Missing person

A missing person is someone reported to an agency as having unknown whereabouts under the applicable reporting criteria. The record identifies a concern requiring assessment; it does not automatically establish a crime, explain why the person is missing, or show that a public alert was issued. The person's age, circumstances, and available information affect the record's meaning.

A report is different from an alert

Agencies can record a missing-person report without issuing a broad public alert. Alert systems apply their own eligibility rules, while an investigation can involve information not included in a public listing. Absence from an alert page does not establish that no report exists.

California's Department of Justice expressly states that there is no waiting period for reporting a person missing and describes that state's acceptance requirements. Mesa's public guidance also rejects a supposed 48-hour wait. These are directly checked official statements; the glossary does not invent a waiting period.

A dated public extract remains a snapshot. The person may have been located after the extract was produced, so current status needs a current source.

Example

Hypothetical example: A family reports that an adult relative has not arrived as expected and cannot be reached. The agency creates a missing-person record and gathers identifying and last-known-location information. Later, staff confirm the person has been located and update the case.

The report documents a concern and later resolution in this example. It does not establish an abduction or explain the absence. A dataset retaining the original entry can still show that a report was made even after the person is no longer missing.

Common confusion

A welfare check requests an assessment of well-being, often at a known or suspected location. A missing-person report concerns unknown whereabouts under the agency's criteria. The two can relate but are not identical.

A missing-person case is also different from a public alert or a finding of criminal involvement. A person may have several associated records, and a repeat report does not automatically identify a different person.

Interpreting totals and status

Separate reports received during a period, people still missing on a date, and unique people reported missing. Determine how repeat reports and located-person updates are handled. Do not treat an unresolved public entry as proof of harm or voluntary absence. For an actual missing-person concern, use the responsible agency's current reporting guidance rather than waiting for a glossary or public listing to update.
