Some things to think about:

Bob Kirkland's team broke into Patrick Jane's room to get info. - I assume this is how Red John got the list of suspects that Jane had narrowed it down to.

This happened three episodes after Lorelai Martin was found dead. Therefore the video that shows up with Lorelai naming the suspects means that Lorelai must still be alive (or she has a twin) - Remember Patrick says Red John is not phychic, he just uses tricks!

Patrick knew that someone may have been breaking into that room (he broke the match in the door to prove it) - Therefore is it possible that he has fed Red John false information?

Red John may be more than one person, or at least a few of the suspects on that list are working for him.
