The second son, Cristoforo, was assassinated by Paolo Bruno, a Corsican, in the prosecution of a love affair with the wife of a Trasteverine fisherman.

The third son, Rocco, spent his time in street adventures, and on one occasion laid his hands on all the plate and portable property that he could carry off from his father's house.

This young ruffian, less than twenty years of age, found a devoted friend in Monsignore Querro, a cousin of the family well placed at court, who assisted him in the burglary of the Cenci palace.

Rocco was killed by Amilcare Orsini, a bastard of the Count of Pitigliano, in a brawl at night.

The young men met, Cenci attended by three armed servants, Orsini by two.
