Which Agency Holds a Report from SeaTac
A crime, incident or collision report belongs to the agency whose officer wrote it, and that agency releases it, not the court, the jail or the prosecutor.
Inside SeaTac that is the agency that reports to the FBI for the city (filed by the FBI as Seatac Police Department); outside it, the King County Sheriff's Office.
The FBI's list also carries the University of Washington (campus police) and the Port of Seattle (other agency), each with a records office of its own.
The Milton Police Department is listed by the FBI across two counties including King County, so its arrests are not broken out for King County here.
