What I don't understand about many of you is that you fail to recognise the possibility that they realised it was a lose lose situation and got the fok out of there. Why waste time with elaborate schemes of body dumping when you know you're in the shit?
They only had one chance to escape this and the time was exactly when they left. If you possess such infantile logic to think they were really that stupid consider this: if they thought they were getting rid of the body ok why the hell are they gone?
Seems fairly logical to me. Remove the body from the house and get it away in the desert. This buys a few days as it takes time to establish where the vehicle came from. Infact if that trucker had not seen it 1/2 a mile away from the road they would still be on the run and nobody would know.. (yet)
The only other option would have been to cut the girl up, bury her and sit tight whilst the cops sniffed around and that would have been very tough to get away with (not to mention do, as cutting up a body has to be a pretty horrible thing to do). One minor slip up and that would be it, as there are no second chances to make a run for it once you play your hand and stay in your house and deal with the police.
I realise that this is a long post and somewhat dispells your fantasies that you can think better in that situation but you're all douchebags with no true flair for logic.

Lolzors, I am leaving this post because it was beautifully written by a mind of logic, I have since learnt that Titus stayed and was questioned about his car. He really is that stupid! What a dumb shit!
