Possible article title: "New clue found in search for Madeleine McCann at reservoir shrine"

A British couple claims to have found a "shrine" to missing Madeleine McCann near the reservoir in Portugal searched by police last week. The retired pair say they discovered a makeshift memorial, consisting of a photograph of the missing toddler surrounded by flowers and stones, at Christmas in 2007. The couple sent photographs of the shrine to Portuguese detectives but never heard anything back. They contacted German authorities three years ago after Christian Brueckner was identified as a suspect. The police have not commented on the couple's claims, and materials have been sent to Germany for testing.
