Early on, I was much more suspicious of Terri and believed it was possible she was involved in some way, but with the passing weeks, I've grown more skeptical about whether or not she was involved at all.
IMHO, Desiree has convinced a lot of people that Terri is guilty. I say Desiree because she has been much more vocal, and she is compelling as a grieving mother. Obviously, Desiree is destroyed without her son, and you see it on her face and you hear it in her voice. This is very important in my reasoning, but one thing I've taken away from the press conferences is that Desiree believes Terri is capable of abducting Kyron but not killing him, hence why she believes he's still alive. Deep down, I think Desiree knows Terri loves Kyron, which is why even though she believes Terri is responsible for his abduction, she can't fathom that he is dead. Desiree needs Terri to be responsible in order for this prophecy, Kyron being found alive, to fulfill itself. Desiree's husband is LE, I'm sure she's heard the stories, and even laypersons know the likelihood of a child being alive if taken by a sexual predator. Terri is her best suspect because in Desiree's mind, she's the only suspect who can be responsible and yet Kyron still be found alive.
Also with regard to Desiree, I believe she's never liked Terri, perhaps with good reason, and her dislike of Terri is influencing her interpretation of Terri's behavior to the extreme. IMHO, Desiree is a key reason why Terri has been found guilty in the court of public opinion, and perhaps even within Desiree's inner circle. Who's going to argue with a grieving mother? Who's going to tell her she's wrong when her son is missing and likely dead? And, in addition to that, Terri has behaved in ways that make her appear suspicious; however, having said that, I also believe there is a lot of misinformation out there about Terri and that day.
I hear a lot about instincts and what is viewed as odd behavior, but if you're looking for it, you're going to find it, IMHO, and Terri hasn't exactly helped herself in this regard. IMHO, if LE had a lot of evidence, Desiree wouldn't be talking about her instincts and odd behavior. The lack of evidence in this case is baffling. I don't believe LE has much in the way of evidence, certainly not a murder scene. After so long of looking at Terri, and still not uncovering much evidence, I have to wonder if they're looking at the right person and in the right places.
