Salvage workers found fragments of bone inside the wreck in August during their search for an Indian waiter, Russel Rebello, whose remains were never found.
But the remains might also belong to Maria Grazia Trecharichi, a Sicilian passenger whose decapitated body was recovered in October last year.
The discovery was made less than a week after the wreck was towed to Genoa from the site of the tragedy off the island of Giglio.
Italian media reported at the time that divers had found skull fragments, although this has neither been confirmed or denied by the civil protection agency.
A court in Grosseto, Tuscany, has appointed a forensic expert to identify the DNA of the remains and compare it to blood samples taken from the families of Rebello and Trecharichi, Il Secolo XIX reported on Tuesday.
Work will begin on October 20th and must be completed within two months.
The two were among 32 people who died when the ship capsized off Giglio in January 2012 after its captain, Francesco Schettino, attempted to “salute” the island.
Schettino did not show up in court on Monday for a hearing as part of his ongoing trial on charges of abandoning a shoip, causing a disaster and multiple manslaughter.
