Divers on Saturday found a woman's body in the wrecked cruise liner Costa Concordia, raising the death toll to 12, a police official said.
"The body of a woman was found around 13:30 (1230 GMT) and was taken to the mainland. They will have to rely on DNA tests now to identify the victim after a week in the water," he said.
Coastguard divers had discovered the body towards the stern on the fourth of the vessel's 17 decks, eight days after the ship hit rocks and keeled over on to its side off Italy's northwest coast, the official said.
Divers had carried out a search in previously inaccessible parts of the ship below the water line after blowing holes in the side of the vessel with micro-explosives.
Rescue workers are still looking for 20 missing people.
