During the search, police combed 60,000 square meters of land. "Forty-one ground anomalies were identified by both aerial survey and ground analysis which were then investigated fully."
Police determined that there was no new evidence. "This recent work is part of ensuring that all lines of inquiry are progressed in a systematic manner and covers just the one hypothesis that she was killed or buried locally," the police said Wednesday.
The news was welcomed by McCann's partents, Kate and Gerry, who said in a statement, "We are further encouraged that, despite the intensive searches, no trace of Madeleine has been found and this reinforces our belief that she could still be alive."
The parents also expressed appreciation for the work of British and Portuguese law enforcement. "As parents of a missing child, we have always wanted all reasonable lines of inquiry to be followed and it is gratifying to know that a substantial amount of work will take place over the coming months with close cooperation of the British and Portuguese authorities. We would like to thank all those involved for their efforts and the members of the public who have come forward with information."
The three year-old disappeared on May 3, 2007 while on vacation with her family in Portugal. She was last seen asleep in her room at their vacation apartment.
