My theory:

Mrs D buried Alison to protect the person who "killed" her. But: if it was a mentally unstable person, then he or she wouldn't get punished for murder, because you cannot imprison or charge mentally unstable persons. Thus, if it was any freaky twin from Radley, there would not be any reason to have to protect this person, because he/she would get sent away to Radley.

So, the person who "killed" Ali, doesn't it have to be someone who IS mentally stable? Someone like Jason for example.
