IIRC i read somewhere that a couple of guys helped her push it in the parking lot when it ran out of gas. why go to the bother to push it so it was backed in??? Wouldn't that be a lot of turning a "dead weight" car?
I've often wondered if Casey was in a blackout when Caylee was "disposed" (sorry, that just sounds awful) of. Alot of times the gates to dumpsters are shut, but not locked.
This is an interesting angle. Maybe the car did not run out of gas. They would need to find two people that potentially helped her push it. She's probably lying about everything.
So, maybe the gas cans were so she could siphon the gas out? Backing a car in that is out of gas makes zero sense. Waiting to let the car run makes little sense too. The keys were on the seat, not in the ignition. She would have had to return to it, unless it was near empty.
But, if I was going to dispose of a body. I'd get as many gas cans as I could, and fill up those gas cans with gas. Enough gas so that I could take a very long drive in the middle of the night without having to stop at a gas station and get caught by video cameras. Then I would get a lot of food and I would take a long drive to somewhere random and remote. Dump the body so nobody would ever find it, or if they did it would be a long long time. Saving enough gas to drive back. Maybe some gas left over to burn some clothes or other evidence.
Then I guess try to get the car stolen by leaving my purse and keys in from of a check cashing place where they're might be some people that need money, enough to steal the car or at least break in and give me some reasonable doubt.
