How Do I File a Complaint?

You may file a complaint in person, by phone, online, or by mail. A form is available at each King County Sheriff’s Office (KCSO) location and on our web site. If you live in one of our contract cities, you may also submit your complaint to the city police chief, a supervisor, or a city official.

Emailed complaints should be sent to our Internal Investigations Unit at iiu.sheriff@kingcounty.gov. or by phone at (206) 296-4200.

Who Will Investigate My Complaint?

A supervisor or an investigator assigned by the Internal Investigations Unit will investigate your complaint. You will be given the supervisor’s or investigator’s name and phone number. You can call this person if you have questions or concerns.

What Happens After I File a Complaint?

The person investigating your complaint may ask you to give a written statement in person or by telephone. With your permission, the statement
may be recorded. You may be asked if you know the name of the employee(s) involved. You may also be asked: 

• To describe what happened; 
• To provide the names of potential witnesses; 
• To allow us to photograph any injuries or property damage; and 
• To consent to the release of medical records that are associated with your complaint.

How Long Will the Investigation Take?

We try to complete every investigation within thirty business days of receiving the complaint. If we cannot do so, we will notify you.

How Will I Learn the Results?

When the investigation is complete, we will send a letter to you that explains the results. We also notify the accused employee of the outcome.

If your complaint is sustained by factual evidence, the Sheriff’s Office may discipline the employee or employees. If you are not satisfied with the Sheriff’s Office investigation, you can contact the King County Ombudsman’s Office.
