Cruise Ship Disaster: 6th Body Found Jan. 16, 2011 - A sixth body has been found in the wreckage of the Costa Concordia cruise ship that capsized off the coast of Tuscany as rescue workers continue searching for survivors in the part of the ship that is above water. The sixth body to be found on the cruise ship Costa off Giglio is still unidentified, though it has been confirmed by Italian news outlet Ansa that the man was a passenger on the ship. The man was found on the second deck in a part of the ship which was not flooded by water. He had his life vest on. Sixteen people are still unaccounted for after the Costa Concordia, which was carrying 4,234 passengers and crew, hit rocks Friday evening near Giglio, a small island off the coast of Tuscany. The bodies of two passengers found wearing life jackets aboard the ship were identified Sunday, officials said. Both passengers were elderly men -- one Italian, the other Spanish. The bodies were found earlier Sunday near a gathering point in the submerged part of the luxury liner. "While the investigation is ongoing, preliminary indications are that there may have been significant human error on the part of the ship's master, Captain Francesco Schettino, which resulted in these grave consequences," Costa Cruises said in a statement. The route of the vessel appears to have been too close to the shore, and in handling the emergency the captain appears not to have followed standard Costa procedures. Experts are still analyzing the ship's black box, which has already revealed a one-hour lag between the time of the impact on the rocks at 9:45 p.m. local time Friday and the ship's alarm call to the coast guard at about 10:43 p.m. Investigators suspect Schettino tried to maneuver the ship before alerting coast guard, the Italian news outlet Ansa reported. Schettino is in custody, facing possible charges of manslaughter and abandoning his ship. Ten passengers and six crew members are still unaccounted for. The number was reduced from an earlier estimate of 40 unaccounted for. The U.S. embassy in Rome estimates 120 Americans were on board the ship, of which 118 have been accounted for. "Our immediate priority is to account for all passengers and crew, and to secure the vessel to ensure that there are no environmental impacts," Costa Cruises said in a statement. We have engaged the services of a top specialized salvage company to develop an action plan and help establish a protection perimeter around the ship. The incident began with a loud bang followed by a blackout just as passengers were having dinner. Minutes later, an announcement from the crew said it was merely an electrical problem. But with the ship tilting, many passengers ignored their orders and scrambled to the deck. Vacationers reported the crew did not want to lower the lifeboats. Many reported forcing their way on against orders. Some were lowered, but not everyone got on. By 11 p.m., the ship was tilting too much to its side and many lifeboats couldn't be lowered. Many of the ship's occupants jumped in to the icy waters to make a swim for it, and at least 50 people had to be airlifted by helicopter. Mark and Sarah Plath of Little Rock, Ark., awoke to an announcement just before 11 p.m. saying there was a power outage but not to worry about it. Using their iPhone's level app, the couple soon discovered the ship was tilting 23 degrees. When they went outside, they found about 500 people on the fourth floor deck. "We were trying to get outside," Mark Plath told ABC News. It was difficult to stay in control because so many people were upset. "We were moving really fast and so Mark said, 'We've got to jump,'" Sarah Plath said. The couple jumped and swam to nearby rocks. Lynn Kaelin of Seattle told ABC News the ship's hallways were so crowded "We couldn't see where we were going. "He said 'take my baby,'" Georgia Ananias said, covering her mouth with her hand as she teared up. Giuseppe Romano, a 57-year-old Carabinieri on the cruise, said, "We lived apocalyptic scenes. Immediately afterwards I with other men started taking people off the ship. Mike van Dijk, a 54-year-old from Pretoria, South Africa, said crew members delayed lowering the lifeboats even though the ship was listing badly. "We had to scream at the controllers to release the boats from the side," van Dijk said. ABC News' Michael S. James, Mark Mooney and Katie Moisse, and The Associated Press contributed to this report.
