Role of KK:
I know that some of you think that KK had a major role in everything. Suppose she never
initially agreed to be helpful and told PF he was wrong, but at some point he called her and said he needed to see her desperately. Suppose he convinced her to come see him- passion intrigue, the holidays, whatever and when she drives 800 miles, he says OK, I did it; I need your help; get rid of these things. She is surprised, shocked, confused and she then goes along with his requests. Too late to prevent anything, too informed to be totally ignorant, too weak to go to LE and scared. (Just a thought not even an opinion, throwing it out there.)
That crossed my mind as well but what keeps coming back is the information from her BFF that she was asked 3x by PF to kill KB.
Her BFF begged her not to go.
I think at that point any normal female would be cutting off all contact with this deranged man and letting KB know as well as LE. Then add in the potential threats and that she thought he had done it in the past as well.
If the information from BFF to the R's is accurate. KK knew the kind of man that PF was. She knew he was capable of killing. She knew he wanted her help. She knew he wasn't giving up on his idea.
If you know all of that and you continue to talk with him about murder, then nothing comes as a suprise.
You were part of it in advance, even if you didn't know the day it was happening.
If what we know is true or partially true.
