Not a theory, only a doubt. How could RJ get to the same 7 suspects in only few hours, while Jane took some weeks to do the same?

Obviously RJ didn´t find out by the information Kirkland got because he had already recorded the cd. And Jane wouldn´t be so stupied to let the correct information into the CBI.

So, I can presume that the false information here is that Jane shook RJ´s hand before. This way, RJ could have enought time to think very well about those 7 options before Lorelai planted this false clue.

Maybe RJ really is some of those 7 suspects, but he wanted Jane to get to those names. I just don´t know why.
