I think it's possible that if someone other than SA killed TH, it was them, with a little help from LE. I think that regardless, LE did some shady things to get the result they wanted. I think that there are so many factors in play that combined to get a guilty verdict, whether he did it or not.
I will try to expand on a few things...
The key being found the way it was is suspicious. Could someone in LE have put it there? sure seems like it. Doesn't mean that same LE officer killed TH.
The bones in the fire pit were not investigated properly. There is nothing that anyone can say to me that would make me believe the way they collected those remains was legit and proper. There are literally ZERO pictures of the bones in the firepit. Add to that, the barrel's. Those barrel's were also handled improperly... taken to the crime lab, brought back, taken back to the crime lab, and voilaaaaa we have human bones! If you are interested, I actually tried to follow the barrel's, there is a thread
here . Now I'm reading that there were yet more human bones in the Manitowoc County quarry?
Now let's look at Ryan... IMO the only way he could be responsible for TH's murder is if she returned home, and we don't know that she did. But lets look at his suspicious behaviour, and his suspicious calls on the Friday evening. I am inclined to think that he, maybe with a friend or family member, may have gone to the Salvage yard on the Friday night and searched the yard for the RAV4. That would have been illegal, and if it was reported that night, the RAV4 would never have been allowed to be used as evidence. It is just way to coincidental that the next morning, Pam was sent to the Salvage yard with a camera and the Sheriff's phone number. I can't say I would blame them if they did go searching the yard without permission, they were looking for a friend/loved one, but it does make them come off as shady and like they are hiding something, and if that is what happened, if they ever come clean, I think that could be legal grounds for a retrial, but I'm not a lawyer and I'm not sure.
As for "the real killer" planting evidence... if that person was also living or had access to the Salvage Yard, that person also had 3 days before LE was contacted, 5 days before they took over the Salvage yard to plant things... the RAV, the license plate, the bones. IF Bobby was there when SA reopened that gash on the Thursday night, he also would have had access to the trailer, knowledge of where the RAV was at the time, and also would know that SA was going to Menards and he had a window of time to get that blood and do whatever with it. I don't believe for a minute that he used a pipette, but if a rag or cloth could have been used (which KZ indicates in one of her answers the other day on twitter), then yes, I do think it's possible. I think KZ is cornered with the blood. From the documentary (and from previous motions), the expert didn't think there was enough of a sample and it would be to degraded to test now. SA has been saying from early on that someone cleaned his sink... he has also always maintained that he saw lights near his trailer on the Thursday, and Chuck saw some on the Friday night as well.
My opinion's are subject to change! LOL I haven't finished watching MaM2, but I have read all of the motions that have been filed up to this point, and I don't expect to see anything that would change my mind right now.
With all of that said... I don't believe everything KZ has put in her motions or has said. I am sceptical about people coming forward years later.
ETA: oh and I don't believe for a minute that Brendan had anything to do with it, or even helped anyone. I think LE needed more and they used Brendan to get it. And don't get me started on Kratz, he's a piece of poo.
