Finding Someone in Custody in Jefferson Parish
A person kept in custody after an arrest in Jefferson Parish is held at the parish jail, run by the Jefferson Parish Sheriff's Office, whichever agency made the arrest.
SearchSystems opened and checked the custody page of the Jefferson Parish Sheriff's Office at jdpso.org/inmate-roster/filters/current/booking_time=desc/1 (page title: Inmate Roster | Jefferson Davis Parish Sheriff's Office | Sort Booking Time | Descending | Page 1), phone 337.821.2100, which answered when SearchSystems opened it on September 30, 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.
