This is one of the last photos of Madeleine McCann, right, taken May 3, 2007, less than eight hours before she disappeared. Just shy of her fourth birthday, Madeleine vanished from an apartment in Praia da Luz, a sunny seaside town in the Algarve region of Portugal, where she and her family were vacationing. The night she disappeared, Gerry and Kate McCann, Madeleine's parents, went to dinner with friends at a nearby restaurant. They regularly checked in on Madeleine and her 2-year-old twin siblings, Sean and Amelie, who were napping in the unlocked apartment.  (Kate McCann)

On May 12, 2007, Madeleine turned 4. Her parents asked people to "redouble their efforts" to help find their daughter. The BBC reported that Madeleine's aunt, Philomena McCann, said Gerry and Kate McCann would have a "family day" to honor their missing daughter. (AP Photo)

Gerry and Kate McCann, devout Catholics, visited Pope Benedict XVI May 30, 2007, in Rome. During the emotional meeting, the pope blessed a photograph of Madeleine. "Today, meeting the pontiff was an experience that has caused very mixed emotions for us," Gerry McCann said during a press conference. "In ordinary circumstances, it would be a highlight for any Catholic to meet the pope. Of course it's saddened by the marked realization that our daughter is still missing."  (CityFiles/WireImage/Getty Images)

As word spread about Madeleine's disappearance, the McCanns' hometown of Leicestershire, England, showed its support. Three-year-old Cally prepares to add a yellow ribbon to a floral tribute for missing Madeleine McCann at the Rothley War Memorial May 21, 2007.

A candle is left standing in the spot where yellow ribbons for missing Madeleine McCann were removed from the railings at the Rothley War Memorial at Cross Green in England July 31, 2007. "[It's] not because in any way we feel that we're giving up hope or the search is any less than it was," said Brian Kennedy, Madeleine's great-uncle. "It's as big as ever. In fact, it's more widespread than anything, but [the ribbons have] been on the Green for a long time and the Green doesn't just belong to us, it belongs to everyone."

On August 5, 2007, a dozen Portuguese police conducted a new search of the home of 33-year-old British expatriate Robert Murat, left, one of three suspects named by Portuguese police. His home is located near the hotel from where 4-year-old Madeleine vanished. Police later announced that the search yielded nothing. Murat's mother spoke out in November 2007, telling the BBC that her son was with her throughout the evening of May 3, 2007, the day Madeleine disappeared. British newspaper The Observer reported April 13, 2008, that Murat is seeking record monetary damages from British media for allegedly defaming him. (FRANCISCO LEONG/AFP/Getty Images)

On Sept. 7, 2007, Kate McCann leaves the headquarters of the Portuguese criminal police department after she was questioned in Portimao. Gerry McCann dismissed the suggestion that his wife was involved in Madeleine's disappearance, saying it was "ludicrous" and adding that Kate McCann was "completely innocent."
A family spokesman said that police believe Kate McCann was involved in the accidental death of her daughter, to which Madeleine's grandmother described as "absurd." Days later, Portuguese prosecutors said they found no new evidence to justify further questioning of the McCanns.

On Oct. 25, 2007, Kate and Gerry McCann released a sketch of the man they believe abducted their daughter. The image shows a man carrying a child in his arms and was drawn by an FBI-trained forensic artist from the eyewitness account of Jane Tanner, one of the friends who dined with Gerry and Kate McCann on the evening Madeleine disappeared. Tanner told the BBC she saw the man near the McCanns' apartment complex around 9:15 p.m. Nearly an hour later, Tanner found out that Madeleine was missing.
