Lawyers for a man from the Ivory Coast who is serving 16 years in an Italian prison for the 2007 murder of British student Meredith Kercher are seeking a new trial.
Rudy Hermann Guede was convicted of killing Ms Kercher in Perugia, Italy, where she was sharing an apartment with US student Amanda Knox. Guede has denied killing Ms Kercher.
Italian media said the lawyers filed the request on Tuesday, contending their client is innocent.
They also noted Ms Knox and Raffaele Sollecito, who steadfastly proclaimed their innocence, were definitely acquitted last year by Italy’s highest criminal court.
Guede’s conviction ruled he committed homicide “acting with others”, but he is the only one to be definitively convicted of the murder.
It is unclear if a new trial could be granted since he has exhausted his appeals.
