Could it be that the maniac is Vegtam? Like, first he kills Cash, and then someone kills him? (Nah, that doesn't happen, probably).
1. Blocks/Protects the cop.
2. The Jester learns the status.
3. Kills the spy.
4. The maniac kills.
6. The mafia kills.
7. The doctor heals.
So, it's possible, but then we got really lucky.
