So, someone, not Avery, kills Halbach. The ex gets the key (how, I don't recall), then gets it to the police so they can frame Avery? Why would the ex do that, unless he was the killer? The police then get some blood on it (again, not sure how) and plant the key? And if the ex is the killer, then when and how did he do all of the moving of the bones onto the Avery property, and the Rav onto the Avery property. I though Tadych was the killer, with Bobby Dassey, because of all the bad porn on his computer and because they supposedly lied about each other's alibis?
