Police investigating the disappearance of Madeleine McCann could “significantly strengthen” their case against suspect Christian Brueckner following new evidence, according to an expert. According to a harrowing new Madeleine McCann documentary, horrific evidence found at Christian Breuckner’s property included images of children in swimming costumes, toddler toys, and sickening child kidnapping stories.

An 80gb hard drive was found consisting of images and a laptop key, which may have prompted investigators to link the suspect to Madeleine’s disappearance.

The hard drive also placed Brueckner at the heart of the search location in Arades Dam, in Portugal. The documentary revealed that Brueckner also wanted to “capture something small and use it for days”.

Professor of Forensic Science at the University of Kent, Robert Green, believes discovering “mask, guns, and hard drive” may warrant a more “thorough investigation” into Brueckner’s past.

He told The Mirror: “The discovery of items such as a mask, guns, and particularly the hard drive, indicates a potential link to further criminal activity, which may warrant a more thorough investigation of the suspect’s past.

“The rationale behind the renewed search could stem from the ongoing pursuit of justice in the Madeleine McCann case and the hope that any additional evidence could lead to a breakthrough. Investigators continually assess existing evidence and pursue lines of inquiry they believe could be fruitful, especially in cases that have remained unresolved for many years.”

Furthermore, a newly uncovered letter from lead suspect Brueckner is said to mock German police’s attempts to link him to the disappearance of Madeleine McCann.

In the handwritten note, seen by German newspaper Bild, he reportedly writes: “Are there any traces of her in my vehicle? Any other traces of her in my possession? Photos? Is there a body? No, no, no.”

A document also put the suspect at the location of a search for Madeleine McCann, where he allegedly said “she did not scream” as he discussed the British toddler with an associate. He also reveals a harrowing kidnapping story, including: “A very small girl enters the room. She’s definitely not older than five.”

The most recent search for any clues related to the search for Madeleine McCann lasted three days in Praia da Luz, last week. It happened close to where Brueckner is known to have had camped.

Brueckner spent time in the Praia de Luz area of Portugal between 2000 and 2017. His home was just one mile away from the Ocean Club, where the McCann family were staying when Madeleine vanished on May 3, 2007.

Years later, investigators reportedly found his mobile phone had received a call close to the holiday flat complex around one hour before the three-year-old was reported missing.
