Mafia 14. Overcrowded trolleybus.

Okay, I'm completely lost here...
They tried to kill the Decontaminator, but did the Investigator trigger? Who killed him? The Mafia? The Madman?
Was the Lizard killed by the Military?
Was the Hermit killed by the Mafia or the Madman?

Cash was checked by the Nonconformist.
I was checked too... but how? Damn... I thought the Alcoholic was already dead...
Damn, my head is spinning...

Mold is the Madman... definitely...

Damn...

The Alcoholic is an elderly man with a bottle of vodka in his hand, and he's only capable of repeating what everyone else says.
ND: Repeats the ND**
Character: Bad

**Can only copy the ND from one person.

But it seems like yesterday and today, the Alcoholic was repeating the Nonconformist's ND... but that's impossible... so I must be misinterpreting the actions somehow...

Ah... wait... how many actions does the Mafia have?
Can the Mafia kill and investigate a character's role simultaneously?

It's just unclear... it says:

• The Mafia has one opportunity to commit a murder per night.

But how many actions can the Mafia perform in one night?

Added after 2 minutes
If they have two actions, then the Mafia is clearly looking for the Military... and the Beggar...

I already received a clue about Kyle from Soundspark pointing to me; it's unlikely that such clues will be repeated.

And there's some weak connection between the red rag and Kyle's clothing... it's too vague and ambiguous.
