Seattle Police Chief Shon Barnes resigned amid criticism of the city’s communications after a festival shooting killed three people. Officers responded quickly at the scene, but officials did not provide a substantive public update for nearly five hours and the mayor retracted an inaccurate custody statement. Mayor Katie Wilson appointed Deputy Chief Andre Sayles as interim chief after Barnes resigned Thursday.

Three people, including one suspected shooter, were killed and four people, including a two-year-old child, were wounded at the Bite of Seattle festival. Court records said at least one officer saw a 15-year-old suspect firing into the crowd and persuaded him to surrender. Barnes was outside Seattle at a law-enforcement conference when the shooting occurred.

Police are searching for at least one additional person believed to have fired during the incident. After an initial social-media post, almost five hours passed before police gave the public another substantive update. Several Black community organizations and at least six City Council members argued that Barnes should remain in office.

The city did not use its emergency alert system, and Wilson withdrew an earlier statement that two people were in custody. The city has had four police chiefs in less than three years and is entering another major festival weekend.

The evidentiary boundary at publication is specific: The shooting investigation is active, the remaining suspect has not been identified publicly and the resignation does not by itself establish individual responsibility for every communication failure. The current account therefore distinguishes completed events from announced, proposed or still-contested steps. Statements by governments, companies, litigants and advocacy organizations establish what those parties said; they are not treated as independent proof of every underlying assertion. Numerical values describe the source period and category identified in the reporting and may be revised by the responsible institution.

The next public records expected to update this account are charging decisions and the search for the remaining shooter and the mayor’s review of emergency alerts and the process for selecting a permanent chief. Until those records appear, the dates, totals, procedural posture and attributed descriptions above are the latest checked account for the July 31 edition. A later filing, official release, verified field report or corrected dataset could change a total or timetable without erasing the documented sequence at this cutoff.
