New indications that the captain of the ship might have veered four miles off course on purpose have come to light as the sister of a waiter on board reportedly posted on Facebook that the ship would soon be moving toward the island.
"In a short period of time the Concordia ship will pass very close -- a big greeting to my brother who finally gets to have a holiday," the Facebook post read.
Italy's La Repubblica newspaper reports that Schettino was heard saying after the last phone call on deck with the port authorities: "My career ends here. They will fire me."
At a news conference Monday, Costa Cruises chief executive officer Pier Luigi Foschi said Schettino had made an unapproved, unauthorized maneuver to change the ship's programmed course.
"We believe it has been a human error here -- the captain did not follow the authorized route, which is used by Costa ships very frequently," Foschi said, "probably more than 100 times a year we travel this route.
"The company will be close to the captain and will provide him with all the necessary assistance, but we need to acknowledge the facts and we cannot deny human error," Foschi told a news conference in Genoa. "He wanted to show the ship, to [go] nearby this island of Giglio, so he decided to change the course of the ship to go closer to the island."
Experts are still analyzing the ship's first black box, which has already revealed a one-hour lag between the time of the impact on the rocks at 9:45 p.m. local time Friday and the ship's alarm call to the coast guard at about 10:43 p.m. Investigators suspect Schettino tried to maneuver the ship before alerting the coast guard, Ansa reported.
Infrared video of the scene aboard the ship as it began to capsize shows people lined up like ants, trying to escape Friday night by climbing down a rope ladder to rescue boats below.
"We were not allowed to deploy any more life boats because the previous one had got stuck to the side of the ship. And it was chaos, because of glass, everything was everywhere," survivor James Thomas told ABC News.
Newly released videos show passengers seated in lifeboats, trying to figure out who was responsible for the accident. One woman is heard saying, "Take pictures, take pictures, it is very important to discover whose fault it is…"
"It was every man for himself," Emily Lau, a passenger from Boston on board the Costa Concordia, said Monday on "Good Morning America."
"The main thing is no one knew how to help because they were never trained. That is the cruise ship's fault," Lau said.
"We had to improvise. There was no instruction," Benji Smith, Lau's husband, told "GMA." "No one was telling us what to do."
