Bingo. Nifong HAS to establish chain of custody of said fingernails to the FA...
Yeah, I mentioned Cheshire's strong statement about the nails. Something about "Wait till you see..."
I think we may learn something very interesting about these nails.
As far as I know, there is no chain of custody since the players handled the nails a couple times before the police collected them.
The DNA of Crystal should absolutely be on the "underside" of the nail if they had been used for scratching and fell off because of how these are applied. If she dumped them on the vanity or whatever and never applied them, no sticky and no DNA on the underside.
