I'm not sure the bags carried out by CSI necessarily conform to the shape of whatever is in them. They look like pretty sturdy bags, the type you might not necessarily fold all the way down to meet the contents; the type that might stay expanded at the bottom if you open them out all the way before placing something in them.
I also don't think the one bag necessarily looks like there's a handle inside near the top, either. Could be that the two bags were just closed differently (perhaps by different techs) so that one is simply folded over while the other is folded in and then rolled down a turn or two.
Not saying that some of the guesses as to what might be in the bags are wrong, just that for me, because of the variables I mentioned, it's too difficult to guess what's in them based on bag shape. Whatever it is, I hope to goodness it helps provide answers.
Does anyone know if the cadaver dogs searched inside the home, rather than just in the back yard? Seems like once the dogs hit on the decomp scent outdoors, they would have taken them over every inch of the property (inside and out). I don't recall reading or hearing anything about the dogs having been inside the home, though. Anyone else? Thanks!
