I put this into the Lounge as I only have a german language link.
The story over years in short. This is about Markus Gäfgen who hijacked and murdered a boy and then demanded ransom.
He was caught by police who were sure he is the hijacker but he did not admit to the crime and did not give the location of the boy. A police officer then threatened him with torture in the hope to save the boy. Gäfgen admitted under the threat and led police to the boy. He could not be saved as he had been dead a while already.
The police officer was dismissed, charged, and given a suspended sentence for the torture threat.
The murderer was sentenced to life for murder. The court decided the admission was under threat and could not be used as evidence. However the evidence found at the crime scene was regarded as legitimate and clear evidence of the crime by Gäfgen.
The lawyer of Gäfgen is now trying to overturn the sentence on grounds of illegally acquired evidence with the European Court of Human Rights.
I sure hope he rots in jail.
