District Attorney John C. Tunney is the elected prosecutor and there are six assistant district attorneys, two of whom work as part time prosecutors.In addition, the office employs an investigator, two paralegals and five clerical employees.

There are two specialized “bureaus” in the District Attorney’s Office.The first is the DWI prosecution bureau and the second is a specialized domestic violence bureau.

In addition to prosecuting crimes committed in Steuben County, the District Attorney’s Office conducts investigations,typically with the assistance of police agencies, in order to determine whether any criminal prosecution is warranted.The office also processes appeals generated by convictions obtained by plea or by trial.Those appeals take representatives of the office into the New York State appellate system as well as into the Federal Court system.

Steuben County contains approximately 1400 square miles and there are more than 50 local criminal courts in which assistant district attorneys appear.In addition, there are three county level superior court judges in the County each of whom has a substantial felony trial calendar.Consequently, the staff of the office is constantly busy covering the various courts which handle criminal cases.

A vital function of the District Attorney’s Office is to educate police officers and, to some extent, the public regarding issues which arise.For instance, prosecutors regularly participate in training sessions for police officers who work for local police agencies.Additionally, individual police officer training is conducted by members of the office staff.

Mr. Tunney and several of the assistant district attorneys often make presentations to groups of citizens concerning crime-related issues.Presentations to students regarding the dangers of drinking and driving and presentations to senior citizens regarding economic crimes and risk factors are examples of the “outreach” program which the office conducts.

The size of Steuben County as well as the diverse nature of its population which includes both a large rural component and a significant urban population combine to create a wide spectrum of crime and crime-related issues for the District Attorney's Office.The dedicated people who work in the office are committed to helping provide substantial justice for the citizens of Steuben County.
