UPDATED 11:58 am 10/30/09 - Here is more complete video of the shooting. It actually shows the man committing the murder:
Here is security tape video of a Mafia murder in Naples, Italy taking place. In the video, you see a man standing to the left smoking, and out of nowhere comes a gunman who shoots the victim in the neck and walks away. You don't actually see the shot to the neck because it all happens so fast, but suddenly the victim is on the ground and the gunman is walking away. Police are still looking for the killer, whom they believe is connected to the mafia.
