Finding Someone in Custody in Livingston County
A person kept in custody after an arrest in Livingston County is held at the county jail, run by the Livingston County Sheriff's Office, whichever agency made the arrest.
SearchSystems opened and checked the custody page of the Livingston County Sheriff's Office at livcoso.org/inmate-roster/filters/current/booking_time=desc/1 (page title: Inmate Roster | Livingston County Sheriff's Office | 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.
