Here's the motion:

At #23, the defense specifically requests the results of the paternity test. IIRC, what was in the discovery was the summary page, which the defense appears to already have, noting it by page # in their request. FWIW, I think the defense is requesting more than just the page ruling JG out as Caylee's bio-dad; they want the full testing results that support the finding, iow, Caylee's, Casey's and JG's dna profile.
I don't think they're looking for Caylee's bio-dad. My first thought is they are really looking for a specific dna profile for Caylee, rather than mitochondrial or from the toothbrush, etc. But, it could be knowing this is another item not readily available to the prosecution and that there may be a protracted battle over it, defense is just trying to keep Casey in protective custody longer. Could be they're hoping that some of JG's dna was anywhere in the car so they can continue to try to throw him under the bus as they have from the start.
Notice the defense also asked again for FBI docs they've been told are not under the jurisdiction of the court until they are in prosecution's possession. Could be just normal dotting of i's, wanting the report as soon as prosecution gets it, but I tend to see this defense, if you want to call it that, is designed more to keep Casey out of general population as long as possible, rather than attempting to free her. I'm confident that even with the dream team, the state's case is just too strong. I can't imagine any juror getting past 31 days without reporting. Certainly no juror with children would.
Besides, we shouldn't overlook the possibility that some of these experts may not come up with opinions that will be helpful to the defense and may not be called by them. Wouldn't be the first time that's happened with reputable experts whose opinion isn't for sale.
Even if they're trying to shift blame toward JG, I'm confident that will fail due to the nanny debacle. Again, 31 days. <sarcasm warning> What? JG stole her from the nanny and also the nanny's keys to the car? Or was it that Casey made up the nanny to cover for JG? I don't think even Cindy would buy that one and George wouldn't even rent it.
Finally, I think LA's atty. was pretty specific in that he was concerned about aiding and abetting or obstruction charges. These would be after the fact, nothing pre-dating Caylee's disappearance.
