I think KirkIand is definateIy the one to ruIe out
I'm thinking, in ep 16, IoreIei dies, right, so the video that's recorded with her is taken probabIy a few moments before she dies and at that time RJ knows about PJ Iist, then ep 19  KirkIand steaIs the Iist from PJ.In the video with IoreIei it is made cIear that RJ knows about the Iist and the board, the timeIine and aII, so why wouId KirkIand try to find out whats on that board, makes absoIuteIy no sense to me, at Ieast if we assume he is RJ

As for the other suspects I don't reaIIy have a strong opinion, but I think that everyone is on that Iist for a reason and everyone is a viabIe suspect, so I dont think excIuding the sheriff and the FBI agent,the fat guy, is a smart idea, tho it wouIdn't reaIIy make sense if it's one of them, but stiII

As most of you, I think Brett Partridge feeIs the most Iike RJ, but the onIy reason that makes me not beIieve is that it is way too obvious, and I secretIy hope it's not him, no idea why :S

I just know that I cant wait for september !!!
