EXCLUSIVE: PARENTS OF VANISHED THREE-YEAR-OLD MADELEINE McCANN SPEAK OUT, ON ABC NEWS' "20/20," FRIDAY, MAY 2

Elizabeth Vargas Anchors Report on One-Year Anniversary of Disappearance, Which Remains Front-Page News Worldwide

On the one-year anniversary of their daughter Madeleine's disappearance, Kate and Gerry McCann speak exclusively about the night three-year-old Madeleine vanished without a trace while on a family vacation in Portugal. Since January, the McCanns�who remain official suspects�granted a British documentary crew unprecedented access inside their home and their lives, as they uncover new details about what happened that night, campaign for a European Amber Alert and show how the family is coping today. Hours before Madeleine disappeared, why did the McCanns miss a warning sign from their daughter that something might be wrong? Why did they leave their three children alone in an unlocked apartment? Why did they show little emotion in public after their child went missing? And why does a cloud of suspicion still hover over them? Elizabeth Vargas anchors this intimate portrait of the McCanns and their story, in their words, on "20/20," FRIDAY, MAY 2 (10:00-11:00 p.m., ET) on the ABC Television Network.

ABC News acquired the documentary from Mentorn Productions and ITV.

"20/20" is anchored by Elizabeth Vargas and John Stossel. David Sloan is executive producer.
