A thorough investigation has allegedly revealed substantial evidence discovered at the property of Christian Brueckner, the primary suspect in the disappearance of the British girl 18 years ago, though he has denied all involvement.
These alleged findings provide a disturbing insight into the suspect’s activities and potential connection to the case.
German authorities reportedly conducted an extensive search of an abandoned factory purchased by Brueckner in 2008, just one year after Madeleine’s disappearance.
The investigation began unexpectedly in 2016 when it’s said ‘a dog ran onto the property and appeared to find a grave,’ which led to a significant discovery beneath Brueckner’s deceased pet dog – ‘a wallet with six USB sticks and two memory cards,’ The Sun reports.

Authorities deployed approximately 100 officers to conduct an extensive search of a compound in Neuwegersleben, central Germany, following the discovery of digital storage devices believed to contain disturbing material.
What investigators reportedly uncovered paints a troubling portrait of the suspect, who is already under scrutiny in connection with the disappearance of Madeleine McCann.
According to sources, a hard drive retrieved from the scene contained photographs taken in Portugal that German authorities now consider critical to their investigation. These images have reportedly led investigators to conclude that “Madeleine died shortly after her disappearance in May 2007.” The images remain under wraps, with officials citing their sensitive nature, but they are said to constitute compelling evidence.
Investigators also allegedly recovered written documents in which the suspect, Christian Brueckner, described drugging a mother and daughter outside a preschool, as well as abusing a young blonde girl around the age of four.
Additional evidence is said to include records of Skype conversations with other individuals sharing similar criminal interests. In one alleged exchange, Brueckner reportedly expressed a desire to “capture something small and use it for days.”
The search is also believed to have uncovered a disturbing cache of children’s items at the suspect’s residence—despite him having no children. These reportedly included more than 75 children’s swimsuits, numerous toys, and small bicycles.
Authorities further allege they found a case containing images of girls aged four and five.

Investigators reportedly discovered ‘three black-market guns and ammunition’ during their search, raising further concerns about the suspect’s intentions and activities.
A mask was found along with manipulated photographs of Brueckner.
Additionally, ‘creepy photographs show Brueckner at a key location of interest for Madeleine investigators.’
Some images show him ‘modelling a mask and even posing naked at the Arade Dam, 35 miles from Praia da Luz,’ which authorities searched in 2023.
Navigation data recovered from a satellite navigation device revealed Brueckner’s ‘pattern of movements around the [Arade Dam] site in the years after Madeleine vanished,’ establishing his connection to locations relevant to the investigation.
Investigators found a Jaguar matching the description of Brueckner’s vehicle with bottles of unidentified substances inside.
Authorities: “Destroyed them without testing, but speculate that kidnap chemicals, chloroform, or ether, could have been in the haul.”
This speculation is particularly concerning as in his stories, Brueckner allegedly fantasized about a kidnapping using ether.

A key piece of evidence is an insurance document filled in and signed by Brueckner that confirms he crashed his motorhome at the festival in Orgiva, Spain.
This corroborates witness Helge B’s claim that Brueckner made statements at this festival suggesting involvement in Madeleine’s disappearance, allegedly saying the girl ‘didn’t scream.’
A metal suitcase discovered during the 2016 search allegedly contained ‘chilling photographs of young girls’ along with a list of phone numbers. An address book was also found nearby.
Following these discoveries, Brueckner was convicted of an unconnected child abuse allegation within months.
The case continues to develop. Brueckner was acquitted of all claims in October 2024 regarding separate allegations, though prosecutors launched an appeal with a decision still pending.
Without further legal action, Brueckner is scheduled to be released from custody on September 17, 2025.
Prosecutors would require an arrest warrant for a retrial over claims from last year, or over the McCann case, to prevent his release.
