Madeleine McCann search ends with no breakthrough.

Police investigating the disappearance of Madeleine McCann are expected to end their search at the Algarve reservoir in Portugal after being ordered to stand down. The search began on Tuesday after a "very credible source" informed German detectives that key suspect Christian Brueckner visited the reservoir "some days" after Madeleine vanished. Investigators believe the 45-year-old killed Madeleine, then aged three, after abducting her from a holiday apartment.
