I still think we can’t get into NK’s state of mind, and I can’t help but feel the shock, disgust and horror she must have felt about the intimate parts of herself she shared with that monster, CW and why she’d want to erase any connection with him and what they did together ASAP as a woman, without giving any thought to a police investigation. Maybe I’m wrong. She didn’t delete her texts about CW to her friends which you think she would do if she was trying to impede the investigation. As it turns out the police were able to take the information NK gave them, without the texts, and walk into that interview room and coerce CW into confessing, and with NK’s consent, were able to download most of the deleted texts.
