The child murderer Martin N., known as the "masked man", returns from France to a prison in Lower Saxony.
"An exact date for the return has not yet been set," said a spokesman for the Ministry of Justice in Hanover on Thursday.
Previously, the "Neue Osnabrücker Zeitung" ("NOZ") reported that the now 50-year-old should return to the Celle prison.
The serial killer, sentenced to life imprisonment, was extradited to France earlier this year because the Nantes public prosecutor was investigating him for the murder of a minor.
According to media reports, Martin N. is a suspect in the case of the boy Jonathan, who was kidnapped in 2004 from a school camp in western France.
The body of the child born in 1994 was discovered a few weeks later.
According to the NOZ, there is apparently too little evidence that the German could also have murdered the French boy.
The spokesman for the Lower Saxony Ministry of Justice could not comment on the state of the proceedings in France.
In Germany, the serial offender had sexually abused boys for years and murdered three of them at the age of eight, nine and 13.
Between 1992 and 2001 he crept masked to the beds of his victims in northern Germany at night, often in school camps and camps;
in the Bremen area also in single-family homes.
In 2012, the former student teacher was convicted by the Stade Regional Court.
