Quote from the woman that took the picture:
"We saw a blonde girl who caught our eye. We both looked at each other. We thought of Madeleine but we didn't think any more about it, as we thought it would be impossible," Torres told Spanish news agency EFE about the possible sighting.

"I've been kicking myself because these 25 days have been lost
The moment I realized, I handed over the photo to the authorities," said Torres.
