GIGLIO, Italy (AP) - Unregistered passengers might have been aboard the stricken cruise liner that capsized off this Tuscan island, a top rescue official said Sunday, raising the possibility that the number of missing might be higher than previously announced.
Divers, meanwhile, pulled out a woman's body from the capsized Costa Concordia on Sunday, raising to 13 the number of people dead in the Jan. 13 accident.
Civil protection official Francesca Maffini told reporters the victim was wearing a life vest and was found in the rear of a submerged portion of the ship.
Earlier, Italian authorities raised the possibility that the real number of the missing was unknown because some unregistered passengers might have been aboard. As of Sunday, 19 people are listed as missing, but that number could be higher.
"There could have been X persons who we don't know about who were inside, who were clandestine" passengers aboard the ship, said Franco Gabrielli, a national civil protection official.
Authorities are trying to identify five corpses who are badly decomposed after spending a long time in the water. They have identified the other eight: four French, an Italian, a Hungarian, a German and a Spanish national.
