While the possibility of bussing Missigno is there, I say that Human is more or less cleared because:
He lynched the captain, the role that was controlling my night checks. The mafia hadn't gotten the cop(me) yet. Obviously, they wouldn't risk losing someone that basically saved them from nightchecks and buyed them time.
Just my two cents.
And @Croag; Whoever is sending this messages is obviously lying about their role. Which is to say, that they have claimed something else. AKA, there is no godfather in this game. It was all the "Messanger's" doing.
