Madeleine McCann suspect Christian Brueckner breaks silence in prison letter

The key suspect in the disappearance of Madeleine McCann has slammed the police investigation as a “scandal” in a letter from jail.

A convicted paedophile who is the prime suspect in the disappearance of British girl Madeleine McCann has broken his silence, reportedly penning a letter from prison slamming police investigators.

German rapist and child sex offender Christian Brueckner was identified as the key suspect in the abduction and murder of Madeleine last year, more than a decade after the three-year-old mysteriously vanished during a family holiday in Portugal.

In a handwritten letter dated May 8, Brueckner allegedly slammed the investigation as a “scandal” and called on prosecutors to “resign” for “persecuting an innocent person”, German newspaper Bild reported.

The 44-year-old was revealed as the prime suspect last June, with German authorities treating the case as a murder investigation and claiming they have “concrete evidence” the British girl is dead.

Despite the claims, Brueckner is yet to be questioned over the case and attacked prosecutors in his letter for making statements about him to the press.

Madeleine vanished from a Portuguese holiday apartment where she was staying with her parents Kate and Gerry and twin two-year-old brother and sister in May 2007.

Brueckner is serving a seven-year prison sentence in Oldenburg, Germany, over the rape of an elderly woman in her home in Praia da Luz in 2005 – the same resort where Madeleine disappeared just 18 months later.

Letter includes bizarre cartoon of prosecutors

In the neatly written letter, spanning a single page, the prisoner stated that prosecutors were “unsuitable for office” and “bring shame to the German legal system”.

A bizarre hand-drawn cartoon accompanied the letter, depicting two prosecutors ordering food at a restaurant, with one of the characters saying in speech bubbles: “I’ll take the fillet forensics”, to which the other replies, “Yummy, me too.”

It is believed the cartoon is a reference to investigators, who previously admitting they did not possess any forensic evidence linking Brueckner to the case.

“Charging an accused is one thing,” the letter reads.

“Something completely different – namely, it is an unbelievable scandal – when a public prosecutor starts a public campaign for prejudice before a court case is opened.

“Freedom of expression is not a basic right so that everyone can say and write what they want. Freedom of expression does not protect the majority.

“It protects the minority. It does not protect the most logical, most convincing or most popular views, but rather the outsider position.

“I call on the Brunswick public prosecutors (Hans Christian) Wolters and (Ute) Lindemann to resign from their office.

“Both are proving worldwide through my arbitrary condemnation in the past and through their scandalous pre-denial campaign in the present against me as an innocent person that they are not suitable for an office as a lawyer for the honest and trusting German people and you bring shame onto the judiciary.”

Clairvoyant claims to know where Maddie is buried

Meanwhile, there are reports police will probe a clairvoyant’s claim that Madeleine’s remains are buried in a forest just a few miles from where she vanished.

Michael Schneider has given police the exact coordinates of where he thinks her body is in Portugal and believes she was killed within hours of going missing.

Schneider, who has successfully located the remains of several people, contacted the German equivalent of the FBI – the BKA – just three weeks ago with the claims.

Authorities have since confirmed they would incorporate the information into their investigation.
