Dr. G never said it was prior to death, she said it was prior to decomposition.
That is true, but that's exactly why I find her testimony unconvincing. The prosecutor's theory is that the tape was the death weapon, and Dr. G's testimony did not support that theory.
But there is no evidence to support Dr. S's theory, about tape being applied after decomposition, and it is refuted by plant growth entwining tape, hair, skull and jaw [indicating tape was applied before decomposition]. It also makes no sense -- I can't imagine why, after decomposition, anyone would tape the jawbone to the skull.
But, as many others have pointed out, there is another plausible theory, besides the prosecution's, that accounts for all of the evidence: the tape was applied after death, as decomposition was beginning, to prevent the leakage of fluids through the nose and mouth as decomposition began. For me to accept the prosecution theory regarding the cause of death, I would need evidence ruling out this alternative, and there is none.
I am withholding my judgment on the defense theory of accidental drowning until the defense rests. But I know this -- the defense would have had me leaning its way had this been its theory: Casey discovered Caylee's body in the pool. She panicked and put the body in the trunk and, a few days later, when the smell became too powerful, she dumped the body in the woods. Her partying while her daughter lay rotting in the trunk was due to her coping mechanism of pretending everything was OK when it was not. [I would not need the molestation story to prove her tendency to deny reality she did not wish to confront -- it's undisputed that she pretended to go to a nonexistent job every day for years, a behavior I find almost as chilling as her driving around with the body of her dead child in the trunk].
By injecting extraneous issues [eg. sexual molestation by George; George associating with a convicted kidnapper; Kronk being involved somehow in how the remains got to where they were], and silly claims [denying the body was in the trunk even though their own entymologist said the car had the smell of decomposition two years later; someone taped the jaw bone to the skull], the defense is forcing the jury to choose between the defense's incredible theory and the prosecution's credible but unproven theory.
