A German prosecutor is "very confident" charges will be brought against suspect Christian B over the disappearance of Madeleine McCann, claiming the public would come to the same conclusion if it "knew the evidence we had".
Hans Christian Wolters says his investigating team does not yet have enough evidence to charge the convicted sex offender, but feels assured by the case being put together. He believes Christian B killed McCann, according to the BBC.
"I can't promise, I can't guarantee that we have enough to bring a charge - but I'm very confident, because what we have so far doesn't allow any other conclusion at all," the prosecutor told the BBC.
He said if the public knew what evidence authorities had, they would "come to the same conclusion as I do". However, he refused to detail what that evidence is as investigators don't want the suspect "to know what we have on him".
After little progress for years, London's Metropolitan Police provided a "significant investigative update" in June, saying a 43-year-old German prisoner had been identified as a suspect in McCann's disappearance.
It later emerged that the man, Christian B, was in prison for drug and sex crimes, including for raping a 72-year-old woman. The man has been linked to other missing children cases and Wolters told the BBC that he may have committed at least three other sex crimes.
McCann was just three years-old in May 2007 when she went missing from an apartment in Praia da Luz in Portugal.
While German authorities believe the girl is dead, British authorities are treating the investigation as a missing persons case. Met Police Commissioner Dame Cressida Dick reiterated last week that there was "no definitive evidence whether Madeleine is alive or dead".
