As of Monday, six of the more than 4,000 passengers aboard the Costa Concordia have been found dead after the luxury
Italian liner ran aground into Italy's coast on Friday night. Another 16 remain unaccounted for.
The ship's captain, Francesco Schettino, was detained Saturday and is being investigated for manslaughter after causing the shipwreck in Giglio, the island on the western coast of Italy, and abandoning ship while passengers were still on board.
The cause of the crash is still unknown, though preliminary indications are that there may have been "significant human error" on Schettino's part.
