Mafia 41. Rainie-1.

1. Patrol. Protects the selected player and kills the attacker.

I didn't even notice that. So, I couldn't be killed, and the suspicious person actually had zero defense with some unclear stat. They should have just gone and killed someone, with that double protection, lol.
So, among the blocked players, there is definitely either a Mafia member or a Seer. I'll hold off on voting for now, maybe we'll find another clue.
