In Italy there is a program about missing people, it's called "Chi l'ha visto?" (Who has seen him/her?).
The presenter tells many stories about young and old, female and male people who suddenly disappear.
Some of these stories are tragedies and missing people are died or killed by someone.
But others have an happy ending and it happens that they are able to find the missing thanks to the help of people that watch TV and call to give informations.
