Seattle will host a question and answer forum with the three finalists for chief of police on Thursday.

The forum, which will broadcast at 6 p.m. on the Seattle Channel and air live on the Seattle Channel’s YouTube, will be the last step in a months-long process to identify a permanent chief before Mayor Bruce Harrell nominates one of the candidates to be confirmed by the City Council.

Harrell announced the three finalists — including two internal candidates and one from the Tucson Police Department — last week in a release. They were selected by Harrell’s search committee out of 15 candidates provided by a private hiring firm.

Adrian Diaz 

Diaz, who was originally hired in 1997, was promoted to deputy chief in 2020, after serving as an assistant chief in charge of the department’s Collaborative Policing Bureau. He assumed the interim position in 2020.

He has also worked in the department’s patrol and investigations units, among other assignments. 

According to the mayor’s office, Diaz has completed training from the FBI’s National Executive Institute, the Major Cities Chiefs Association’s Police Executive Leadership Institute, the Cascade Executive Program and the Senior Management Institute of Policing.
