An ICE "arrest detainer" (Form I‑247/I‑247A) is a non‑binding DHS request asking the jail or law enforcement agency holding a person to: notify ICE before release and hold the person for up to 48 hours (excluding weekends/holidays) so ICE can assume custody. If the local agency honors it, ICE officers take custody in a secure setting; if ICE does not assume custody within 48 hours the agency must release the person. Local agencies are not legally required to honor detainers in all jurisdictions.
The VOICE Office (Victims of Immigration Crime Engagement) is an ICE/DHS victim‑service unit that helps victims/families of crimes with an immigration nexus by: explaining immigration enforcement/removal processes; registering victims for automated custody‑status notifications (DHS‑VINE); providing releasable criminal/immigration history where allowed; and referring victims to local social‑service and victim‑service resources via a toll‑free hotline (1‑855‑488‑6423).
Not determinable from the DHS/ICE release: the statement says ICE "lodged an arrest detainer" to ensure federal authorities are notified but does not state whether Guzman remained in local custody or was transferred to federal custody. No source was found that confirms a transfer.
If Guzman is convicted of illegal reentry after removal, he could face federal criminal penalties under 8 U.S.C. §1326 (unlawful reentry), which carries possible prison time (statutory ranges depend on prior removals and convictions) and a subsequent removal order; separate civil immigration consequences include initiation or reinstatement of removal proceedings and ineligibility for most immigration relief. Specific sentencing depends on the felony history and facts of the case.
The violent criminal charges listed (rape, aggravated child molestation, home invasion, aggravated assault, burglary, etc.) are state felonies and will be prosecuted by local/state prosecutors (Bulloch County/Georgia) in state court; immigration enforcement (detainer, removal) is federal (DHS/ICE) and immigration proceedings would be handled in federal immigration courts (EOIR) if ICE takes custody or initiates removal. Criminal trial and state court proceedings occur in Georgia courts; any federal immigration proceedings occur before EOIR immigration judges.
DHS/ICE determines prior removals using federal immigration records and databases (A‑Number files, CBP/ICE/USCIS records and Intergovernmental Automated Fingerprint Identification System matches). ICE generally verifies prior removals via agency records (Alien Registration/A‑Number, removal orders, entry/exit and enforcement databases) and biometric and case history evidence before issuing a detainer.
