The City of SeaTac has selected Marcus Williams as its next police chief, replacing former Chief Troy Smithmeyer who resigned in January. Williams, a 35-year veteran of law enforcement, was chosen following a competitive recruitment process conducted in partnership with the King County Sheriff's Office.

Why it matters

The selection of a new police chief is a critical decision for any city, as the police department plays a vital role in maintaining public safety and community trust. Williams' extensive experience in law enforcement, including serving as chief in other cities, makes him well-qualified to lead the SeaTac Police Department.

The details

Williams will command the SeaTac Police Department, which is managed by the King County Sheriff's Office (KCSO). He began his law enforcement career in 1991 with KCSO after serving in the U.S. Navy. Over the course of his career, he has worked in multiple South King County cities, including Federal Way, Burien, Covington, Maple Valley, Newcastle and SeaTac, serving in patrol, investigative and command roles. Most recently, Williams served as chief of the Sound Transit Police before returning to the Sheriff's Criminal Investigations Division.

  • Williams is expected to transition into the role by the end of April 2026.
  • The position became open after the resignation of Chief Troy Smithmeyer in January 2026.
