Police are searching a reservoir in Silves, Portugal with sniffer dogs in connection to the disappearance of Madeleine McCann. The British toddler went missing in May 2007 while staying with her family in a Portuguese resort, and the reservoir is about 31 miles inland from that location. German prosecutors have identified Christian Brueckner, a convicted child abuser and drug dealer in Germany, as a suspect in the case and police from Germany and Britain are assisting with the current search. Despite extensive media attention and worldwide appeals for information, the case remains unsolved after 16 years.
