Giuseppina was born in 1923 in Abbiategrasso, in the Province of Milan, but lived and worked as laborer in Baggio, a suburb of Milan. In 1943 she started her activity of partisan courier, using the pseudonym "Gianna". On 6 January 1945 she was arrested with Luigi Canali in Lezzeno by the members of the XI Black Brigade "Cesare Rodini" and tortured for 23 days. After this period she was transferred to the SS headquarter in Monza by the initiative of a Gestapo officer, the captain Vernig, moved to pity for her conditions and impressed for her bravery. On March 12 she was released. Refusing an escape route to Switzerland, Gianna continued participating to the partisan struggle in northern Lombardy. She and Neri were present during the arrest of Benito Mussolini and Clara Petacci, on 27 April near Dongo; and to their execution, the day after, in Giulino. Suspected of betrayal, to have revealed some names of partisans during her detention, she was arrested in Baggio on April 29 and detained until May 9, inquired by Pietro Vergani, regional commander of the Garibaldi Brigades and PCI member. During the detention she became aware of the death of Luigi Canali, executed by a partisan tribunal. At the end of May 1945 she come in Milan with Alice Canali, the sister of Luigi, to know more about his death. Despite threats, Gianna continues to ask questions threatening to reveal what she learned. In June she also met Ferruccio Lanfranchi, editor of the Corriere d'Informazione, that is investigating on the death of Mussolini. Feeling abandoned by the comrades of her party, Gianna disappeared on 23 June 1945, in the day of her 22nd birthday. Is presumed she was killed and his body thrown into the Lake of Como near Cernobbio. Her death, the one of Neri and other partisans in the late spring of 1945, represents an unresolved mystery of the Italian resistance history. In 1957 Dante Gorreri, PCI secretary of Como, and Pietro Vergani, were charged for the murder as instigators; Dionisio Gambaruto and Maurizio Bernasconi as executors. The trial, held in Padua, did not end for a series of procedural impediments.
