The suspect, who has been identified by media as Christian Brueckner, is currently serving a seven-year prison sentence in Germany for a rape he committed in Portugal in 2005.
In the German legal system, a court must decide after it receives an indictment from prosecutors whether to take a case to trial.
The Braunschweig state court said in April its supposed responsibility for the case had been based on the suspect’s last residence before he went abroad and then to prison. But it said that wasn’t valid, because the suspect produced evidence of a later residence in the neighbouring state of Saxony-Anhalt, where he was registered as the owner of a property that he kept after going abroad.
However, on Tuesday the higher regional court said that the last domestic residence of the accused can be determined to be in Braunschweig on the basis of several different indications and proofs — in particular, earlier statements of the accused, dpa reported.
