Captain Bellick passed the Correctional Officer Exam the autumn after he graduated high school and has been at Fox River Penitentiary ever since. In that time, he has slowly and steadily climbed up the C.O. ranks.
Three years ago, despite several claims of inmate abuse (none of which could ever be corroborated), Bellick was promoted to the position of captain, the highest rank a C.O. can earn. Today, his duties include: aiding in the transportation of death row inmates to the electric chair, supervising Fox River's prison industries program and overseeing the day-to-day operations of all the inmates in general population.
Bellick is what's known as a C.O.'s C.O., and operates by two simple rules: There is no such thing as a “good convict,” and the main purpose of a prison is punishment, not rehabilitation.
