On the evening of May 3, 2007, Gerry and Kate McCann returned to their resort apartment in Portugal's Algarve to every parents' worst nightmare—their daughter, three-year-old Madeleine Beth McCann had vanished from her room. Her disappearance sparked a worldwide manhunt. Poster campaigns, distraught pleas from the parents, and frenzied media coverage all ensued—but still Madeleine's whereabouts remain a mystery. Portuguese police initially commenced a search for Madeleine's abductor, but as the case dragged on the waters became muddied and controversy dogged the investigation—British police were called in, suspects entered and departed the frame, sightings of Madeleine were reported from around the world, accusations about the thoroughness and competency of the Portuguese police were made, and the McCanns were scrutinized in the full glare of the media spotlight—with the Portuguese police even declaring Gerry and Kate suspects.
