LE has a full nuclear DNA profile for Caylee, either from an item belonging to Caylee or from the paternity test re JG. They can id Caylee's DNA whether they know who her father is or not.
LE probably took a DNA sample from Casey to compare the mtDNA, or the mother DNA, of the hair in the trunk, as hair itself doesn't have full DNA. LE may have also taken samples from the other A family members, to rule out any "foreign" DNA in the trunk.
Since KC is GA's daughter, KC has half of her genes in common with GA, and some percentage, which varies, in common with LA, also a child of GA. The mtDNA would not match, but there would be alleles in common with GA and LA, KC and Caylee - they are related.
If Caylee has more than the expected half of her alleles in common with her mother KC, it could be evidence that Caylee's father was a relative of KC - since KC carries some of her male relatives DNA. Does that make sense?
My opinion, if there was any suspicion of any incest, LE would not allow KC to remain in the A household. She is very unstable, for whatever reason, and I don't think they would risk giving her that kind of defense - intimidation, scared of LE...etc.
I would normally agree with you, but LE doesn't have any say in WHERE Casey stays as long as the provisions of the bail are met because that is up to the court.
If LE had that information, they would not want it exposed yet, so they would not give the information to the court to prevent her from being in that household. As an adult she has the right to choose where she will reside while on bond. This is a court issue and not LE issue.
