The ongoing trial has attracted significant media attention due to Brueckner's connection to the McCann case, although this case is not the focus of the current proceedings.

Madeleine McCann was just three years old when she disappeared from her family's holiday apartment while her parents dined nearby.

Brueckner is currently on trial for unrelated sex offenses in Portugal, including the rape of an Irish tour representative and a teenage girl, while denying all charges.

He has a lengthy criminal history, including a conviction for raping an American woman in 2005 and multiple allegations of sexual offenses against minors in Portugal.

Operation Grange, the investigation into McCann's case, has cost over £13 million and has included Brueckner as a person of interest since 2020.

Concerns are growing over the possibility of Brueckner being acquitted in his upcoming trial, which is set to conclude in December.

Christian Brueckner, a convicted sex offender, is the prime suspect in the 2007 disappearance of three-year-old Madeleine McCann, who vanished during a family holiday in Portugal.

In 2020, German authorities identified Brueckner as a suspect, and he was formally named as such by Portuguese prosecutors in 2022.

Recent testimonies from Brueckner's former cellmate, Laurentiu Codin, revealed that Brueckner confessed to abducting a child in Portugal, claiming he entered through an open window.

Brueckner mentioned being accompanied by another person during the incident, with whom he had an argument before they parted ways.

Detectives have uncovered emails linked to Brueckner that may connect him to McCann's case, containing disturbing content related to child abuse.

Despite extensive investigations costing millions, no one has been charged in connection with Madeleine's disappearance.
