Locating missing or wanted persons relies on combining different information systems to cross-check identities and reach across jurisdictions. AFIS helps identify individuals by comparing fingerprints, including latent prints. NCIC provides nationwide data on wanted and missing persons and related alerts, offering broad reach beyond a single agency. VCIN links Virginia agencies for real-time access to state-level warnings, warrants, and missing person notices, giving timely local and regional visibility. CCH, the Central Criminal History, provides official criminal history records to verify identities and confirm prior warrants or convictions. Using all four resources ensures you can confirm who you’re dealing with, check for warrants, locate the person across state and national boundaries, and verify essential details quickly. The other options leave out one or more critical data sources, so they don’t provide the complete picture needed to locate someone effectively.
