hey everyone,
i'm not here to tell you or prove my point about any of those suspects.i was thinking about this whole Red John thing and this idea just came to my head.i guess you people remember (Rosalind Harker) a blind woman and former lover of Red John.Jane could use her help to catch Red John.she has already helped him once to confirm that the man Jane had killed was not Red John.So Jane could simply make Rosalind hear the voices of those 3 suspects and if she knows Red John that well she'll definitely identify his voice.All this time Red John was one step ahead Jane.But with this Jane could easily catch that monstrous serial killer.
