According to Bruno, the list is legit.  But there's something that doesn't make sense about the seven suspects. Jane is someone who has an eye out for everything. He catches things that others don't see and always find a loop hole in a case which leads him to identify the murderer.  What I can't wrap my head around is, all the clues that have been dropped throughout the seasons, how did he come up with this list?  

In the episode where the Sheriff turned out to be working for RJ and says that him and his dad were friends which indicates he's somewhat older.  How does that fit Partridge for example?

According to evidence, RJ may have been part of visualize, and trying to get the age right, it rules out Gales and Stiles.

Something isn't adding up and I'm not sure what it is. But these clues, are things that Jane would not be that dumb to make a mistake in judgment of the suspects.  He's far too smart to make a mistake or oversee a detail.  Especially with this RJ, he would we would be 1000% (yes thousand) sure before coming up with his final list.  
 
So is Bruno stringing us along?  Are there other suspects? Is the list legit? I'd hate to think that the writers fumbled and were not cautious with how it all add up.  Also would hate to think that some clues were false to throw us off track. That would suck.

If I had to guess, my bet would be partridge but because of the sheriff's dad and RJ who were friends, I don't think so because the age doesn't fit.

I love how it's really making us think!
