and she, as a blocker, really wasn't very relevant there
If she is a town member, then yes, she looks like a daughter, thanks to these somewhat illogical, but quite obvious slips. And although it would be a bit silly for a maniac to stick the murder weapon in the door and leave, in theory, he should switch to the side of the town. He switched. And then the conspirator killed the daughter.
In the event of a partner's death, the other one goes to avenge the killer that same night (the maniac's original target is lost) and dies with him.
The fact that she was blocked by a witch, in my opinion, is a fact. Besides the sleeping coke dealer, no one else has contact with alchemy, and the witch's moves are no longer visible anywhere else. The mafia has no reason to block the remaining helpless town members at night and kill them that same night. They should spread out the night actions and look for the maniac to make their lives easier.
Perhaps she wasn't a daughter either. I don't know what else she could be. I don't see any zealous fighters in the list of roles.
Evidence.
It may well be a false clue. Usually, the maniac provides false clues, because he is a loner and it is more difficult for him. The mafia has expendable people. What can be considered evidence? Blindness, a severed hand. I don't know.
Do as you wish, but if you don't execute anyone, neither on a flimsy clue nor on an obvious one, then all means are useless.
azniv Azi, in the end, we will get 2 mafia members against 8 town members, it seems...
