I am in the camp he is guilty but the police were also responsible for planting evidence. It almost to me seems that both sides, starting with Steven Avery, were playing a game of cat and mouse. What I mean is, I believe he murdered her, parked the RAV4 in a manner which would seem like someone was planting evidence, and then he tried to burn the evidence (the body, her camera, her cell phone, and any other personal artifacts). He had 18 years in jail to fester and stew a response to a crime he knew he did not commit. Why not try and seek revenge on the Manitowoc County Sheriff Department? Make them look even worse by locking him up again for a crime he "did not commit." Little did Mr. Avery know that burning a body in a fire pit would not be enough heat to disintegrate the body.
Enter in the Manitowoc County Sheriff Department. They come on to the property before obtaining a search warrant and notify the search party that her vehicle is on the property and the location of it. Upon obtaining a search warrant, no key is found until Lenk plants the key that was found most likely when they entered the property without the search warrant, or it was a spare key from her house, provided to him by the roommate in exchange for leaving him out as a suspect. Because you know, reporting a missing roommate four days after she has gone missing is not suspicious.
Who punctured the vile of blood? I don't know. I do not think the taken blood was used, given the lack of the EDTA (though at least one article claims to offer an explanation for this
A Scientist Explained Why The Blood Evidence Used In ‘Making A Murderer’ Is Complete And Utter Garbage). His DNA being present in the form of sweat on the key and the hood of the vehicle is suspicious. Obviously it points to him handling those items. I would imagine chopping up a body would make you sweat.
For those who think Steven Avery is innocent and worthy of a pardon, would you want him to be your neighbor?
Edit: Len Kachinsky is also a piece of shit.
