Can't say that I was "involved" in it... but can say that I experienced it through those that I considered my friends at one time, who did. Strange story....moved into house with girlfriend, it was an old house, which needed serious cleaning. Found poster of flasher, and trashed it. Came back and was found on kitchen table. Tore it up and trashed it, with special trip to garbage can to make sure it was out of the house. It came back. We were scared by then, and then comes this girl who said she was a white whitch, and she will get rid of it for us. Instructions were to hold a scence. Candle in middle of floor and we were to gather around indian squatting. She did her mumbo jumbo and then the room, even though it had the candle and the lights on, grew dark, and the air got heavy, it stank with a putrid odor as the light from the lightbulb and candle got dimmer. I said "Jesus" and a spark of light shot through the window to the candle, and the depressive, dark atmosphere left. The white witch was furious. I didn't care. The poster was burned in the trash barrel and that was the last we saw of it.
