The early off-the-cuff comments by the Ramseys, before they lawyered up, seem to indicate they know who killed JonBenet; it was more than one person involved; but they haven't yet figured things out as to WHY. For example:
In regard to John, PMPT pb, pg 54: "I don't get it, he said over and over. Then he got up, walked outside, shook his head, and asked aloud, WHY?"
In regard to Patsy, PMPT pb, pg 53 (Patsy talking to Pam Griffin): "You know, they've killed my baby." Pam noticed Patsy used the word 'they'.
"Patsy said something like 'We didn't mean for this to happen', Pam would say later."
"Later, Pam couldn't say why, but she remembered feeling as if Patsy knew who killed JonBenet but was afraid to say."
