Madeleine McCann

Netflix's "The Disappearance of Madeleine McCann" talks about self-described spy Kevin Halligen, who did plenty of damage to the missing girl's case.

Brian Kennedy, a wealthy Scottish businessman, bankrolled several private investigations to help find the missing 3-year-old girl. How did he and his son Patrick become involved in the case?

“Keep the faith. Keep hope alive,” Ed Smart told Kate McCann a year after Madeleine had vanished from a resort town in Portugal.

Sergey Malinka doesn't remember a phone call from Robert Murat that had police linking him to the case of missing 3-year-old Madeleine McCann. A decade later, Malinka claims the investigation into him has ruined his life.

11-year-old Rui Pedro Teixeira Mendonça went missing in 1998. His case serves as a foil to that of Madeleine McCann's in Netflix's new series.

“Why would you publish something like that?” asked former chief investigating coordinator Gonçalo Amaral.

Praia da Luz was the site of British toddler Madeleine McCann's disappearance in 2007. Despite the grim connotations, the picturesque beach remains a top destination for British tourists.

The British-Portuguese real estate consultant's eagerness to help in the case put him on the police's radar, but they turned up no evidence that he was involved. 

Madeleine McCann vanished from a resort town in Portugal in 2007 at the age of 3. Hers remains one of the most famous missing persons cases in the world.
