A German serial killer, Martin Ney, has been found guilty by a French court for the abduction and killing of a 10-year-old boy during a school trip in 2004.
Ney, dubbed 'the man in black', was handed another life sentence for the murder and kidnapping of Jonathan Coulom, who disappeared at a school holiday camp in western France.
The 55-year-old, who has always denied the charges, listened impassively as the court in the city of Nantes handed down the verdict.
The boy's body was found weighed down by a concrete block in a pond near the town of Guerande, about 30 kilometres from where he had disappeared.
A former fellow inmate testified that Ney had confessed to the crime, and a psychological expert stated that the defendant displayed no evidence of a psychotic disorder.
Ney was already serving a life sentence in Germany for the murders of three children.
