Tirinella signalled her order by way of a fleeting glance, indicating that the young Venetian be escorted to the bedchamber. However, out of the corner of his eye, one of the sons had spotted a shadow lurking in the corridor. A moment later the young man pleaded a terrible headache and took his leave. The step-son informed his brothers of what he had seen, and concluded that the family's honour was about to be destroyed under its very roof. Weapons in hand, they marched to their stepmother's chamber. Hearing shouts and cries, Alviso realized he would have to defend his love, and grabbed his sword. Tirinella opened the door and threw herself between her lover and his assailants. The tragedy was played out within a matter of moments: the two lovers were stabbed repeatedly, then dragged to San Giovanni a Carbonara and hurled into the rubbish beneath its walls.
This account of the events was related by Giovanni Aurispa, a Sicilian humanist, to Ferarrese lawyer Niccolò d'Ancona, because, by a singular coincidence, only sixteen months earlier, an event had scandalised the Emilian city, namely the condemning to death of Laura Malatesta (known as Parisina), the wife of Nicolò d'Este, who accused her of having an affair with his son Ugo.
