JINDO, South Korea (AP) -- There are no names listed as relatives huddle around white signboards to identify bodies from a sunken ferry -- just the slimmest of clues about mostly young lives now lost. Many favored hoodies and track pants. One girl painted her fingernails red and toenails black. Another had braces on her teeth.
As divers increasingly make their way into the ship, including a new entryway through the dining hall Monday, there's been a big jump in the discovery of corpses. And that means that on Jindo, an island near where the ferry sank Wednesday, relatives of the missing must look at sparse details such as gender, height, hair length and clothing to see if their loved ones have been found.
"I'm afraid to even look at the white boards," said Lim Son-mi, 50, whose 16-year-old daughter, Park Hye-son, has not been found. "But because all the information is quite similar, whenever I look at it, my heart breaks."
That's why relatives have already lined up to give DNA samples at the gymnasium where they are staying, to make bodies easier to identify when they are recovered.
With hopes of rescue withered, relatives angrily confronted government officials several times Sunday, furious as what they see as an inadequate response to a disaster that may have claimed more than 300 lives.
The confirmed death toll rose to 64 Monday as prosecutors said they detained four crew members -- two first mates, a second mate and a chief engineer -- whom they suspect of failing to protect passengers. The captain and two crew members were formally arrested earlier, and senior prosecutor Ahn Sang-don said prosecutors will decide within 48 hours whether ask a court for arrest warrants for the newly detained crew.
A transcript released by the coast guard Sunday shows the ship was crippled by confusion and indecision well after it began listing Wednesday.
Many people followed the captain's initial order to stay below deck, where it is feared they remain trapped. About 240 people are still missing. The ferry sank with 476 people on board, most of them students from a single high school.
According to the transcript, about 30 minutes after the Sewol began tilting, a crew member repeatedly asked a marine traffic controller whether passengers would be rescued if they abandoned ship off South Korea's southern coast.
That followed several statements from the ship that people aboard could not move and another in which someone said that it was "impossible to broadcast" instructions.
An unidentified official at Jindo Vessel Traffic Services Center told the crew that they should "go out and let the passengers wear life jackets and put on more clothing."
"If this ferry evacuates passengers, will you be able to rescue them?" the unidentified crew member asked.
"At least make them wear life rings and make them escape!" the traffic-center official responded.
"If this ferry evacuates passengers, will they be rescued right away?" the crew member asked again.
"Don't let them go bare -- at least make them wear life rings and make them escape," the traffic official repeated. "The rescue of human lives from the Sewol ferry ... the captain should make his own decision and evacuate them. We don't know the situation very well. The captain should make the final decision and decide whether you're going to evacuate passengers or not."
"I'm not talking about that," the crew member said. "I asked -- if they evacuate now, can they be rescued right away?"
The traffic official then said patrol boats would arrive in 10 minutes, though another civilian ship was already nearby and had told controllers that it would rescue anyone who went overboard.
Ahn said Monday that a number of Sewol crew members, but not the captain, took part in the conversation.
The cause of the disaster is not yet known, but prosecutors have said the ship made a sharp turn before it began to list.
More than 170 people survived the sinking of the Sewol, which had been on its way from the South Korean port city of Incheon to the southern tourist island of Jeju. The captain took more than half an hour to issue an evacuation order, which several passengers have said they never heard.
The confirmed death toll climbed over the weekend after divers finally found a way inside the sunken vessel and quickly discovered more than a dozen bodies. They had been hampered for days by strong currents, bad weather and low visibility.
