I remember a scene of a film I saw in the 1990s- early 2000. I know i was probably was too young to watch that.
So the scene is in a bright room with jail-bars in the back. A man was there, a very strange man, with long and dirty dark hair. I don't know how he got a gun but he shot himself in the mouth. There was other people in the room talking about the strange man.
I seem to remember something about a golden tooth, a car on fire with one or more people inside and a girl with strange drawing.
