Madeleine McCann, a four-year-old girl, went missing in 2007 from an apartment in Praia da Luz, Portugal, while her parents were out for dinner.
Her disappearance became one of the most widely reported missing person cases in history. Despite years of investigation, her whereabouts remain unknown, though her parents continue to hope for her return.
In 2020, German prosecutor Hans Christian Wolters suggested that Madeleine was likely murdered in Portugal by suspect Christian Brueckner, a convicted pedophile serving a prison sentence for unrelated crimes.
