An Italian Coast Guard commander testified Monday he thought the captain of the doomed cruise ship Costa Concordia was unaware of the severity of the crisis. Cmdr. Gregorio De Falco said, at the criminal trial of Capt. Francesco Schettino in Grosseto, Italy, he tried without success to persuade Schettino to return to his duties and help passengers leave the sinking cruise ship. Schettino is on trial for multiple counts of manslaughter in the January 2012 shipwreck of the 951-foot, $618 million cruise ship off the coast of Tuscany that killed 32 people. Thousands more of the 4,200 passengers aboard were plunged into the water when the ship ran aground near the coastal town of Giglio and began to sink.
