Of the remaining people Byakuya and Chiaki, where are your suspicions?

If it sounds like I am a contestant on a blind date television programme (In the Kingdom of Novoselic, our programming is reduced to cheesy soap operas), I'm trying to get as much information as possible in the event that if our cop survives this lynch and they're killed in the night (say a doctor got roleblocked or something): we at least have their final summaries and thoughts from a confirmed Town, and a power role at that.
