ROME (AP) -- A young Moldovan woman who says she was with the captain of the Costa Concordia cruise ship after it rammed into a Tuscan reef emerged as a potential new witness Thursday in the investigation into the captain's actions that night.Crew members and passengers have said Capt. Francesco Schettino ate dinner with a woman in the ship's restaurant Friday night, and Italian news reports have said prosecutors want to interview her.Schettino, who was jailed after he left the ship before everyone was safely evacuated, is under house arrest, facing possible charges of manslaughter, causing a shipwreck and abandoning his ship. Ship owner Costa Crociere SpA says he made an unauthorized deviation from the ship's programmed course that brought him too close to the reefs off the tiny island of Giglio. The ship capsized a few miles away in Giglio's port, forcing the chaotic evacuation of the 4,200 people on board.Eleven people have been confirmed dead and 21 others are still missing.Divers resumed searching for the missing Thursday as a new audiotape emerged of the Concordia's first communication with port officials who inquired about what was wrong. In the tape, an officer insists the ship had only experienced a blackout - comments that came a full 30 minutes after the ship rammed violently into the reef.Dominica Cermotan, a 25-year-old Moldovan hostess who said she was working for Costa on the Concordia, said on her Facebook page that she wasn't on duty the night of the grounding but was with Schettino, other officers and the cruise director on the bridge. She said she was called to help with translations of instructions for how the small number of Russian passengers should evacuate.\We were looking for them
