Is it possible he could have sent the specimens for a super-secret 3rd round of testing or is that something the defense would have to know?
It's possible, but I would think it points to anyone or exculpates anyone, they have to provide that info to the defense - the Lab results. So, it wouldn't be a surprise.
But, Nifong is specifically referring to the FIRST set of DNA testing. Nifong is saying there's something in there.
Abrams saw it. If you recall, that was the rallying cry from the Nifong supporters for a good while: If there's nothing in there, then why dont't they release the DNA report?
I think that's why Abrams was shown it - to refute those calls.
