I've never believed the backpack location was an attempt to throw off LE. I have always thought this killer is too narcissistic to have wanted too much time passing before this was acknowledged as his handiwork.
All the remarks he made after the crime reinforce this for me.
I also think his breezy explanations don't quite get at devil that's in his details. Of course LE may not be releasing all they know, but these shifting stories about he just grabbed her, tried it this way, then that-a-way, then took her to his bedroom, killed her, then happened to find a saw and dismembered her in the family bathtub, to me, sound like part of his manipulative game. I'm sure there's truth in his confession, I just don't buy that he's telling all of it. And I've always thought his statements are an extension of his desire for attention to his deed.
His question to LE about whether it would give the family peace to know he did it and will be accountable, in my view, is akin to an acceptance speech at the Oscars. He doesn't give a whit about that family, he merely wants credit, and his remarks are passive aggressive manipulations as far as I'm concerned. It reminds me of the old movie Sunset Blvd. where Gloria Swanson's unhinged actress character comes down the stairs of her creepy mansion after she's killed, asking, "Is it time for my close-up?"
He felt sick. Mmmm...sure. As in, once the fun and fascination part was over and the ugly part began to slam around in his memory with less enjoyment on his part, he needed another release, this time to dump his toxic feelings. So he confessed. He's an immature predator who acted on his instincts and it didn't turn out to be as satisfying as his fantasies.
Maybe LE knows the rest of the details, but I don't buy that the story we've been reading about how this happened is all that happened.
Not only that, use of a saw sounds like an extremely time intensive and messy labor to me.
How on earth did he manage to clear that deck by the time the family came home and when did he dump her torso?
Not buying that his confession is quite like it really happened. Especially the part about how he kept her quiet in the car and on the way to the bedroom. That part is conveniently missing, just as the part we previously read where he managed to just whisk her into the car, hog tie her, and kill her right there on the street, then drove on, and somewhere along the way she ended up in pieces, part of which were abandoned in open space. Bada bing.
Not buying it. He sought a victim and I don't believe for a minute that he just kinda happened on a saw after he went 'Hey there's a kid I could just grab and hog tie, maybe choke, maybe strangle, then dismember in the tub'.
