The prime suspect in Madeleine McCann’s disappearance could face “triple trials” over any of the sexual offenses he is investigated.
Convicted pedophile Christian Brueckner was named last year as the man police believe kidnapped from her family’s vacation rental in Portugal in 2007.
The officials are also investigating his alleged involvement in three other cases.
Prosecutors have now announced that they are considering a trial that will cover all three of these sex crimes.
Attorney General Hans Christian Wolters said: “If there is sufficient suspicion in several cases, it must be examined whether a joint indictment would be appropriate.”
The first of the three crimes is the rape of a woman in Praia da Rocha in Portugal’s Algarve in 2004.
The 44-year-old Brueckner is also under investigation for the sexual assault of a girl in Portugal in 2007.
The third case concerns the abuse of four children in the Algarve in 2017.
Every trial would take place in the German city of Braunschweig, where the investigation is centered and where Brücker used to run a kiosk.
German authorities said last week they believe Madeleine was killed shortly after her abduction in the Algarve resort of Praia da Luz, Portugal.
Prosecutors say phone records are placing Brueckner in town when the British girl went missing.
It has already been speculated that she could have been brought to Germany.
Madeleine disappeared from Rothley, Leics on vacation with parents Kate and Gerry McCann at the age of three.
The family, clinging to hope that she is still alive, celebrated the missing girl’s 18th birthday last week.

The German citizen Brueckner is currently serving a seven-year prison sentence in his home country for raping a 72-year-old American woman in Praia da Luz in 2005.
When asked about the latest potential legal development, his attorney declined to comment.
Brueckner, who protested his innocence in the Madeleine case, was in solitary confinement to protect him from attacks by other prisoners.
Brueckner is under investigation for the 2004 rape of Irish woman Hazel Behan in an apartment in the Algarve.
The second case is a sexual assault on a 10-year-old girl on a beach in Portugal in 2007.
The third is the abuse of four children at a festival in São Bartolomeu de Messines in 2017.
