Italian authorities say they have identified another person killed when the Costa Concordia cruise ship capsized last month -- a German woman named Siglinde Stumpf.

Stumpf was identified Wednesday by the prefecture in the city of Grosseto, a body that represents the Rome government.

Strumpf is the 17th person whose body has been identified following the grounding of the cruise ship on Jan. 13.

The Grosseto prefecture now lists 15 others as still missing. The search for them, however, has been hampered by rough seas and a decision not to keep looking within the submerged hulk of the ship, which is considered too dangerous now.
