A Minnesota couple is missing from the Costa Concordia shipwreck disaster, and the U.S. Embassy in Italy has requested help in locating them. Jerry Heil, 69, and his wife, Barbara, 70, have not been accounted for, and State Department officials are working with the Costa cruise line and Italian authorities to get more information. The embassy has posted photos of them on its Facebook page. The ship ran aground late Friday, and so far six people have been confirmed dead. The Italian Coast Guard said the number of people missing has risen to 29.
