Which is why they should look at friends and family, yes. Not ignore other possibilities. Isabel Celis, Jacob Wetterling, Lindsey Baum were all abducted by complete strangers after all.
You're talking about an email that has never been proven to exist, never spoken of by LE, and the very existance of which makes no sense whatsoever.
Yes, Desiree obviously (and understandably) harbored a lot of resentment towards Terri. It doesn't have to be a conscious thing, but it certainly is something that can cloud your judgement and interpretation of statements and events, especially in a traumatic situation like this.
I also don't know what she said to the police, but she did say what made her think Terri was lying:
She was wrong about the stairway. And the "dropped Kyron off" bit is a good example of the bias I mention above.
I mean, that just goes to show how weak the case against Terri is. Kaine is putting most of his emphasis on the polygraph tests, which we know are unscientific and utterly useless in determining guilt or innocence. The rest is him reading into her words and behaviour. A lot of people genuinely believe that polygraphs are lie detectors, and when those fail, they get the erroneous belief that a person is lying.
Failing a polygraph isn't your own action. It's bad luck.
It's interesting that I just read a defense of the Perugia police for their hyperfocus on Amanda Knox, arguing that they still questioned other suspects and looked into other leads. Tunnel vision is not a black-or-white issue, but exists on a spectrum. It can make it easier to dismiss or disregard the other leads you get.
I don't know just how the MCSO worked, but what little info has seeped out has me less than impressed. And I do believe the results speak for themselves.
If so, I think it was highly irresponsible of Rebecca Morris to name the classmate in question. But it does come with problems of its own. For one, if the sighting was at 8:50, as Desiree claims in the Morris book, what on earth was the classmate doing in the parking lot? The bell had rung five minutes earlier, he should be in the classroom, shouldn't he?
And another, the classmate actually did speak to media on several occasions, including
here:
But this kid supposedly saw Kyron leave with his stepmother an hour earlier.
Yet the other parent has rights too, don't they? If they have evidence she removed him from school (the hypothetical email, supposed witness sightings), then I doubt there was nothing they could do legally in regards to Kaine's parental rights. I could be wrong, of course, but I'll leave that to someone more versed in Oregonian criminal law.
But this again stumbles on the increasingly convoluted theories needed for Terri's guilt. If she told everyone and their mother at school that she was taking Kyron out of there (and an email confirming this takes it out of the realm of unlikely and into fantasy), why did she attempt to hide it from everyone outside the school? It's Schroedinger's Kidnapper - depending on the outcome we need to maintain belief in her guilt, she either attempted to hide her tracks or proclaimed her intentions loudly.
It just seems incredibly irrational to me.
Yes, someone saw a white truck on the access road. No evidence it was Terri's, but that's obviously what the police believed.
But as has been amply demonstrated with pictures, it would be just as visible from the parking lot entrance if the truck was at the shoulder of the road or a few yards up the access road. There's also the matter of the baby, who Terri carried with her all morning. Did she strap her in before killing Kyron, or after? Either way, it is an incredibly poor choice of place to commit a murder.
Which is an absurd question on its face. Kyron was in the truck with her - when she drove to school. Just more proof that polygraphs are bunk.
