John Abruzzi is a Chicago mobster incarcerated at Fox River State Penitentiary and as such he holds a great deal of power inside the prison walls. He has a deal with guard captain Brad Bellick which gives him control of Prison Industries, so he determines who gets the cushy jobs.Not surprisingly, Abruzzi is inclined to use violence as a way to get what he wants, but he's also astute enough to recognize when it's not going to get him anywhere.Because he has something that Michael Scofield needs to execute this plan, he is able to worm his way into becoming one of the Fox River Eight.Background: The testimony of witness Otto Fibonacci was key in securing Abruzzi's conviction for killing two men and earning a sentence of 120 years. Although Fibonacci is in witness protection, Abruzzi hopes to find him and exact his revenge and this desire blinds him to almost everything else.His wife is Sylvia and his children are Nicole and John Jr.
