Mafia 29. Witch Hunt

Well, as always, I'll go with the clues. La Commedia --> Commedia dell'Arte, "comedy of masks." Aves not only has a mask in his avatar but also a phrase in his signature saying that a person reveals himself precisely by putting on a mask.

But since, according to all my clues, the city doesn't immediately execute but patiently waits for a couple more innocents to be killed, I don't even hope for understanding.
