It was a 2nd tiny spot in her panties, commingled with her own blood. I would've sworn we heard there were two others mixed with hers, but that may have been a media misunderstanding and then misreported.
If it matches some from under the fingernails, which they say it does, then maybe there is more of it, but my hunch is that if they are saying there is a lot for testing, like to give to Karr's people, it may be because it's PCR or something like that, where they amplify the sample they have by replicating it multiple times - then can use any of the "copies."
OK - well that would make more sense then. I think I need to do some reading up on the current DNA testing technology. Maybe after my morning coffee!
