Cruise ship captain may have made 'significant' error, company says

Giglio,
Italy (CNN) -- The captain of the ill-fated Costa Concordia may have
made "significant" errors that led to the vessel's grounding Friday and
subsequent deaths of at least five people, the cruise line said Sunday.

"The
route of the vessel appears to have been too close to the shore, and
the captain's judgment in handling the emergency appears to have not
followed standard Costa procedures," Costa Cruises said in a statement.

The
ship's captain, Francesco Schettino, was detained Saturday for alleged
manslaughter, causing a shipwreck and abandoning ship while passengers
were still on board, chief prosecutor Francesco Verusio told Italy's
ANSA state news agency.

Schettino himself joined Costa Cruises as
a safety officer in 2002 before being appointed captain four years
later, the company said.

First officer Ciro Ambrosio was being detained for questioning on similar charges, prosecutor Verusio said.

Even
with its admission that mistakes were made, the Genoa-based cruise
company -- whose parent firm, Carnival Corp., did not respond Sunday to
requests from CNN for more information -- defended the ship's crew in
the face of criticism.

"It is becoming clear that the crew of the
Costa Concordia acted bravely and swiftly to help evacuate more than
4,000 individuals during a very challenging situation," the company
said, adding all crew members are trained and the passengers earlier
took part in an evacuation drill.

Survivors have described the
scene -- after the ship hit rocks in the island of Giglio, off the coast
of Tuscany, and turned over on its side -- as "chaos."

"It was
just battling, mad scrambles," American student Brandon Warrick said of
the fight to board lifeboats, describing it as "a giant every man for
himself."

His sister Amanda said she feared she was going to die as they waited for up to two hours for rescue.

"Waiting
was definitely the worst. Because we didn't know who was going to be
coming, how much longer we would have to wait," she said.

Authorities have said at least 20 were injured due to the incident, in addition to those killed.

That
death toll includes two elderly people whose bodies were found, with
their life jackets on, near one of the ship's restaurants, Italian Coast
Guard spokesman Capt. Cosimo Nicastro told reporters Sunday.

Hours earlier, crews rescued a ship employee trapped in a ship restaurant.

The
man -- an Italian purser whose name was not released -- was suffering
from hypothermia when rescue crews found him, said Commander Filippo
Marini, a spokesman for the Port Authority of Porto Santo Stefano.

Earlier
Sunday, before the two bodies were found, Giglio Mayor Sergio Ortelli
said at least six ship workers and 11 passengers were still unaccounted
for.

Authorities are reviewing passenger lists to confirm the
exact number of missing people, said Giuseppe Orsina, a spokesman with
the local civil protection agency. Many of those rescued in the early
hours were taken to small churches and other buildings around the island
for shelter. Some were still wearing the pajamas and slippers they had
on as the ship went down.

"These people could be still on the island of Giglio, in private houses or in hospitals," Orsina said.

There were fears the death toll could rise as rescuers searched the ship, which was nearly 50% submerged, authorities said.

Divers
resumed their search Sunday morning for people unaccounted for after
rocks tore a gash in the hull Friday evening. As this effort continued,
questions and criticism continued about what caused the shipwreck and
the adequacy of the response.

Speaking on Italian television, the ship's captain insisted the rocks that the Concordia hit were not marked on his map.

"On the nautical chart, it was marked just as water," Schettino said, adding that the ship was about 300 meters from shore.

But
Nicastro, the Coast Guard spokesman, insisted that the waters where the
ship ran aground were well-mapped. Local fishermen say the island coast
of Giglio is known for its rocky sea floor.

"Every danger in
this area is on the nautical chart," Nicastro said. "This is a place
were a lot of people come for diving and sailing. ... All the dangers
are known."

He said the Coast Guard was investigating why the ship took the course it did.

"We know where the ship was," he said. "We know it was too close to the island. ... We don't know why."

Like a scene out of the film 'Titanic,' chaos consumed listing ship

Italian
prosecutors seized the ship's data recorders Saturday, and expect to
analyze them within days. Costa Cruses said Sunday that it can only
access that information with authorities' permission.

Built in
2006, the Concordia had been on a Mediterranean cruise from Rome with
stops in Savona, Marseille, Barcelona, Palma de Mallorca, Cagliari and
Palermo.

The ship was carrying about 3,200 passengers and 1,000 crew members when it ran aground and began taking on water Friday night.

The
crew kept going because they believed the vessel could continue sailing
normally, said Nicastro, the Coast Guard spokesman. Realizing there was
a significant safety problem, the commander steered the Costa Concordia
closer toward the port of Giglio, he said.

Authorities are looking at why the ship didn't send a mayday during the accident.

Besides
the two elderly people, the dead include two French tourists and a crew
member from Peru, port authorities in Livorno said. One of the victims
was a 65-year-old woman who died of a heart attack, authorities said.

Rescuers
overnight Saturday reached two South Korean passengers who had been
trapped in the ship for more than 24 hours, authorities said.

"It's
a miracle that we found the Korean couple alive, and we hope we'll find
more people," said Nicastro of the Italian Coast Guard.

The
couple, both 29, were found in a cabin after they heard rescuers calling
out and managed to make contact, according to Italy's ANSA news agency.
