I live about 5 minutes' drive from the site where the car was dumped. There is no possibility that someone could drive off there without being severely impaired (and even then, I highly doubt). It is obvious just looking at the site that you would have to premeditate the crash. I also know one of the detectives that arrested them, and he told me that the old man told him outright that he was disgraced by his daughters and did what was right (I can't remember the exact wording). So I don't even see how appeal is possible.
