In the docs released regarding the finding of the remains, it described how the skull and hair were found. The person filing the report said the skull was upright and facing a direction, some hair was still attached to the skull and on the tape that was in the mouth area, and there was hair on the ground all around the skull. Going by memory, so don't have a link, but it is right at the beginning of these docs discussing the remains. This hair would be considered part of the remains, it was a lot of hair, not just a strand or two. While I don't have documentation stating specifically the bones and hair were turned over to the defense, the defense did a second autopsy which wasn't really an autopsy since it was skeletal remains. There were also teeth found not attached to the skull, and like the hair, I am guessing those would be considered part of the remains as well. So, going by all that, I am willing to bet the defense did have plenty of hair turned over to them along with bones after the state was done with their examination.
I also believe we are not privy to every bit of discovery given to the defense. It's like the pictures of the remains, those are not going to be handed over to the press, and it seems some of the other stuff is not, as well. We know by what has been released there was a lot of communicatiton between Casey and TonE the night of June 15th and early morning June 16th we haven't seen, and we probably won't until trial. I am also willing to bet if that stuff has not been handed over to the defense by now, we would be hearing motion after motion to have it turned over.
