A hard disk found at a non -used factory purchased by the main suspect in the Madeleine McCann study contains proof that she is dead, it is said.
German public prosecutors believe that Christian Brueckner killed the three -year -old after she disappeared during a family vacation in Praia de Luz, Portugal, in 2007.
The ride was discovered in 2016 in a non -used factory that Brueckner bought for £ 20,000 in 2008, according to the Sun.
Researchers also found an insurance document that proves that the suspect was at a music festival that he would have known to kill Madeleine.

Witness Helge B claims that Brueckner told him that she “didn't scream”, but questions about his credibility have always remained.
Children's clothing and toys would be in the deserted building next to masks, chemicals and weapons.
The German police also discovered six USB sticks and two memory cards in a wallet. The evidence was detected by a dog in 2016.
In one, the suspect described a mother and daughter outside of a kindergarten, while another spoke about abusing a four -year -old girl.
Skype conversations with other pedophiles were also discovered, including one where he said he “wanted to capture something small and used it for days”.
Child abuse of four and five-year-old girls would also have been found during the searches, and the police have excavated more than 75 swimming costumes, in addition to toys and small bicycles.
A Sat -Navik also showed that Brueckner had been in the Algarve in the years after Madeleine had disappeared.
The claims will be broadcast completely on Wednesday evening in a channel 4 -documentary.
Representatives from Brueckner were contacted for comment.
