I think the significance to the comparison to Amber Frye is important in under standing the motive. Scott Peterson, like Chris, claimed he had never met anyone like Amber. He was obsessed with her. His wife, like Shanann, was about to have a baby. Until that point he saw her as a sexual, beautiful woman. But once she was about to have a baby, he associated her as more of a mother.Yep, I compared her to Amber Frey too until I saw the documents and heard from the DA that she was “somewhat forthcoming.”I think SW’s social media presence is a huge difference too. SW put her whole life on social media for all to see-including NK. I totally think several of SW’s last videos were for any of CW’s love interests to see...hoping they would walk away...but NK did not want to do that..
Nichol resembled Shanann. Maybe she reminded him of his wife before they began having children.
I believe in his mind Nichol was the woman he always wanted. He idolized her and was willing to do anything to have her. Just like Scott Peterson.
To me the relevance has nothing to do with the way each woman acted after the murder. It is the similarity in the motive, the fact that each woman played a role in the killers decision that the "other woman" was worth killing his family for.
