Romualdo Bucciero was an Italian immigrant to Britain and the brother of Adalfredo and Gomberto Bucciero. In 1919, he and Gomberto witnessed the murder of their brother Adalfredo by traumatized World War I veteran Daniel Owen in front of his own restaurant, and they demanded that Owen be murdered as retribution. Tommy Shelby shot Owen with a sheep brain-filled bullet in front of them to make it appear as if he had shot Owen, but Owen secretly survived, while Shelby appeased the Italians.
