Further information: § Smith sighting
In 2008 Madeleine's Fund hired Oakley International, a Washington, D.C.-registered detective agency, for over £500,000 for six months.[231][236][237][238] (The company owner, Kevin Halligen, was arrested in 2009 in connection with an unrelated fraud allegation.[239]) Oakley sent a five-man team to Portugal. Led by Henri Exton, a former British police officer who had worked for MI5, the team engaged in undercover operations within the Ocean Club and among paedophile rings and the Roma community.[231]
Exton questioned the significance of the Tanner sighting of a man carrying a child at 21:15 near apartment 5A, and focused instead on the Smith sighting at 22:00—the sighting by Martin and Mary Smith of a man carrying a child near the McCanns' apartment that night. The Oakley team produced e-fits based on the Smiths' description. This was a sensitive issue, because in September 2007 Martin Smith had watched footage of the McCanns arriving in the UK from Portugal, and believed he recognized Gerry McCann as the man he had seen with the child in Praia da Luz. Smith came to accept that he was mistaken: at 22:00 witnesses placed Gerry McCann in the tapas restaurant. Nevertheless, publication of the Smith e-fits, which bore some resemblance to Gerry, would have fed the conspiracy theories about the McCanns.[61]
Exton submitted his report to Madeleine's Fund in November 2008, but the fund told Exton that the report and its e-fits had to remain confidential. The relationship between the company and the fund had soured, in part because of a dispute over fees, and in part because the report was critical of the McCanns and their friends; it suggested that Madeleine may have died in an accident after leaving the apartment herself through its unlocked patio doors.[61] The fund passed the e-fits to the police—the Polícia Judiciária and Leicestershire police had them by October 2009, and Scotland Yard received them when they became involved in August 2011[240]—but did not otherwise release them. Kate McCann did not include them with the other images of suspects in her book, Madeleine (2011), although she suggested that both the Tanner and Smith sightings were crucial.[61]
Scotland Yard released the e-fits in 2013 for a BBC Crimewatch reconstruction. After it had aired, The Sunday Times published that the McCanns had had the e-fits since 2008.[61] In response the couple sued the newspaper for having implied (wrongly) that they had not only failed to publish them but had withheld them from the police. The newspaper apologized and paid £55,000 in damages.[240][241]"
