Mount Vernon, Washington, in Skagit County, has about 35,000 residents (2024 Census Bureau estimate), and its arrests are reported to the FBI by an agency of its own. An arrest in the city leaves the same records whoever makes it: the arresting agency's report, the record of anyone held at the county jail, and, if the Prosecuting Attorney files charges, a case in the Skagit County Superior Court. This guide says who keeps each one, what it costs and who may see it, with the arrest counts the agency reported.
This guide covers who makes arrests, how many arrests, booking and the jail, finding an arrest, copies and common questions.

Who Makes Arrests in Mount Vernon
The FBI lists Mount Vernon with an arrest reporting agency of its own, filed as Mount Vernon Police Department. It reported 1,208 arrests for 2025. A city is listed separately whether the officers are the city's own or the sheriff's under contract; the FBI's list does not say which.
Outside the city, the Skagit County Sheriff's Office is the county agency. It reported 585 arrests for 2025.
How Many Arrests Mount Vernon Reports
The FBI publishes every agency's monthly arrest counts on the Crime Data Explorer. These are the full-year totals, all offenses, as the FBI held them on October 8, 2026; a year with months missing or not reported is left out.
- Mount Vernon: 1,208 for 2025, 1,149 for 2024, 956 for 2023, 887 for 2022, 785 for 2021 and 1,032 for 2020.
Mount Vernon's 1,208 arrests in 2025 were up 5.1 percent from 1,149 in 2024.
Through July 2026, Mount Vernon reported 562 arrests, against 719 in the same months of 2025.
Across Skagit County, the five agencies with all twelve months of 2025 on file reported 2,817 arrests between them.
Booking: Where People Arrested in Mount Vernon Are Held
A person kept in custody after an arrest in Mount Vernon is held at the county jail, whichever agency made the arrest, apart from the short stay some city departments' own holding cells allow; a person cited and released at the scene is not booked at all. The jail's record of each person held, with the charges, is a public record of the arrest, and the court file takes over from there.
On an average day in 2021 the jail held about 180 people, down from about 310 in 2019. Its rated capacity in 2019, the last year with a capacity figure, was 400 beds, and it ran at 77 percent of it that year. The figures are from the Vera Institute of Justice's Incarceration Trends data.
SearchSystems opened and checked the custody page of the Skagit County Sheriff's Office at skagitcounty.net/Departments/Jail/jailrostermain.htm (page title: Skagit County Jail Roster and Booking Reports), which answered when SearchSystems opened it on September 23, 2026.
That page is the place to look for someone who was booked recently; a person cited and released at the scene, or held only a few hours by a city department, will not be on it.
A sentence of more than a year is served in state prison; the Washington State Department of Corrections lists its inmates at doc.wa.gov/records/incarcerated-data-search/incarcerated-search.
How to Find Out About an Arrest in Mount Vernon
An arrest in Mount Vernon can be traced in three places, depending on where the case stands: the custody page of the Skagit County Sheriff's Office described above, for anyone booked into the county jail; the case index of the Skagit County Superior Court, which shows whether charges were filed and the next court date (the court records page SearchSystems verified is at digitalarchives.wa.gov/Collections/TitleInfo/2388, phone (360) 650-3125); the Prosecuting Attorney, which decides whether an arrest becomes a charge (its page is at skagitcounty.net/Departments/ProsecutingAttorney/dept.htm, phone (360) 416-1600).
Statewide, Washington Courts Search Case Records is the Administrative Office of the Courts' free statewide case search.
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. That record shows what agencies reported to the state, which is wider than one county's court index but can lag it.
Getting a Copy of an Arrest Record in Mount Vernon
The report of an arrest is released by the agency that made it; the jail and the court hold their own records of the same event, but not the report. Under the Public Records Act (RCW 42.56) the agency must answer within 5 business days, and it may charge for copies at 15 cents a page, and set fees for electronic records.
- An arrest by the agency that reports for Mount Vernon: its own records unit.
- An arrest by the Skagit County Sheriff's Office: ask its records unit.
- A defendant who has been charged gets the report through the case: the Prosecuting Attorney, (360) 416-1600, handles discovery for pending cases.
- The court file of a case that was filed: the Skagit County Superior Court, through the court records page at digitalarchives.wa.gov, phone (360) 650-3125.
- Your own statewide record: the same request described above, for your own name.
