[3] From September 1944, she was a collaborator of the partisan Luigi Canali (known as the captain Neri) and, with him, had an important role in the arrest and the execution of Benito Mussolini and Clara Petacci.

On 6 January 1945 she was arrested with Canali in Lezzeno by the members of the XI Black Brigade "Cesare Rodini" and tortured for 23 days.

[1] After this period, she was transferred to SS headquarters in Monza by a Gestapo officer, Captain Vernig, who pitied her condition and was impressed by her bravery.

[1] 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.
