Mukilteo, Washington, in Snohomish County, has about 21,000 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 Snohomish 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.

Booking: Where People Arrested in Mukilteo Are Held
A person kept in custody after an arrest in Mukilteo 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 2023 the jail held about 520 people, down from about 1,010 in 2019. Its rated capacity in 2023 was 1,244 beds, and it ran at 42 percent of it that year. The figures are from the Vera Institute of Justice's Incarceration Trends data.
