I wanted to bring up a quick point that was mentioned by Hardy. He said they had found gator fingernails while searching. I have only seen gators in zoos but I am assuming that they would be rather small. It makes me very confident that if they were able to find something as small as alligator fingernails that they were able to possibly find HaLeigh's remains as well.
Rest in peace, baby girl. We never gave up looking for you & we won't give up until you receive the justice you deserve.
Depends on the size of the gator. I live in Florida, and some of those gators have big fingernails.
