A senior source close to the inquiry said: "We do not have proof the girl is dead. If we had that kind of evidence we would not be considering the theory she was abducted." The admission amounts to a U-turn. For six months officers have been convinced Madeleine, who was three, died in an apartment in Praia da Luz and her parents disposed of the body using a hire car rented 25 days after she vanished.
But following a meeting with the Forensic Science Service last week, Portuguese detectives have conceded they have no proof to support the theory.
"We are no longer sure that she is dead," a source told Daily Mail sister paper Evening Standard.
The revelation comes as police prepare to reinterview Kate and Gerry McCann, who remain official suspects over their daughter's disappearance from the Mark Warner Ocean Club resort on 3 May. (Daily Mail)
Friends of the couple who were with them at a tapas bar when she vanished will also be questioned.
