#6: Madeleine McCann, the Most Widely Publicized Missing Child Story
Madeleine McCann, a three-year-old British girl, disappeared in 2007 while holidaying in Portugal with her family. Her parents, Kate and Jerry, discovered her missing after dinner, sparking immense public interest and an ongoing investigation.

Since Madeleine’s disappearance, the Met Police have dedicated over $12 million to the investigation without filing any charges. Suspicion briefly fell on Kate and Jerry, but they were cleared in 2008. A 2019 Netflix documentary further highlighted the case.
