Horror evidence discovered in Christian Breuckner’s lair led to the chief suspect being investigated over the disappearance of Madeleine McCann. According to a bombshell new documentary, grim evidence found at his property included images of children in swimming costumes, toddler toys, and sickening child kidnapping stories written by Breuckner, where he describes using chemical ether to abduct a mum and her child.

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.”

According to The Sun’s new documentary, 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 also revealed Brueckner also wanted to “capture something small and use it for days.”

He also threatened it would not matter if “evidence is destroyed afterwards” before adding: “I’ll make a lot of films…hehe.” Police files show the biggest leap forward in the understanding of the case since German police announced in 2020 that Brueckner was the chief suspect in the Madeleine McCann case.

The documentary also revealed how Brueckner refused to answer police questions and failed to give an alibi. Brueckner has not been formally charged over Madeleine’s disappearance or her murder.

Meanwhile, 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.”

It also featured an interview with Irish holiday rep Hazel Behan, 41, who Brueckner was cleared of having raped in 2005 during a trial in Germany last year. The documentary uncovered details that outlines investigators’ fears that Brueckner could end up taking what he knows with him to the grave without any closure being given.

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.

Investigators made limited findings as they searched for any clues related to Madeleine in Praia da Luz.

The probe unearthed limited findings, including animal bones and small materials that have been hauled off for analysis. The area was investigated as lead suspect Christian Brueckner lived in a cottage in the area when Madeleine went missing in 2007.

German investigators were aided by Portuguese police and were seen using diggers and radar to search into the ground. Despite this “nothing of consequence” was discovered.
