Biography
Assassination of Galeazzo Maria Sforza
On December 26, 1476, Olgiati, along with his fellow assassins Giovanni Andrea Lampugnani, Lampugnani's servant Franzone, and Carlo Visconti, attended the Mass at Santo Stefano. After Lampugnani delivered the first blow to Sforza after the latter's arrival, the others followed him. All the assassins except for Lampugnani managed to escape, only to be caught and executed within one week. One of Galeazzo's guards managed to catch and kill Giovanni despite Giovanni Auditore shouting not to kill him so that he could interrogate him. This failed, and the guard snapped Lampugnani's neck and went over to mourn Galeazzo. Giovanni then want over to Lampugnani's body to search it but found nothing but a bag of coins.
