Which of the following is NOT a category of Missing Person?

The classification of missing persons is critical for effective law enforcement response. In this context, "Known" is not recognized as a formal category of missing persons. The established categories serve specific purposes in understanding the circumstances around an individual’s disappearance.

The category of "Endangered" applies to individuals who may be at risk due to various factors such as age, health, or environmental situations. "Involuntary" refers to individuals who are missing due to abduction or coercion, indicating that they did not leave voluntarily. Meanwhile, the "Disability" category includes those who are missing due to mental or physical limitations, impacting their ability to navigate their environment safely.

By understanding these recognized classifications, law enforcement and other relevant agencies can prioritize their responses and tailor their search efforts appropriately. The absence of "Known" as a category highlights its lack of formal recognition in the NCIC framework, making it the accurate choice for the question.
