This may be a Disney board, but this discussion is hardly about Disney. It's got child murder, incest, and a whole lot more...I don't think you can get much worse. You seem to have more information than I've read or heard anywhere, so please share.
Maybe someone else can help with information? Were there, as I understood, actually 3 pieces of tape attached to her hair, and a 4th piece several feet away? Or was it 2 and 1? And is there some kind of evidence that it was used "elsewhere" to prevent the release of bodily fluids? I thought there was no DNA or fingerprints lifted from the duct tape because of the amount of time out in the elements. I was of the OPINION (my own) that the loose tape might have been wrapped around her wrists and got free when her body decomposed and her bones were distributed by animals.
I'm still not sure what your mother has seen before...accidental drownings where the bodies were plugged up with duct tape? Still confused on that. She seems to be "in the know" about this particular type of case, but I'm still not sure in what way.
As I said, I'll wait to see what the defense says about Kronk, and what the prosecutors counter, just like the jury and your mom.
