From the first episode you feel a biased toward the convicted killer. I've listened to several lengthy podcasts about this case, all seem to lean one way or the other. One thing that is undeniable is she was convicted of 1st degree manslaughter, judge gave her a long sentence due to her complete lack of remorse. She is the only one directly connected to all the important evidence, all the evidence she has in her favor are theories & statements from people who only came forward months after Mary died and only when Katie was charged. The police did first look at Bill & Adam. Even though it was Adam's Jeep & it was a mess none of his dna was on package or bottle but hers was, she denied in trial that she wrote the letter, but admitted it in docu.
In my opinion is she guilty, this documentary leans towards her innocence yet only a person that didn't know all what think she's been wrongly convicted. She is guilty, she has those evil eyes, that shark look, every killer has it. This is an attempt by an important family to further her appeal efforts since none have been successful as of yet.
I don't believe Katie, I've listened to the interrogation tapes, her lies, flip flopping, her notes app had a ton of incriminating evidence, the evidence against her is massive, that's why she was convicted. The first trial only ended in mistrial because they couldn't decide on charge all thought she was guilty.
