I've gone to Fred Meyer to get soy ice cream for my autistic son and when the local store doesn't have it, I drive 30 miles to the Fred Meyer in the neighboring town to see if that one has it since no other store in our town carries the brand & flavor that my child will eat.
My point? I can believe that a person would go to a FM for something (like homeopathic teething tablets, perhaps), not find it, then drive to another FM to see if that store had the product versus going to a different store altogether (like Albertson's or Wal*Mart).
As for her 'oversharing' the timeline, maybe police asked her to write out her day and she did. Maybe the friend she was emailing with asked her what she'd been doing that day and she was not "oversharing," just answering the question asked. Perhaps the same friend asked what the police thought happened and Terri was going through different options (wandered away, abducted by a stranger, abducted by a family member) and then plugging in information that would maybe be clues for each option. I guess that since we don't have the full context of the emails, it's hard for me to judge. I also know that my personality is such that if I were being falsely accused, I would be "oversharing" to try and prove my innocence to anyone I could, so I can understand why Terri appeared to be doing the same thing and therefore it doesn't seem hinky to me in the slightest.
And as for Kaine possibly not knowing about Kyron having mini seizures or any other health issue, I can see that happening. Like others said, he had no clue about his wife's health concerns, so I don't think it's a stretch to think he'd have missed something going on with Kyron. Lots of parents are not up-to-speed about medical things and don't immediately recognize a problem at first. Also, when one of my daughters was having symptoms consistent with possible seizures, it was not considered an emergent situation. The ped referred us to the neurologist, who scheduled an EEG for the following week (it had taken a few weeks to get in with the neurologist, too). When that didn't show anything, she had an MRI about a week later. A lot of tests can't be done that same day ~ if a child needs sedation for an MRI, that has to be scheduled when an anesthesiologist is available to be there. Perhaps I'm not like the majority of parents, but I don't rush my kids to the ER for anything that isn't a true emergency, so I can't fault Terri or Kaine for not rushing Kyron to the ER once the doctor said he suspected Kyron may be having seizures.
Maybe she was setting up an alibi with the emails. Maybe she's telling the absolute truth. Time will tell, I hope.
