Missing persons

A missing person is a person who has disappeared and whose status as alive or dead cannot be confirmed as their location and condition are unknown. A person may go missing through a voluntary disappearance, or else due to an accident, crime, death in a location where they cannot be found (such as at sea), or many other reasons. In most parts of the world, a missing person will usually be found quickly. Criminal abductions are some of the most widely reported missing person cases.

By contrast, some missing person cases remain unresolved for many years. Laws related to these cases are often complex since, in many jurisdictions, relatives and third parties may not deal with a person's assets until their death is considered proven by law and a formal death certificate issued. The situation, uncertainties, and lack of closure or a funeral resulting when a person goes missing may be extremely painful with long-lasting effects on family and friends.

A number of organizations seek to connect, share best practices, and disseminate information and images of missing children to improve the effectiveness of missing children investigations, including the International Commission on Missing Persons, the International Centre for Missing & Exploited Children (ICMEC), as well as national organizations, including the National Center for Missing & Exploited Children in the US, Missing People in the UK, Child Focus in Belgium, and The Smile of the Child in Greece.

A 1993 UK study estimated that 250,000 people had disappeared of which at least 100,000 were under the age of 18. A 1992 report found thousands of women searching for an estimated 60,000 sons, husbands and fathers who had disappeared in Sri Lanka over the previous few years. Most of those missing were believed to have been involved in conflicts between extremist movements and forces associated with the Sri Lankan government.
