The Washington Criminal History and Your Own Copy
Washington is one of the states that lets anyone look up another person's statewide criminal history: WATCH lets anyone search conviction records by name online, for $12 a search, through the Washington State Patrol. The result is the repository record, what agencies reported to the state, which is wider than one county's court index but can lag it. The search is on the Washington State Patrol site.
Arrest Records Kept Locally in Lacey
The Thurston County Sheriff's Office and the agency that reports for Lacey (filed by the FBI as Lacey Police Department) keep the arrest records in and around Lacey: the report and the booking record of each arrest stay with the agency that made it, separate from the court file and from the state repository.
The FBI's agency list also places these agencies in Thurston County: Evergreen State College (campus police); the State Gambling Commission Enforcement Unit and the State Insurance Commissioner's Special Investigations Unit (state agency); each keeps the records of its own arrests.
Together, the five agencies in Thurston County with all twelve months of 2025 on file reported 5,749 arrests to the FBI that year; how each case ended is in the court file, not in the arresting agency's.
The agencies and their counts, year by year, are in Lacey arrest records.
The Crimes Behind the Records: Lacey in 2025
The agency that reports for Lacey had 130 violent and 1,152 property crimes reported for 2025; each one is a report on file with it, and each arrest that follows is the start of a criminal record.
