Carlo Visconti

Carlo Visconti was a government secretary in Milan's Council of Justice, an assassin of Galeazzo Maria Sforza and a member of the Knights Templar.

On December 26, 1476, Visconti and his fellow assassins Giovanni Andrea Lampugnani, Lampugnani's servant Franzone and Gerolamo Olgiati attended Mass at the Santo Stefano. After Lampugnani had delivered the first blow to Sforza after the latter's arrival, the other assassins followed him. Visconti and Olgiati managed to escape, only to be caught and executed within the next week.
