Disappearance of Madeleine McCann
Madeleine was on holiday with her parents, her two-year-old twin brother and sister, and family friends. She and the twins had been left asleep at 20:30 in a ground floor apartment, while the McCanns and friends had dinner in a restaurant  away. The parents checked on the children every so often, until it was discovered Madeleine was missing at 22:00. Over the next few weeks, the Portuguese police started to believe that Madeleine had died in an accident in the apartment and the parents had covered it up.
