The area was underwater for a while, and there are also wolves, coyotes, and other animals in the area. It is possible that the item was buried at one point and resurfaced after the area was submerged. Remember the remains were already skeletonized & they didn't find plants that tend to grow where a body actually decomposed. Also like I said before GA is a former police detective & it may have been his idea to use duct tape & make it look like a kidnapping instead of a coverup of a terrible accident. Maybe he didn't bury...I'm sure he knows what an MO is & didn't want to make it look like he'd be involved. Who knows--I just know he's hiding a lot, and you don't do that without reason. Poor Caylee, rest her soul, may have died any number of ways--accidental or otherwise. I don't think ICA is innocent, but I don't know who did what and who just knew about what. Also, the only time I heard ICA say "Honest to God" in her police interviews is when she was repeating that she doesn't know where her daughter is "right now." In her prison letters, she seems to be pretty religious. That makes me think GA may have been the one who actually transported the body--which is why little evidence was left in the car, because he knew better--and ICA really didn't know where Caysee was at that point. In all her lies, I never heard to say "honest to God" during a lie; also she seemed adamant on that point, and the detectives were like "ok maybe you don't know where she is right now but you know what happened to her" (paraphrasing). Then GA &/or CA cleaned the trunk, accounting for the choloroform levels. Again, not saying any of this happened...just saying that reasonable doubt does "live" in this case (excuse my Baez-ism).
