Missing Persons reports are filed daily, thankfully most people return safe and well within 72 hours. However thousands every year do not return.
The families and friends left behind suffer a never ending nightmare of not knowing what has become of their loved one.
The police have the primary role of searching for a missing person, then there are organisations set up with databases updating details of people, the circumstances in which they disappeared, photographs (including age progression) and general physical characteristics.
The following are a small percentage of the missing persons cases throughout the world. There are links to the local police department if you have any information on the whereabouts of these people.
