The name Red John goes by is Ryan parks he owns the jet Stiles flies around on undetected sounds like something Red John would have used to fly to Mexico and kill Jared Renfrew so I can't say who will be attached to that name but it's important remember when Patrick got L Martins out of jail they went to a cabin she said was her sisters but they look up the records and say that someone has been paying the taxes on it but they never say the name I bet it's the same person who owns the jet.  Just something new after listening to some of the obvious theories.
