Madeleine McCann German prosecutors say they ‘remain optimistic’ they will crack the case almost 14 years on
GERMAN prosecutors "remain optimistic" the Madeleine McCann mystery will be solved, it's reported.
Hans Christian Wolters said an investigation into suspect Christian B, 44, was running "at full speed" – as the 14th anniversary of her disappearance nears.
Wolters also hopes a new TV documentary will help unearth more clues, the reports.
He told the newspaper: "Even if the public does not notice it much, our investigations in the Maddie case continue to run at full speed.
"We still assume the accused, Christian B, killed Madeleine. Even though the investigation of a case that will be 14 years old in a few days is very difficult after all this time, we remain optimistic and hopeful that we will be able to solve the crime.
"In doing so, we continue to work closely with the Metropolitan Police and the Portuguese law enforcement authorities, regardless of Brexit."
Mr Wolters said in June last year he believed Madeleine was dead and identified convicted paedophile Christian B as a prime suspect.
He is serving seven years for the rape of a 72-year-old woman in Praia da Luz — where two-year-old Madeleine vanished from her family’s holiday apartment on May 3, 2007.
She was in Portugal with her parents Gerry and Kate and her twin siblings.
A Danish-made documentary on Christian B will air in the suspect’s native Germany on April 28.
But a lawyer for Christian B has repeatedly called for police to show their evidence and vowed his client will never face trial over Madeleine.
