Disturbing new evidence uncovered at Christian Brueckner’s abandoned lair in Germany has intensified the investigation into the disappearance of Madeleine McCann. 

Madeleine was three when she vanished from the Portuguese resort of Praia da Luz on the Algarve while on a break with her siblings and parents Kate and Gerry McCann. 

The findings, revealed in a Sun investigation, shed light on Brueckner’s disturbing obsessions and potential involvement in the case.

The German rapist and paedophile, who was identified as a prime suspect, was cleared of unrelated sex attacks in the same area Madeleine vanished from last year.

However, it has now been revealed that in 2016, German police discovered a stash of USB sticks and memory cards buried beneath the body of Brueckner’s dead dog at a disused factory he owned in Neuwegersleben. 

The storage devices contained thousands of files, including images of child abuse, stories detailing fantasies of abducting young girls, and records of Skype chats with other paedophiles. 

One story described drugging a mother and daughter outside a pre-school and abusing a four-year-old blonde girl.

These materials have led investigators to believe that Brueckner may have been involved in Madeleine’s disappearance and death.

Further searches of the compound revealed over 75 children’s swimming costumes, toys, small bikes, and masks. 

Three unlicensed firearms and ammunition were also found, along with bottles of substances suspected to be chloroform or ether – chemicals associated with abductions. 

A satnav traced Brueckner’s movements in the Algarve, including the Arade Dam, approximately 35 miles from where Madeleine vanished in Praia da Luz .

A hard drive containing photographs taken in Portugal is believed to be crucial in persuading investigators that Madeleine died shortly after her disappearance in May 2007. 

Additionally, an insurance claim signed by Brueckner indicates he was at a festival in Orgiva, Spain, in April 2008, where he allegedly told a friend that Madeleine ‘did not scream’ .

Despite these findings, German prosecutors have yet to charge Brueckner in connection with Madeleine’s disappearance. 

Brueckner is currently serving seven years for raping an elderly American woman in the Algarve the year before Madeleine disappeared and he is due to be released later this year.

A Home Office source told MailOnline: ‘The ongoing police investigation into the disappearance of Madeleine McCann, known as Operation Grange, is an operational matter for the Metropolitan Police Service’ 

Prosecutors are awaiting a final judgement on his acquittal last October before deciding on an appeal, but Brueckner’s lawyers have told MailOnline it ‘only has a ten per cent chance of succeeding’.

Just last month MailOnline revealed that the budget for detectives investigating the disappearance of Madeleine McCann had been slashed.

They have been granted a further £108,000 to carry on the search for her – a drop of £84,000 on the amount awarded last year.

The money was approved in April following a request from the Metropolitan Police’s Operation Grange team who were specifically tasked with finding the toddler.

With the latest £108,000 Operation Grange has spent almost £13.5million investigating the case – prompting some to question whether it is viable considering no arrests or charges have been made.

The money comes from a special Home Office fund and is reviewed annually with Operation Grange making a request which is submitted and then considered.

Last week marked the 18th anniversary of her disappearance on May 3, and also her 22nd birthday but there has been no real breakthrough in the hunt.
