I do not understand this either, especially if high readings were found. To me it also goes back to some type of cover-up, to blame this phantom nanny or whoever else could have taken Caylee other than the accused. I look at it this way, imo, the duct tape, the chloroform, the purse in the car and all the other little etc's., it is almost as if some type of set-up was going on to blame anybody else even an unknown person IF the car was stolen from Amscot as the kidnapper. Just seems alot of things were placed to sway attention off of this family-in their mind, but it didn't work, just made it worse. Imo, I think Caylee died in the home and the rest; tape, chloroform, decomp was 'used' to support the kidnapper theory. Don't be angry about the decomp I mentioned, I mean it doesn't seem to me Caylee was in the trunk for a long length of time and then ica found her and the uh oh happened. I think she unfortunately was in there 2, 3 days at the most for sad to say transportation purposes.
