Authorities have relaunched searches for Madeleine McCann, the British girl who disappeared in 2007, with significant police activity taking place in Portugal. The new investigations are focused near Praia de Luz, the site where she was last seen. Both Portuguese and German police are involved, conducting searches near the former home of a prime suspect and other locations of interest. This new initiative reflects hope for finding crucial evidence in a case that has captivated the public for years.
