A recent article from the Telegraph regarding the efits :
http://www.telegraph.co.uk/news/newstopics/madeleinemccann/10391348/Madeleine-McCann-is-there-hope-at-last.html" Instead, detectives are now focusing their efforts on a second man seen carrying a child towards the beach just minutes before Kate McCann went to check on Madeleine. An Irishman, Martin Smith, and his wife reported seeing him at the time. Their e-fits, which have only now been released, were originally produced by a private detective agency which was hired by the McCanns in 2008 when they became dissatisfied with the Portuguese police inquiry.
At the time, though, it was not published, partly because Portuguese detectives thought the other theory more viable, and partly because Mr Smith himself said he thought the man he had seen looked like Gerry McCann, whom several other witnesses had already said had been at the restaurant table at that point.
Now the later sighting is being taken seriously. While DCI Redwood stressed that it could be a yet another innocent holidaymaker carrying his child, it is the key public line of inquiry, if only because of the absence of anything else. Yet it also means that what could be the key e-fit lay under wraps for several years. "It was passed to the Portuguese police at the time and for whatever reason they decided to nothing whatsoever with it," said one source close to the McCann investigation. "It was then handed to the Met two years ago, and they have now deemed it worthy of publication, but frankly it should have been out there a long time ago."
