Free online inmate searches are available from several sources. VINELink, or the Victims Information and Notification Everyday network, has information for most states. The Department of Corrections in many states has an inmate search portal with varying amounts of information on offender status.
For federal immigration detainees at any correctional facility, the U.S. Immigration and Customs Enforcement agency has a free portal at its website. VINELink offers a service to keep individuals updated on an offender's status and court proceedings, as well as court rulings and changes in inmate status. It also offers contact information for victim assistance, juvenile resources, crime victims' rights and justice resources.
