I wonder if lets say you made a big batch of chloroform in lets say a GAS can, and it is constantly in a closed environment like a trunk of a car, applying duct tape to a little girl, the little girl is alive but weak and dazed from the chloroform. The duct tape over most of the nose area too but the little girl had enough air until the intoxicating levels of chloroform was too much of a stress for the little girl's body and she died. The Chloroform would keep the bugs at bay or kill them (Casey I'm sure went to a car wash place to vacuum the bugs out). The stain could it be caused by the plastic bag, the decomp along with the chloroform basically like a burn in the carpet that caused the stain. Not a burn per-say but it caused discolorations, the bag was black.
LP theory on RK is crazy! There were active searches going on, if this was the case, one of the search teams could have been tipped off to go there, police could have done that on their own with a cadaver dog. LP went early on the crazy theory and now locked himself in. He be better served to announce his theory is flawed and just realized that.
This Godmother of Caylee (forgot her name) will probably be called by the DT and the state is waiting. I believe this woman spoke to the police about it. I heard the audio recording and she said she talked to Casey on the phone, and thought she heard Caylee in the background on July something. If the DT doesn't put her on, you know they fear her. I believe this person didn't hear Casey but some other child while Casey was in Target, Win Dixie, JCpenny, or gosh knows where. Casey Cell phone pings and this girls cell phone time and date of call can match up and prove where Casey was at the time.
