Far, far too much speculation for me to comment on.
It's quite simple....I can understand why the ex and brother would want in to her messages once she was reported missing. I would do exactly the same in their boat.
It is a very, very, very different thing if they (or someone known to Theresa) did this before they suspected she'd come to harm. A VERY different thing.
You are equating the two incidents because they both involve listening to messages...but their timing makes them extremely different. One scenario is probably not suspicious, the other absolutely is.
It's as simple as that.
I'm not suggesting any of it is not suspicious to some degree. Yes, it could be innocent, and it might not. That's why you investigate.
Do I believe it was the brother. No. But if you are ruling that out, are you investigating ? no. Simple as that.
It's only a VERY different thing if you don't accept that a guy/girl would spy on a lover or ex lover.
Is it that you don't believe guys/girls do this kind of thing ? Google it. People even install spyware on spouses and significant other's devices. How would you know unless you investigated ?
You exclude it, I don't. I would investigate theories to exclude them. Maybe that's the core of our differences, in all things regarding this case.
Anyone that listens to messages before the date she is known to be missing, is going to be seen as suspicious to some degree. Simply because they have somehow gotten access to her cellphone account!
How suspicious is based on who they are and what reason you believe they had to do this.
Context : if he is not the killer
-Is it possible ex boyfriend had been monitoring her voice mail previously - this happens all the time nowadays. plausible.
-what does he do when she is now missing and he knows he has messages that are aggressive in nature on her voicmail --- he would delete them. Highly plausible.
-what does he do before it is confirmed she is missing - same thing he could have been doing for last 10 months or whatever -- listening to them to keep tabs on her love interests etc
- if #1 is plausible, this is plausible, because this is WHY he is listening to them from the start.
Context : If he is the killer
-He has the phone and likely the login information
-what does he do before she is reported missing ? -- He may listen to the messages, maybe to discover who she has been seeing etc - Plausible if the motive is jealousy etc.
-- He believes that they will think it could be her checking the messages. She is not proven to be dead yet.
-What does he do AFTER she is reported missing ? -- He removes voicemail messages from him that are likely threatening. HIGHLY PLAUSIBLE
If you are going to follow the theory that the ex-boyfriend did it, you have to then accept that she possibly wasn't even dead at this point.
The reason why I entertain this idea is because it's plausible that he would maybe monitor in this way if jealous and it's very plausible he had the means to do so.
In this scenario we also have to accept that the police likely found the vehicle and then planted it at the junkyard. Don't believe ex-boyfriend could have pulled that off easily.
But anyways, yeah, I think it's possible and should have been investigated. Defense indirectly suggested this scenario via their questioning. But just the same as avery evidence, just because the guy is monitoring his ex's voicemail doesn't mean he is a murderer. There's alot to suggest that Avery was being deceptive as well, so if we are unbiased with him, we need to be with other suspects as well.
If we believe avery can burn a cat and not be an obvious murderer, we need to also allow that a guy who is monitoring his ex's voicemail is not obviously a murderer - but suspicious.
Either way, I get what you are saying and it's plausible. I just think it's too narrow an investigation, if you exclude things I have mentioned.
We can leave it at that, I respect your opinion.
