Julia Wandelt went viral last month after posting on social media claiming that she thinks she could be Madeleine, who disappeared in May 2007 in Praia da Luz in Portugal.
The 21-year-old from Poland claims to have a freckle on her leg and a speck in her eye in the same places as the British girl, as well as looking similar to parents Kate and Gerry.
