Retired Hazelton police lieutenant Mark D. Koch, lawyer Everett A. Gillison, Pittsburgh resident Linda P. Rosenberg and Erie County resident Theodore W. Johnson were confirmed Wednesday as new members of the state Board of Probation and Parole. 

Pennsylvania Governor Tom Wolf nominated the four based on their education and previous experience.

State Probation and Parole Chairman Leo L. Dunn said all four members are experienced in the areas of public safety, victim issues and offender management.
