come on guys...thomas mcallister, really ? i guy whose only jurisdiction is in Napa or whereabout the countryside ? i definitely don't see him being red john, no matter how spooky he is, and showing at the end, he is not actually afraid of heights.
i still think it's kristina frye, controlling a group of suspects, one being red john the killer, another being red john the informer, another being red john who has all the funds, etc etc....
