Mafia 27. The problem of Bovblob residents

in-game mail message about unicorns, because it's at the end. And about the bear and the wolf... I think it's a clue, maybe a planted one. Also, there's no signature. Sky, is this a note or not?
If I didn't suspect acrobats in both murders, I would have thought that the note hinted at a magician with a saw.
