For a named Mercer release, the home page explains how to compare the jail event with the court record. State parole or county probation belongs under Post-Release Supervision. Same-day inquiries use the jail because Mercer publishes no official 24-hour feed. A state prisoner belongs in the IDOC offender search, a federal prisoner in the BOP locator, and a documented immigration transfer in ICE ODLS.
