A helicopter has crashed in north-central Italy killing three people including the head of Italy’s Rovagnati salami and prosciutto maker. The mayor of Biassono, where Rovagnati is based, says among those killed was Lorenzo Rovagnati, chief executive of his family’s company. In a social media post, Casiraghi said the accident occurred in Castelguelfo di Noceto, near Parma. Rovagnati’s best-known brand is the Gran Biscotto cooked prosciutto, though it also makes salamis, mortadellas and other types of processed meats.
