I'm suspicious of Yukari, and Shinjaro the most. They are both for a No Lynch, and in all the past games I've played Mafia loves either a band wagon jump on for a easy kill, or a No Lynch situation. The No Lynch to me screams Mafia as it puts the townies in a feeling of safety yet puts them in the most danger as mafia gets a free shot on them with 0 threat on them. I don't know if it is a rookie mistake, or a vet move yet, but at the moment my vote is leaning towards Yukari at the moment. Just waiting to see more evidence on my thoughts though.
