Mercer Island Arrest Records Search
Mercer Island arrest records are public under Washington's Public Records Act, RCW 42.56, and the city manages requests through two separate channels: the City Attorney's Office for general public records and the Police Records Unit for incident reports and police documents. Both offices use the city's NextRequest online portal, where you can submit requests and receive updates electronically. The city is in King County, and people taken into custody are transported to the King County Jail.
Mercer Island Overview
Mercer Island Police Records Unit
The Mercer Island Police Records Unit handles requests for incident reports, arrest records, collision reports, and other police documents. The unit is at 9611 SE 36th St, Mercer Island WA 98040. Phone is 206-275-7610, and the email is mi-records@mercergov.org. Fax is 206-275-7941. Office hours are Monday through Thursday, 9:00 a.m. to 4:00 p.m. The unit is closed on Fridays.
The Mercer Island Police Records page walks through what types of records are available, how to submit a request, and what fees apply. Fees are set under RCW 10.97.100, RCW 42.56.070(7-8), and RCW 42.56.120. The city can ask for a deposit of up to 50% of the estimated cost for large requests before work begins.
Payment at the police records unit is accepted in cash, check, or credit and debit card. For traffic accident reports specifically, Mercer Island uses BuyCrash.com rather than its own internal system. To use BuyCrash, you will need the case report number and the date of the incident. The police records staff can confirm whether a report is available before you access the third-party site.

Public Records Officer and NextRequest Portal
General public records requests, meaning records that do not originate from the police or fire department, go to the City Attorney's Office. The Public Records Officer is a Senior Paralegal named Mary Swan. Her contact is 9611 SE 36th Street, Mercer Island WA 98040, phone 206-275-7651, and email prr@mercerisland.gov. Police and fire records have a separate Public Records Officer at the police department level.
The Mercer Island Public Records page explains the city's public records policies, which fall under RCW 42.56 and Chapter 2.14 of the Mercer Island City Code. Both sets of rules apply to how the city handles requests, exemptions, and appeals.
The city uses NextRequest as its records management portal. The Mercer Island Records Portal lets you create an account, submit a request, and track its progress online. You will receive email notifications as the city works through your request and when documents are ready.
Using NextRequest is generally faster than mailing a paper request. The portal also keeps a history of your prior requests, which is useful if you need to follow up or reference past submissions. If you are unsure which office to submit to, the portal will help route your request to the right unit.
King County Jail and Booking Records
People arrested on Mercer Island are taken to the King County Jail after processing. Mercer Island does not operate its own detention facility. Under RCW 70.48.100, the name of the arrested person, the booking date, and the cause of arrest are always public from the moment of booking. You can access these basic details without a formal records request.
For current custody status and release information, VINELink covers King County facilities and is available at no cost. You can sign up for automated notifications tied to a specific person in custody. The service does not require a records request and runs around the clock.
Court records for cases that stem from Mercer Island arrests are handled at the King County District Court or Superior Court depending on the charge level. Misdemeanor matters handled locally may also appear in the city's municipal court records. The Washington Courts case search covers all of these court levels and is free to use. You can search by name, case number, or date without submitting a records request.
Statewide Background Checks and Criminal History
For a statewide criminal history, the Washington State Patrol's WATCH system costs $11 for a name-based search and returns results online. WATCH covers convictions statewide, not just King County. It is the most reliable public-facing tool for checking someone's history in Washington. Mercer Island arrest records only cover incidents within city limits, so WATCH gives a more complete picture.
Under RCW 10.97.050, conviction records are public and can be shared. Records tied to cases that were dismissed or not pursued are treated differently. You can inspect those records but copying is more restricted. This applies whether you are requesting from the city or from the county.
Keep in mind that an arrest record is not a conviction record. The two documents mean very different things. An arrest shows that law enforcement took someone into custody. A conviction means a court found or accepted a guilty verdict. Not every arrest leads to charges, and not every charge leads to a conviction.
Note: Arrest records document a booking event. They do not indicate guilt or a conviction in court.
