What type of missing persons are included in NCIC files?

The inclusion of both adults and children in NCIC files under specific categories demonstrates the breadth of the National Crime Information Center's mission to assist law enforcement agencies in locating missing persons. This approach recognizes that individuals of all ages can go missing for various reasons, which can include voluntary disappearance, abduction, or other circumstances that necessitate law enforcement action.

The validity of this option lies in its comprehensive nature, allowing authorities to track not only missing children, who often receive specific attention due to the increased risks they face, but also missing adults, who may be equally vulnerable to various situations. By encompassing a wider range of cases, NCIC helps ensure that all missing persons are given appropriate visibility and investigative support, thus increasing the chances of recovery.

The other options are limited in scope, either focusing solely on one demographic or a specific circumstance, which would neglect critical cases that do not fit those narrow criteria. Therefore, the correct option reflects the essential inclusivity of the NCIC's mission in addressing missing persons cases regardless of age or situation.
