Following Robust National Search Process, Three Finalists Advance for Next Chief of Seattle Police Department  

Three finalists will participate in a televised candidate question and answer session on September 15 to answer community questions 

Seattle – Today, Mayor Bruce Harrell announced the three finalists for the next permanent Chief of the Seattle Police Department: Interim Seattle Chief of Police Adrian Diaz, Seattle Assistant Chief of Police Eric Greening, and Tucson Assistant Chief of Police Kevin Hall. Read more about the final candidates under consideration below. 

“Our nationwide search process has put community voices at the center to understand what values and priorities Seattle residents want to see in the next police chief,” said Mayor Harrell. “This comprehensive process now brings us three highly qualified candidates, each with the requisite resume, skills, and value set to elevate our One Seattle vision for a city where every resident has a right to feel safe. Our search committee and assessors have advanced candidates with our community’s expectations at the forefront – accountability, community-centered leadership, and innovation. I look forward to meeting with and evaluating these candidates.” 

The City’s Charter sets specific requirements around the hiring of a permanent police chief. To meet core Charter responsibilities, a competitive examination must be held to identify the three finalists from which the mayor will select the next chief. This position also requires City Council confirmation.  

The search process for a permanent chief of police began in April with the hiring of an independent third-party firm to assist in identifying candidates nationwide for the position. Mayor Harrell then created a search committee made up of 14 community leaders, law enforcement experts, victim advocates, and others to determine the candidates that would proceed to the examination phase. 

Community engagement and feedback has been essential to informing the search process. A public survey was made available in seven languages in May to garner feedback from community. Over 1,300 residents responded to the survey, and the results are available here.  

Additionally, seven community conversations were held in July and August to allow the public to make their voices heard in the search process. The community conversations in July were facilitated by the Empower Initiative were focused conversations with faith, business, immigrant, and youth communities. An evaluation report of the conversations from the Empower Initiative are available here

The August community conversations were co-sponsored with equity-focused groups. Summary notes from the August 10 and August 11 meetings are available. 

Fifteen candidates applied for the Chief position. After conducting interviews, the search committee narrowed this group down to a select number who proceeded to the competitive examination. 

On September 6 and September 7, the charter-required competitive examination was administered by four public safety experts. The three finalists were unanimously selected to be advanced to the Mayor’s Office for consideration. 

The candidates will now engage in a series of stakeholder interviews, which will culminate in a candidate question and answer session on the evening of September 15. The event will be televised on the Seattle Channel. Community members can submit questions for the candidates to address here
