Today marks the four-year anniversary of Madeleine ‘Maddie’ McCann’s disappearance from the Portuguese Algarve resort of Praia da Luz.

Madeleine McCann who was three-years-old when she vanished, has not been seen since May 3, 2007 while her parents dined at a nearby restaurant.

McCann family spokesman Clarence Mitchell said:

”It will be a private day marked with family and friends. The anniversary is normally a very low-key occasion at home for them”.

McCanns fear that Madeline may never be found

However Madeleine’s parents Kate and Gerry McCann have not given up hope of one day finding their daughter.

Kate and Gerry McCann participated in the ‘Miles for Missing People’ 10km charity run held in Regent’s Park, central London on April 2, 2011.

Madeleine’s mother Kate McCann wrote on the Official Find Madeleine Campaign Facebook page yesterday that she still believes her daughter can be found:

“Four years may have passed but our little girl is still missing. And, she is still findable. Your continued kindness and backing could help us achieve this.

On the website Kate, 43, also says she still has “flashbacks to May 2007”

“You just keep thinking that she’s going to be found tomorrow – and here we are four years later.”

Kate McCann has written the book ‘Madeleine’ with help of author JK Rowling, in the hope that it may help in Madeleine’s investigation to promt those with information to come forward.

The book will be released on May 12, on Madeleine’s eigth birthday.
