Portuguese Dam Site Holds Clues to McCann Disappearance, Says German Prosecutor.

Police from Portugal, Germany, and Britain are searching for clues regarding the disappearance of Madeleine McCann, who went missing in Portugal in 2007. The search is focused on the Arade dam, where a lead suspect in the case often stayed. German prosecutor Christian Wolters said that they have indications that evidence could be found there, but it doesn't come from the suspect. The search is expected to end on Wednesday or Thursday. Madeleine's parents are not commenting due to the active investigation.
