Finding Someone in Custody in Lewis County
A person kept in custody after an arrest in Lewis County is held at the county jail, run by the Lewis County Sheriff's Office, whichever agency made the arrest.
SearchSystems opened and checked the custody page of the Lewis County Sheriff's Office at lewiscosheriff.org/inmate-roster/filters/current/booking_time=desc/1 (page title: Inmate Roster | Lewis County Sheriff | Sort Booking Time | Descending | Page 1), which answered when SearchSystems opened it on September 23, 2026.
That page is the place to look for someone 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.
The Lewis County Jail by the Numbers
