Finding Someone in Custody in Lavon
A person kept in custody after an arrest in Lavon is held at the county jail, run by the Collin County Sheriff's Office, whichever agency made the arrest.
SearchSystems opened and checked the custody page of the Collin County Sheriff's Office at collincountytx.gov/sheriff/inmate-information (page title: Inmate Information), phone (972) 547-5100, 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.
