The Brutal Art of True Gore

The Dnepropetrovsk maniacs.
Based the video known as '3 guys 1 hammer' in which a pair of naughty little boys film themselves killing a guy by bashing his face in with a hammer, the cameraman then rams a screwdriver into his head after filming his bleeding face close up, the original kid then gives the victim a final couple of blows to the head before they leave.
Finished video here, Three guys, one afternoon.
