The 30,000 pages of documents were released to Kate and Gerry McCann last week, The Telegraph reports. After a 14-month investigation, police do not know what happened to Madeleine, then 4, when she disappeared from her family's holiday apartment in the Algarve.
"It will be clear to everyone now, that there is absolutely no evidence that suggests Madeleine has been seriously harmed," Gerry McCann said on the Find Madeleine Web site. "Knowing this, we strongly believe that Madeleine is out there and can be found."
The documents list a number of supposed Madeleine sightings and suggest that some of them were not followed up. The most recent occurred in Brussels, and the little girl spotted with a woman wearing a hijab turned out to be the daughter of a local resident walking with her nanny.
