There's nothing in the writeup about a silencer, and seeing how thorough it is, I don't think there is anyone silenced today.
@BKB I don't think it's a SK cos on the first night didn't the individual roleblock someone?
It could be Themer trying to get on the back of someone he knows is town so that in the event he goes down there is suspicion on that guy. Normally mafia try not to associate with each other at all. I would say Mani is the most suspicious at the moment though.
wrt Mark I don't think there's really anything suspicious about him. I think his lynch was an honest mistake by not reading the post before him.

And also, to back up one of Abhas' points, it's possible that the silencer was the one who carried out the kill. Something about how he had done his job the previous night but had a bigger job tonight? There aren't many non-lethal mafia roles.
