About Us

The Office of Police Accountability helps ensure the actions of SPD employees are constitutional and in compliance with federal, state, and local laws by investigating and making recommended findings regarding allegations of misconduct. OPA is a hybrid oversight-agency comprised of both sworn and civilian personnel. The OPA Director and Deputy Director are civilians responsible for carrying out the purpose and mission of OPA including classification of complaints for investigation and making recommended findings to the Chief of Police for all sustained cases. Currently sworn SPD Sergeants conduct the investigations initiated by OPA. Under recent legislation passed by the Seattle City Council and signed into law by the Mayor, OPA will eventually have a combination of both sworn and civilian investigators. In addition, under the new legislation, OPA will have civilian Complaint Navigators, who will be working directly in the community to forward the mission of OPA.

Tonia S. Winchester, Deputy Director

Tonia Winchester has been working within the criminal justice field for more than a decade to bring about reforms to build trust between law enforcement and the community. After years serving as a prosecutor for the cities of Seattle and Wenatchee, where she handled large volumes of misdemeanor cases, Tonia was the Outreach Director for the New Approach Washington campaign that successfully legalized marijuana in Washington State. Her high pressure role included forging alliances and winning endorsements from many groups traditionally seen as hostile to marijuana reform, such as the Washington State Labor Council, AFL-CIO, Children's Alliance, and El Centro de la Raza. Tonia was also called upon to speak across the state advocating for the sensible use of law enforcement resources to focus on violent crime.

Tonia's Persian heritage combined with her professional experiences are the foundation for her passion to ensure constitutional and bias-free policing. Working alongside community members, local leaders, SPD employees, and OPA staff, Tonia has diligently sought to ensure OPA brings accessible, trusted and transparent oversight to the Seattle Police Department. By working to establish classification standards and ensuring transparency into all processes within OPA, she hopes to achieve long-lasting and tangible positive transformation within the Seattle Police Department.

Tonia received her B.A. from the University of Washington and her law degree from Seattle University School of Law. Born and raised in Alaska, to a Persian mother, Tonia has made the Greenlake area her home with her Great Pyrenees dog Sephideh.
