I don't think so. But there was the Night of Terror, judging by the newspaper's name. Or can he even kill during that night? Then that explains everything, a little.

Yes, it's especially unclear with Neira. The only role that kills the attacker is Frank, but he's also dead now. The Margrave would have died too.
