SeaTac is home to Seattle-Tacoma International Airport, one of the busiest airports in the western United States. The presence of the airport affects the mix of law enforcement activity in the area, with federal agencies such as the TSA and Port of Seattle Police also active within the city. Federal criminal cases are handled separately through the federal court system, not through King County or Washington State courts.

How to Search SeaTac Criminal Records Online

You can search by name, case number, or date range. Results show case type, charge information, filing date, and current status.
For felony-level cases, the KC-Clerk portal provides more complete Superior Court data. If you know the charge was a felony, start with KC-Clerk for the most thorough results. Both tools are free.
If online searches return no results, consider these possibilities. The case may be sealed. It may involve a juvenile. It may predate electronic records. Or it may be a federal case, which is outside the state court system entirely. A written public disclosure request to the relevant clerk is the next step for state court records. Contact information for each clerk is on the court's website. Requests are typically answered within a few business days for standard documents.
Cases involving activity at Seattle-Tacoma International Airport may be handled by federal agencies and federal courts. These records are not in the Washington state court system and require a separate search through federal PACER.
Washington State Patrol Criminal History Records
The Washington State Patrol (WSP) maintains the statewide criminal history repository. When the King County Sheriff or SeaTac-area law enforcement makes an arrest, fingerprints and arrest data are submitted to WSP. That information is added to the state's criminal history system, which covers arrests and convictions reported by law enforcement agencies across Washington.
Name-based criminal history checks through WSP's WATCH system cost $11 per online request at wsp.wa.gov/crime/criminal-history. WATCH results show convictions and arrests on file with the state. This tool gives a broader picture of criminal history but lacks the case-level detail found in court portals. It is a useful supplement to a court records search, not a replacement.
WATCH is a name-based tool. Results may include records for multiple individuals with the same name. Always confirm details with the relevant court clerk before drawing conclusions from a name-based search result alone.
Washington Public Records Law and SeaTac Cases
Washington's Public Records Act at RCW 42.56 gives the public broad access to government records. Most adult criminal court records are open under this law, including case filings, charging documents, judgments, and sentencing orders. Agencies must respond to records requests promptly and can only withhold records that fall under a specific statutory exemption.
The Criminal Records Privacy Act at RCW 10.97 limits how criminal history information can be shared. Arrest records that did not lead to charges or conviction may be restricted from public disclosure in certain situations. Agencies responding to records requests involving criminal history data must comply with RCW 10.97. This law prevents non-conviction records from being used in ways that fall outside what is permitted.
Juvenile court records in Washington are sealed under RCW 13.50. Public portals and standard records requests will not return results for juvenile cases. Only authorized parties can access these records, and doing so requires direct contact with the court with proper authorization. If you are searching for a case involving a minor, you will not find it through public tools.
Washington criminal offense classifications are in RCW 9A. Knowing whether a charge was a class A felony, gross misdemeanor, or misdemeanor tells you which court handled the case. Felonies go to King County Superior Court. Gross misdemeanors and misdemeanors go to District or Municipal Court. That tells you which records system holds the file you are looking for.
