed jb.

The garotte strangulation and the vaginal assault seem like the rage and domination of an adult male. I can see JR keeping a secret for the rest of his life. I think BR is too fragile, so he might not even know what happened, Or he didn't at the time.

Everyone is lying here. But lying doesn't mean someone committed homicide. I just think its Patsy who is covering for John. What do others think?
