Had she stopped to think about it for a minute. Even after she had dumped Caylee on Suburban, she could have torched the car (didn't need to use gasoline, a newspaper and a lighter would suffice. Gas is very unwise accelerent to use, vapors explode, you have to be far away when you light it or you'll end up losing eyebrows. DAMHIKT....oh...alright, I was trying to get a damp brush pile to burn...doh!)
Anyhow, she could have torched the car which would have served two purposes. One, it would have destroyed a lot of the forensic evidence. Two, she could have wove it into a carjacking/abduction story, Caylee was in the back seat, this just happened, please find my baby for me, cue the fake tears. Do a Susan S. type of story, give a very generic description of 2 hispanic males and the police would have still been searching for her. Her only downfall then was dumping the body so close to home where it would be easily found. I'm mean this is Florida, uhhh hello....Everglades????
Like I said before. Good thing that she didn't think this through, there wouldn't have been any chance for justice for Caylee.
