Sixteen agonising years may have passed, but Kate and Gerry McCann understandably cling onto a glimmer of hope that their daughter Madeleine could still be alive.
Their beloved eldest daughter Maddie vanished from their holiday apartment in Pria Da Luz on May 3, 2007.
The parents went out for dinner to a nearby restaurant with three other couples, only to return at 10pm to find their three-year-old missing from her bed.
