Fourniret denies the latest murder allegations

Lawyers said Monique Olivier says her husband is responsible for the deaths of British student Joanna Parrish and Marie-Angele Domece over 10 years ago.

Fourniret, 62, has confessed to at least eight killings. He has denied the latest allegations.

Parrish and Domece both went missing in the Auxerre region of central France.

Parrish, 21, was working as a teaching assistant in the area. An angler found her body floating in a river in May 1990. French police said that she had been raped and strangled.

Two years earlier, 19-year-old Domece went missing in July on the way from her school to Auxerre station. Her body has not been found.

Accomplice

Monique Olivier is herself in custody, accused of being an accomplice to Michel Fourniret's crimes.

He has already been charged with two murders in Belgium.

He has also been placed under investigation for six murders in France.

Under French law, charges are usually brought only after a judicial investigation has taken place.
