A Message from District Attorney Tierney

As the District Attorney, it is my job to prosecute those who break local and state laws, on behalf of the People of Suffolk County. I was elected to seek the truth, deter crime, promote the common good, and to protect the safety and quality of life of all Suffolk County residents.

 

Working with our government, law enforcement, and community partners, my office convicts the guilty, protects the innocent, and supports victims.

 

These important duties of the Suffolk County District Attorney’s Office are fulfilled each day through the efforts of over 500 employees, including Assistant District Attorneys and investigators, who are dedicated to upholding the ethical Rules of Professional Conduct and pursuing fair and equal justice for all.
