Dayton arrests are held in Walla Walla, so the roster belongs to that jail. Here is a quick way through it:

1. Open the roster page and choose the current PDF.
2. Check the date on the file to see how recent it is.
3. Press Ctrl+F (or the find option on your phone) and enter the surname.
4. Test a nickname, middle name or other spelling.
5. On a match, copy down everything in the row before you call anyone.

The jail's inmate information line, 509-524-5430, can confirm what you found.

These are the usual explanations:

• Booking is slow. The files change on weekdays only, so a fresh arrest can lag by a day or longer.
• Ticket instead of jail. Deputies sometimes write a citation with a hearing date rather than make the long drive to Walla Walla.
• Already free. A promise paper or a posted bond may have ended the stay.
• Moved on. A different county, state prison or federal office could hold them now.
• A minor. Young people are kept apart from adults.

Phone the jail office, 509-524-5431. You can also try the Sheriff's Office, 341 E. Main St., Suite 1, Dayton, WA 99328, 509-382-2518.

The Dayton jail shut its doors in March 2023. Adults now go to the Walla Walla County Corrections Department, 300 West Alder Street, Walla Walla, WA 99362, 509-524-5431. It also serves Walla Walla and College Place police and the Walla Walla County Sheriff. For work release, an annex, a city lockup or housing by men, women or intake, ask the jail where the person sleeps.

An arrest by a neighboring agency could mean its own jail holds the person first. Children are taken to a youth center, explained near the end. Federal, ICE and state custody each get their own answer.

Look inside the roster PDF files to see whether any photo appears, because the roster page itself does not say. In Washington, booking photos from jails are private under RCW 70.48.100, except that police may use them in a case and images of people convicted of sex crimes may be released. Ask the arresting agency. The Sheriff's Office, 341 E. Main St., Suite 1, Dayton, WA 99328, 509-382-2518, can speak for arrests by its own deputies.

• If you need an ICE photo, ask for it on ICE's records site.
• Federal mugshots stay private. The sole exception is a fugitive's picture, which the U.S. Marshals Service sometimes shares.

Washington VINE is free, runs around the clock and covers every city and county jail in the state, refreshing every 15 to 30 minutes. Register on VINELink or phone 877-846-3492. VINE leaves out youth detention and gives no court news.

The roster page links to VINE as well. Because the PDF files change only on workdays, VINE tends to speak up first.

Washington's rules for courts begin by freeing a person on a written pledge to come back. A judge may add limits or set a bond, always choosing the lightest terms that work. A first hearing is due before the next court day ends, often on a video screen. After a domestic violence arrest the person remains held until a judge decides.

• For local charges, pay in business hours at the Superior Court Clerk, 341 E Main St, Suite 2, Dayton, WA 99328, or at the District Court office listed below. Off hours, pay at the Walla Walla jail.
• Payment may be cash, or a bond bought from a company the courts have approved.
• Arrested on another county's warrant? Only cash, at any hour, at the jail.
• The Sheriff's page names GovPayNet for cash bail from afar.
• Before you hire a bondsman, check the license through the Department of Licensing and get fees on paper.

Our bail page goes deeper, and the Washington bail laws guide covers the statewide rules.

At the first hearing, say that you cannot afford counsel. The court screens each person. Any one of these can qualify a person under RCW 10.101.010: certain public aid, an income of 125 percent of the poverty level or lower, or a likely legal bill beyond their means. Our court research says the county hires contract lawyers, and the clerk can say who was named.

An ICE detainer (Form I-247A, 8 CFR 287.7(d)) asks a jail to keep someone up to 48 hours after they would otherwise be released. State law at RCW 10.93.160 stops a local jail from keeping anyone solely on an immigration warrant or detainer that is civil in nature, or only to check where they were born. ICE also needs written consent to interview an inmate about a noncriminal matter. Local 287(g) agreements are not allowed under state law.

Children skip the adult jail entirely. Their cases go to Juvenile Court, a part of Superior Court, 341 E Main St, Suite 2, Dayton, WA 99328, 509-382-4321. Detention happens at the Juvenile Justice Center, 455 West Rose Street, Walla Walla, WA 99362, 509-524-2800.

When charges are not yet filed, a judge must look at the detention within 72 hours. The count skips Saturdays, Sundays and legal holidays (court rule JuCR 7.3). Otherwise the child is released. VINE leaves out youth detention, so ring the center.
