At around 8.30pm on May 3, 2007, Kate and Gerry McCann left their three sleeping children in their holiday apartment in the quiet Portuguese resort of Praia da Luz and headed out for dinner.
They thought that Madeleine, three, and 18-month-old twins, Sean and Amelie, would be safe just 83 metres from where they were dining at a tapas restaurant with the group of friends they were holidaying with.
Throughout the evening, the adults took it in turns to check on the kids.
At 10pm, it was Kate McCann’s turn.
When she arrived at apartment 5A, she knew immediately something was wrong.
Madeleine was gone.
What happened next is well documented. The story of the blonde toddler’s unexplained disappearance became a global news story.
This May, will mark 15 years since the wide-eyed toddler's disappearance, and on May 12, it would've been her 19th birthday.
This week, Kate and Gerry McCann welcomed news that a German man has been formally made a suspect over their three-year-old's disappearance.
It is the first time Portuguese prosecutors have identified an official suspect in the case since Madeleine's parents were named suspects in 2007. They were later cleared.
Posting on the Official Find Madeleine Campaign Facebook page, Kate and Gerry wrote: "We welcome the news that the Portuguese authorities have declared a German man an 'arguido' in relation to the disappearance of our beloved daughter Madeleine.
