12th body found in cruise ship disaster GIGLIO, Italy, Jan. 21 (UPI) -- Italian divers Saturday discovered the body of a woman wearing a life jacket aboard the capsized Costa Concordi, raising the death toll to 12, officials said. The divers, who got into the ship through a hole opened in the stern, discovered the woman's body on the fourth deck at 1:30 p.m., Italy's ANSA news agency reported. Coast Guard spokesman Cosimo Nicastro said the woman's body was found in a corridor near the rear of the ship, the BBC reported. "The corridor was very narrow, and the divers' lines risked snagging" on objects in the passageway, Nicastro said. A week after the cruise ship ran aground and after hitting a rock in shallow waters off the Tuscan island Giglio Island, 20 people are still missing. As relatives tossed flowers into the sea near the Costa Concordia, rescue workers said they would search the entire ship. But the BBC noted concerns the ship could slip off a ledge into deeper water. Meanwhile, more than 100 passengers who were aboard the Italian cruise ship say they're joining a class-action lawsuit seeking more than $15 million. Costa Cruises Chairman Pier Luigi Foschi this week said the captain deviated from frequently traveled routes. Schettino, 57, is under house arrest, accused of manslaughter, causing a shipwreck and abandoning ship before all passengers were evacuated. Prosecutors he was sailing too close to Giglio on an unauthorized course to perform a "salute" --- a greeting to islanders.
