Madeleine McCann suspect investigated over rape and murder of German boy, 13, whose body was mutilated

GERMAN authorities are probing if the main suspect in the Madeleine McCann investigation is linked to the rape and murder of a 13-year-old boy, it is reported.

According to German newspaper Frankfurter NeuerPresse, prosecutors are investigating if Christian B has any connections to the killing of Tristan Brübach, who was murdered and mutilated in March 1998.

He was found dead in a tunnel after being brutally maimed.

The young boy had his throat cut and parts of his body removed in a sickening attack.

Earlier this month German police named Christian B, 43, as a suspect over the disappearance of Madeleine, who they believed to be dead.

The suspect was swiftly identified as a convicted rapist, drug dealer and child sex offender, ­currently in jail in Germany.

COPS PROBE LINK TO MISSING BOY

Noah Kruger, chief prosecutor in Frankfurt, told German newspaper Bild: "We are checking whether there are any connections between the two cases.

"In itself, however, this is not unusual, but routine.

"The sequence of events and the E-fit from the Tristan case could be similar.”

Christian B was convicted last year for the 2005 rape of a 72-year-old tourist in Praia da Luz and sentenced to seven years. At the time of the conviction he was in jail for drug offences.

He is now being investigated in connection with the disappearance or murders of at least six children – including Madeleine, three, who went missing in the Algarve in 2007.

The sequence of events and the E-fit from the Tristan case could be similar.

According to Germany's Federal Criminal Police Office  (BKA), Tristan was beaten and gagged before his death, and his body showed severe bruising.

He was murdered with a deep cut through the throat and the killer also cut flesh from his body. 

Parts of the body that were cut off were never found.

Three boys reportedly saw Tristan being murdered and mutilated in the tunnel from a distance.

The description they gave to cops of the perpetrator was reportedly similar to that of Christian B.

His killer was described as aged 20-30 years old, unkempt, slim and with dark blonde, greasy hair.

'CONCRETE EVIDENCE'

It comes after German prosecutors wrote to Madeleine's parents Kate and Gerry McCann to to tell them their daughter is dead.

They have “concrete evidence” suspect Christian B killed Madeleine but cannot yet reveal details.

The message makes it clear they have no doubts that the couple’s daughter is dead and suspect Christian B is responsible.

But it says revealing the evidence too soon might damage the chances of him ever coming to trial.

Prosecutor Hans Christian Wolters Wolters said today: “We have written to the McCanns to tell them Madeleine is dead and explaining we just ­cannot say what the evidence is.

“We have concrete evidence that our suspect has killed Madeleine.

“British police have been informed but don’t have all the evidence we have. The results of our investigation have been shared but not every detail has been passed to Scotland Yard.

“I don’t think the McCanns have been informed of all the details but they know the results.”

The McCanns’ Portuguese lawyer Rogerio Alves has called on German police to share the evidence they claim to have about her death.

Mr Wolters said: “I understand what the McCann family lawyer is saying. I sympathise with the parents but if we reveal more details to them it might jeopardise the investigation.

“I know it would be of relief to the parents to know how she died but it would hamper the investigation if we give away too much information.
