I think the attorney's assistant would have gone out and bought a phone for Terri if it was Houze's idea. I don't see why he'd have thought it prudent to involve friends in the operation.
Regarding the cell phone hacking, I think it's a completely unnecessary assumption. I feel that I'm required to bend over backwards too many times to make Terri squeaky clean in everything that looks even slightly off color. We would have to make so many other people to be in the wrong to make her right, and for what? Whatever your sexual morals are I think we can all agree that it is not illegal to send out dirty pics of yourself if you're over 40, so why would someone need to frame her for sexting and why would we need to prove her innocent of doing it?
Either we have to assume the existence of a cyberstalker with up-to-speed hacking skills (not verified) who (we further have to assume) sent those photos pretending to be her, apparently to frame her for sexting (not a crime in Oregon afaik and it does not prove she knows where Kyron is so I don't know what would be the point), or because the cyberstalker had a desire to get MC involved in the investigation for some unknown reason (all just speculation because there is not a shred of evidence for any of this that I know of).
We would further have to assume that Terri and her lawyer have not heard about any of this because I think she would report a crime if someone unauthorizedly used her identity and hacked her cellphone to invade her privacy, destroy her reputation (especially in the light of a possible court case coming up) or sexually harass an innocent high school friend of her soon-to-be ex-husband, and I have not heard of such an investigation taking place.
We would further have to assume that the LE people investigating her phone records and other people's activities are completely clueless about it (unless they have some hacking charges coming up shortly).
Or we have to assume that Terri sent those sexts to the named sexting partner (as stated in the court records) who has admitted taking part in the sexting activity, (as stated in the news).
I don't understand why we'd need to bend over backwards to prove that Terri didn't send those sexts because she has so far not even denied it herself (afaik), nor has her lawyer. She may have sent them and so what? It is not proof of a crime. It is not proof that she did anything to Kyron. At most it can be said that it goes to her state of mind after Kyron went missing but a good lawyer could spin a reasonable argument that she was just so alone and abandoned and devastated because of all this, needed some male comfort and her judgement was slightly impaired because she was so down because of Kyron and the false allegations Kaine made.
If we suppose that it's Kaine or MC doing the cyberhacking, it's noteworthy but a bit incongruent to me if we need to assume the guilt of other people without any proof or even suggestive facts to support it, in order to keep an open mind about Terri being innocent until proven guilty to any allegations thrown her way, while it looks like there is a GJ convening, possibly to determine if they could indict her.
