Who do you think killed Rosie Larson?
Honestly I really haven't the foggiest idea who it could be yet. I am lean to wards someone in the political game since there doesn't seem to be any real reason to have them in the show unless they are somehow involved. I don't think its Richmond, that would be too easy, but someone on that side of the fence has to have a deep connection to it, or at the least attempted cover up. Again I just don't see why they exist in the story if that isn't the case. Everything else about them is so irrelevant to the plot.
