I don't understand why LA, and GA would need to be included in the DNA tests, to rule them out as matches of the hair samples. I always thought that Microchondrial (sp?) results would only match the maternal side. I guess I better do some research to be sure, but for now...I am thinking that when we hear DNA found in the car, they arn't just talking about hair samples...they are talking blood, and or other bodily fluids that will prove that it belongs to a deceased Caylee. By testing CA, GA and LA, they are only dotting their i's and crossing their t's for a rock solid case. Remember, all evidence has not been released to the public.
