Madeleine McCann disappeared during a family vacation from an apartment in Praia da Luz, Portugal. Her parents left the 3-year-old and her two brothers sleeping, as they had dinner at a nearby restaurant. The main suspect in her disappearance is 44-year-old Christian Brueckner. He's currently in a prison for the rape of a tourist. Brueckner has also been arrested for pornography and abuse of a minor. Investigators found thousands of images of child porn at a property owned by him. They also found that Brueckner had been in the area at the time of McCann's disappearance.
