I agree with you 100%~ We have another poster here who knows Kat and has stated that Kat has lied on the stand about never being with a woman~ She also states seeing/hearing about her shortly after the incident and she was anything but "distressed".
I do not know Kat but I am familiar with Seth~ after hearing from our poster about Kat, speaking with some of Seth's friends that have met Kat I am really starting to lean towards the story that Kat gave in the beginning~ Reasons why;
1. Seth confessed to doing everything from killing her to dumping her in the water~ Kat has testified that she was the one that thought up the suitcase, the duct tape, turning off the phones, where to dump the body etc....
2. The wire conversations, same story, same everything
3. The searches on her computer, her online presence, her lying on the stand that she had never been with another woman
4. Seeing/knowing Seth, he is an introvert IMO... I always thought that if a woman ever said boo to him he would run the other way. I never saw a passive aggressive attitude from him~ I saw him in a romantic role and as a director with one of my good friends~
5. Being in the courtroom, speaking to friends of both of them, Lizzie was not IMO controlled, I think she was the controlling factor in this relationship~
I am not on the fence at all but I do think that both of them should be held accountable for their actions that evening.
