Prosciutto

Antagonist from Part V: Vento Aureo. He belongs to the defected assassination faction of the Italian mafia gang, Passione, called La Squadra Di Esecuzion.

About
Prosciutto and fellow member of La Squadra, Pesci, are sent after Blono Buccellati and his gang to capture Trish Una in order to find out The Boss's identity. Although they manage to catch up to the gang at the train heading to Florence, they soon loose sight of them due to a newly found turtle's stand. In order to flush the gang out, Prosciutto decides to use his stand,The Grateful Dead, to age everyone on board the train. This leads Guido Mista to come out from hiding to try and stop the aging. After Mista has a confrontation with Pesci, Prosciutto is able to take down Mista from behind and use his own gun to shoot him in the head, supposedly killing him. Soon after, Prosciutto and Pesci are able to find the turtle holding the gang, forcing Buccellati to come out and fight. After a short scuffle, Buccellati manages to use his Sticky Fingers to make Prosciutto fall out of the train. Out of sheer luck, Prosciutto manages to get himself caught in the train's wheels and barely survive with fatal wounds. Knowing he would die, he determined that he would use his stand and hold out long enough to give Pesci the chance to kill the gang, and steal Trish away. When Pesci died at the hands of Buccellati, Prosciutto lost his will to live and soon died along with him.
