Portuguese, German and British investigators begin their second day of searching on the banks of a reservoir in southern Portugal, in a new effort to uncover information on the 2007 disappearance of British toddler Madeleine McCann. Three years old at the time, McCann went missing from her family's holiday apartment in Praia da Luz and, despite a huge international manhunt, no trace of her has been found and no one has been charged over the disappearance.
