Mafia 44. Time of Troubles

This seems to indicate a werewolf. But I don't understand whose image he took on. Who among us can strangle someone?

someone who is unarmed. Never mind, it's not important anymore.

Also, the angel has a spear, but I think the Pole killed with a polearm. Then everything fits together.

an angel wouldn't kill his own. But the city archer also has a spear.
I understand that yesterday there was no murder by Lithuanians and Ney was blocked, but today there is a murder and it could be from a possible Crusader.
