Мафия 2. The City of Lost Heaven

Well, I won't fight anymore)) if people want to make the same mistake again, then good luck to them^^ (maybe next time they'll think that long hair isn't just on me))

No, Neira, the whole problem is that you're the only one with both long hair and a gun.

By the way, I had this thought:

a long hair and a gun were found near the victim's body.

It's just as likely that a maniac fought with Ulric (because no one argues with that), and the gun might indicate who the killer was, i.e., a maniac or a mobster. A double interpretation of the clue. If Neira hadn't given herself away earlier by trying to protect Zubr (whose connection to the mafia I consider quite plausible), I would still have serious doubts.

Another argument is that the maniac hasn't killed anyone for the second time in a row. It's possible that it was Am. Or he's still among us, but his actions have been blocked twice by that bitch, or by the good doctor Aibolit. That's it.
