I don't get why you guys are so stuck in the 'Brett Partridge is Red John" thing.Let's clear some things out.First of all, for those who say that RJ's voice is the same as Brett Partridge's, I answer:You couldn't be more wrong.For two main reasons:First, RJ's voice is Simon Baker's voice (NOT Patrick Jane's don't confuse).Here's the proof:http://www.youtube.com/watch?v=OUikVzxQuuY
Again, I dont state Patrick Jane is Red John what I'm sayin is that Simon Baker's voice (actor) with sufficient editing, is the voice of RJ.
Reason number two:Do you REALLY believe that RJ would present to Jane with his own voice?That would be stupid of him.It's a really high risk and Red John isn't dumb.
Additionally, Brett Partridge is the perfect Red John.That's true.But it's also too obvious.And Bruno Heller hates something like that.The plot of The Mentalist as a TV series itself excludes that RJ would be obvious.The surprise and the excitement, the  contingency, the given clues to the people so they will come up with their own theories, to discuss them is the MAGIC that this show has to offer.Dont ruin this.You just want Brett Partridge to be RJ so bad that you find any possible mean to explain this theory.I dont say that Brett Partridge isn't RJ.I just believe in the possibility that Heller didnt want to put Partridge at the list of suspects.But then we were all about to say : "The list is wrong, B.Partridge is RJ".Heller included Partridge to the list to make people into thinking that the list is correct.Then he gets rid of Partridge at the very next episode.The only thing that makes me hesitate to exclude one and for all Partridge from the suspects is why RJ would ever kill him?What's the motive?And why not kill Lisbon after?For me, Partridge , Kirkland (Bob or Michael) , CBI Ron would be the perfect RJs.On the other hand, I will be very disappointed if RJ turns to be one of the remaining suspects.
