In what sounds like a Spanish speaking country (or the US of A), a young girl was filmed on a vertical video repeatedly bashing her head against a wall. The wall got sprayed with quite a bit of blood from all the bashing.
Eventually, some passers-by got the girl to stop smashing her face, but by that time her face was a bloody mess.
I have no idea what possessed the girl to do that. High on drugs, perhaps?
Apparently this happened in Cancun, Mexico.
