Hmm. There is that. There is also the fact that they stated that LE had nothing to do with their PC. I think that speaks to frustration at what they cannot say. What they have been advised not to say.
MOO
What might they be holding back, though? LE has, IMHO, leaked most of what there is to know. This is where my reasoning is a bit circular. If there was overwhelming evidence against Terri, she would be in jail. She is not in jail. If they had overwhelming evidence against her, why would LE tell KH that this is going to be a marathon not a sprint? Overwhelming evidence = sprint, lack of overwhelming evidence = marathon, IMHO.
And this is where I see circular reasoning between LE, DY, TY and KH.
LE, DY, TY, and KH have repeatedly stated there is no evidence that Kyron is deceased. This tells me that there is no evidence of a murder. This means LE has no evidence against Terri that implicates her in a murder.
We drop to the lesser charge of Terri abducting Kyron. By their own admission, LE interviewed hundreds of witnesses, including parents and children, in the days after Kyron went missing. If there had been a smoking gun such as a witness who saw Terri shuffling an incapacitated Kyron into the truck or otherwise leaving with him, they would've found this witness by now. When LE sent out the questionnaire
after they'd interviewed hundreds of witnesses, this told me that they had no evidence Terri left with Kyron that day. If LE had witnesses attesting to the fact that Terri left with Kyron the day he went missing, the questionnaire would've been unnecessary. And let's not forget that the questionnaire went out to the hundreds of people who had already been interviewed. If there was a witness or witnesses who saw Terri leaving with Kyron, I truly believe we would know it by now.
The cell phone pings. Again, I am not an expert on cell phone pings, but it's my understanding that they give a range. Terri was, admittedly, out and about that day, and so is it possible her cell phone pinged off a tower as she was running errands? FWIW, I believe the cell phone ping information is accurate insofar as it places her somewhere she says she was not, and I believe this is key in DY, TY, KH, and LE's assertion that she is lying.
The failed polygraphs. Eh, on polygraphs, but we'll go with she failed, as reported, "a key answer." That indicates one answer, which is bizarre to me; it is nearly unfathomable to me, if she did this alone or with an accomplice, that she could only fail one answer if the report of her failing "a key answer" is true, and I believe the report is accurate. Only LE, TY, DY, and KH would know whether or not she failed, and so whoever leaked the information was privy to the information. I don't believe they'd make it look better for her. If she failed the entire polygraph, or multiple answers, I believe the leaked information would reflect that failure, e.g. "She failed multiple questions with regard to key areas of the investigation."
So, IMHO, what LE have is the cell phone pings and the failed polygraph, LE's focus, and DY's suspicion. The pings and polygraph being the only evidence LE have makes sense to me -- polygraphs aren't admissible, and cell phone ping information isn't enough. If there was anything solid, Terri would be in jail, IMHO, and if there was anything else, LE would've leaked it by now, IMHO. Everything else -- the pings, the polygraph, and the mfh plot have been leaked, the latter despite everything being sealed.
