Finding Someone in Custody in Troutdale
A person kept in custody after an arrest in Troutdale is held at the county jail, run by the Multnomah County Sheriff's Office, whichever agency made the arrest.
SearchSystems opened and checked the jail page of the Multnomah County Sheriff's Office at mcso.us (page title: Multnomah County Sheriff's Office), which answered when SearchSystems opened it on September 24, 2026.
That page is the office's jail information page rather than a roster.

From the Jail to State Prison
A sentence of more than a year is served in state prison, not the jail; the Oregon Department of Corrections lists its inmates at oregon.gov/doc/victim-services/pages/offender-search.aspx.
