The watchman, 68, fired five shots with a pistol for which he has a license, source said. The villa is in the countryside near Bazzano. He fired the shots after hearing noise outside the villa. The dead man was said to be aged between 20 and 25. He was without documents and is still being identified. The man was believed to have been accompanied by others who helped him break into a building.
