Mafia 80. Chronicles in Plasticine.

I'm not saying my hypothesis is definitely correct – that's what a hypothesis is for. More precisely, the part about the Mafia identifying the Serial Killer seems very likely to be true, but the notes might be completely wrong, even the opposite of what they seem. In principle, the truthfulness of the Hacker's note can be verified like this: if it's true, then the Hacker should use their ultimate ability tonight. And everyone else should write a note with some nonsense, and we'll see if they appear or not. The Serial Killer's note cannot be trusted; we can only speculate.
It's already evening, but there's really no one to execute... I'm not sure about Ment at all as the Serial Killer. Nor am I sure about Vesper as Mafia. I don't think we should rely on my hypothesis until we're sure the Hacker's note is true. Nothing is clear about Gur, as always. Of my clues, only one is more or less normal as evidence that he's the Serial Killer, and the second (with the date the clan was founded) doesn't hold up. I think he's more likely to be Mafia than the Serial Killer. At least, I believe in his being Mafia more than anyone else's. Plus, even if he's innocent, he's less useful than anyone else. Therefore, execute Gur.
