Italian navy divers approach the cruise ship Costa Concordia in the tiny Tuscan island of Giglio, Italy, Tuesday, Jan. 17, 2012. Italian naval divers on Tuesday exploded holes in the hull of a cruise ship that grounded near a Tuscan island to speed the search for 29 missing passengers and crew while the seas remain relatively calm. The search intensified as prosecutors prepared to question the captain, who is accused of causing the wreck that left at least six dead by making a maneuver that the Italian cruise operator said was "unapproved and unauthorized."

ROME (AP) -- Italian officials say they have identified the bodies of an American couple and two German nationals who perished when the Costa Concordia cruise ship capsized.
The bodies of the four passengers were identified Tuesday on the interior ministry's website in a posting by the prefect's office from the Tuscan town of Grosseto.
They were named as Barbara and Gerald Heil of Minnesota -- the sole American victims of the disaster -- and Christina Mathi Ganz and Norbert Josef Ganz of Germany.
The body of an Italian crewman was also identified Tuesday after weeks of DNA testing and other exams.
Divers continue searching the wreck for a female Italian passenger and an Indian crewman missing since the Jan. 13 accident and presumed dead. The two have already been included in the death toll of 32.
