The disappearance of 11-year-old Madeleine McCann in 2007 from Algarve, Portugal, garnered international attention and eventually became the catalyst for AMBER Alert programs and additional resources to find missing and abducted children in Europe.

The case is the subject of a new Netflix series “The Disappearance of Madeleine McCann.” The missing girl’s mother, Kate McCann, also wrote a book detailing her efforts to get better alert systems for missing children in Europe. “It was clear to Gerry and me that if such a procedure had been in use in Portugal, Madeleine might have been swiftly tracked down,” wrote McCann.
