Мафия 17. Blood Omen.

One thing doesn't preclude the other. First, a couple came to Cash. Then, one of the lovers was killed.
My point is, if everything happened this way, then one of the victims of tonight is the work of a vengeful lover (so we need to be careful when examining the evidence, as there is a high probability of implicating a citizen). Judging by the descriptions of the deaths, this victim was Lizard – either a serial killer or a member of the mafia. What do you think, Morning, who could Lizard have been?

The description of the couple doesn't say that the widower/widow kills everyone. He only kills the murderer if he finds him. One half of the couple becomes a serial killer only if the other is hanged during the vote, and only Magnus was hanged, and I highly doubt he was one of them. He didn't even deny his guilt. And even if that were the case, a common serial killer wouldn't tear bodies to pieces.

I considered Lizard a zombie from the very first night. The other theories just seem absurd to me.

What makes you so confidently assert that he was exclusively cursed or a vampire?
