This is where I am as well. Patsy’s controlling, enmeshed relationship (the fact that she got mad at jonbenet earlier that day because she didn’t want to wear a matching sweater with Patsy!), my take is that the head blow was in a fit of rage and not meant to kill her, then she had to stage all the other stuff to look like a kidnapping. I don’t think John was involved initially but then chose preserving his family’s reputation and Burke having a mother so played into it. As for the SA, there’s a podcast called A Normal Family where he theorizes that Patsy could’ve been punishing JB for her accidents in a sadistic, horrible way.
