The search began on Monday, executed under warrants from German authorities, and targets plots of land in proximity to both the site of Madeleine's disappearance and the last known location of prime suspect, Christian Brückner. Digging operations commenced at a deserted structure where officers have been observed clearing debris and examining wells in the area. Around 30 German officers have joined forces with the Portuguese authorities for this operation, which is anticipated to continue until Friday.

Brückner, currently incarcerated in Germany for unrelated convictions, is being scrutinized by investigators who suspect him of involvement in Madeleine's murder. Despite his repeated denials and lack of charges concerning her case, both German and Portuguese authorities have formally identified him as a suspect. The hope is that the latest searches—amplified by advanced forensic techniques and years of investigation—will yield new evidence or lead to significant breakthroughs as the deadline for Brückner's potential release looms.

The ongoing investigation, known as Operation Grange, has accrued substantial costs to date, and authorities remain committed to exhausting all potential avenues in the search for the missing child, while Madeleine's parents reinforce their pledge to pursue justice unwaveringly. Despite the passage of time, the complex case continues to draw international attention and speculation.
