Imo thats because LE doesn't know Terri as well as Kaine and Desiree do.
On the contrary, the interview about the content of the emails is very telling to me. They may well know 'why' but choose to not share it publicly. And even if they don't know why, the fact remains that she is not talking or cooperating with the investigation. If she is truly innocent, she would be doing everything possible to tell what she knows. She will never do that.
Okay, pictures. Have you thought about the fact that she only took shots of him when he was happy or 'smiling for the camera'? Or she only chose to post the 'happy' ones on FB for obvious reasons? Just because we don't see 'unhappy' pictures of Kyron doesn't mean they don't exist, for obvious reasons.
Thank you. Happy pictures doesn't mean a happy life. Casey Anthony had TONS of happy pictures of Caylee and her friends were all shocked when Caylee died because they couldn't believe that the Casey they knew would do something like that. And the whole time, she was lying to everyone and really resented the heck out of Caylee for taking her place in the family. Who knows what went on when they were alone. Even some creepy home movies have come out that Casey filmed and she doesn't say a word the entire time. The poor child is wondering why mommy isn't talking to her and even gets upset.
My point is, it's easy to fill up albums with happy pictures to convince people that your family is perfect and there is nothing wrong. You could say the same for my family. If you judged us by our albums, you'd never know what a hard time I had growing up with a mother who was a perfectionist and never accepted me for who I am. Pictures only capture moments in time, they don't capture EVERYTHING that goes on. And people can easily fill up albums with only happy pictures so everyone who sees them will think that their family is a happy one.
Who knows what happened to Kyron when he and Terri were alone. I keep hearing she loved him so much, yet she's never shed one tear for him, or plead for the real perp to bring him home. She hasn't SHOWN once how much she really loved this child if she did, and I don't think she did.
Her motive, to me, is that the perfect and loving mom mask was getting harder to hold up as Kyron got older. She wanted everyone to think a certain way about her, but Kyron was getting in the way of that. Maybe she was afraid he was going to blow that mask off of her by telling his bio mom about something that happened to him, something that Terri did to him. I think it's no coincidence that he went missing on the day he was supposed to go to Desiree's.
I think Terri was more worried about what he would say to Desiree because Desiree was more onto the real Terri than Kaine was. Who knows, maybe Kyron had a bruise or something, a tell tale mark that would let Desiree know her fears about Terri were right. Terri couldn't risk her perfect loving mother mask being shattered by something like that. If Desiree pressed charges, everyone would know Terri was lying about being this great mom. Or maybe she feared that Kaine would believe Desiree that Terri did something to Kyron, and Kaine would divorce her and then everyone would know what a bad mother she really was. I mean, Kaine has said that Terri was worried that people would think badly of her. She can't stand the thought of people not seeing her as the perfect mother. She had fooled them for a long time, but this mistake would cost her her reputation, and some people just can't deal with losing reputation. They'd kill to keep their perfect reputation intact.
I think she killed Kyron, planned to blame it on the school so her reputation as a perfect and loving mother would remain intact more than ever, and she'd be rid of the one thing threatening to reveal her true self to the world, and maybe even get the double bonus of Kaine committing suicide so she and the baby would get all of his money. She'd never have to work and would live the high life she's always wanted to live without working. But things didn't go her way at all, and I think the last thing she wants is Kyron found, which is why she hid him so well.
And who knows, maybe the shocking thing is that they have investigated all alternatives and haven't turned anything connected to Kyron. Maybe the shock is that the perp really is Terri, and they just need time to get enough evidence to get her convicted. Honestly, the police see and expect bad things everyday. I don't know how shocking it would be to find out some sex ring was involved or underground getting kids away from abusive parents. To me, it would be shocking if they looked into all of that and nothing came out of it, or they found out about it because it stemmed from people Terri knew, but it wasn't related to what happened to Kyron. I honestly don't think they went into this believing Terri was the perp. I think they thought even if she looked suspicious, that they'd probably clear her, this middle aged middle class SAHM, and the shocking thing is, she's not what they thought at all, and even more things have stemmed from who she knows and associates with. And the other shocking thing is, it's looking more and more like Kyron is dead and is not alive and being held by someone. I don't think Terri would risk her reputation on someone else holding Kyron and either turning her in for it, or letting Kyron come back and he would be the one to get her into trouble.
