The witness who helped relaunch the probe into Madeleine McCann's disappearance has insisted suspect Christian Brueckner is guilty and will 'stay in jail for a long time'.
Helge Busching has broken his 12-year-long silence to stand by his claims to police that the convicted German rapist was behind the infamous abduction in 2007.
The 48-year-old was the first person to go to police with information about Brueckner in 2017, around the tenth anniversary of her going missing.
He says he knows that Brueckner killed the three-year-old, who personally told him several details about events surrounding the disappearance.

When asked by The Sun what he thought of Brueckner, he said: 'One word. Guilty.'
Main suspect Brueckner is currently in jail for drugs offences, and is appealing a seven-year sentence for raping a 73-year-old woman.
Busching, now a recycling worker, was tracked down to a village on the Greek island of Corsica, having remained anonymous since he provided evidence to officers three years ago.
In a statement he gave to officials at the time, Bushin claims Brueckner, 43, told him he was involved in abducting Maddie while they were talking at a kite festival in Orgiva, Spain.
He described the main suspect as a 'German male person, whom I know by the name of Christian', adding how he would 'talk in detail of his knowledge' of his connection with Madeleine McCann.

The then-three-year-old was taken from her family's holiday apartment in Praia da Luz on May 3, 2007, while her parents had dinner in a nearby tapas bar.
Met Police and Portuguese authorities have continued a relentless search for her, but after Brueckner became a suspect in the case, investigating German police claim they have found evidence that Madeleine has been killed.
Her parents Kate and Gerry McCann continue to believe that she is alive.
Busching said he and another friend Manfred Seyferth knew Brueckner from when they all lived in the same Portuguese resort that the McCanns holidayed in.
It is believed Bushing did not have much contact with Brueckner following this, but found himself with his own criminal difficulties.
While under investigation he was put in touch with Operation Grange - the Met Police's team investigating Madeleine's disappearance - where he gave them details about Brueckner.
According to an internal Greek police report, Busching's information was described as 'given voluntarily and without monetary or other consideration'.

It is unclear why Busching waited nearly ten years before telling cops of Brueckner's alleged involvement.
However, Busching, along with Seyferth, did help convict Brueckner last December for the rape of a 73-year-old woman just outside of Praia da Luz two years before Maddie's disappearance.
The American victim had told cops her attacker filmed the attack and appeared to get a thrill out of seeing her begging him to stop.
Busching and Seyferth are said to have stolen a video camera in Brueckner's home while he was in jail for theft. They contacted police after seeing the images and told them it was Brueckner.
