'Ardennes goblin' Michel Fourniret was accused by his ex-wife of raping and killing Estelle Mouzin, a 9-year-old girl who went missing in 2003, shocking France.

Estelle Mouzin went missing in Guermantes, nearly 30 kilometers east of Paris, on January 9, 2003 while on the way home from school.

In the latest statement, Monique Olivier, Fourniret's ex-wife and who is serving a life sentence for his accomplice murder, accused him of kidnapping the schoolgirl Mouzin.

"Investigations have to be conducted to find out where the body is," Delgenes said.

Prior to that, Fourniret, 77, began serving a life sentence in May 2008 for killing seven young girls and women.

In March, Fourniret, who became known as the "Ardennes Goblin", confused police by admitting "someone who is no longer there is my fault", and said that the body was probably in Ardennes.

Fourniret was considered a suspect for the first time in 2006. Detectives found Mouzin's photo on his computer and the white truck he was driving in the area where the girl was missing.

Fourniret repeatedly stated that he was not involved in the Mouzin disappearance and said he was at home in Sart-Custinne, in the south of Belgium, bordering France, on the day she disappeared.

Fourniret was also charged with the murder of Joanna Parrish, a 20-year-old British schoolgirl at the University of Leeds.
