Helmsman Park Kyung-nam identified the third mate as Park Han-kyul. The helmsman who was arrested, 55-year-old Cho Joon-ki, spoke to reporters outside court and accepted some responsibility.
"There was a mistake on my part as well, but the steering had been turned much more than usual," Cho said.
Lee has four decades of experience at sea. He had been captaining ferries for 10 years by the time he was interviewed by the Jeju Today website in 2004, and said he had sailed on ocean freighters for 20 years before that.
But he was not the Sewol's main captain, and worked on the ship about 10 days a month, helmsman Oh Yong-Seok said.
Lee was not on the bridge when the ship began to list. "I gave instructions on the route, then briefly went to the bedroom when it happened," he told reporters.
According to the court, Lee faces five charges, including negligence of duty and violation of maritime law, and the two other crew members each face three related charges.
Lee was required by law to be on the bridge helping his crew when the ferry passed through tough-to-navigate areas, said Yang, the senior prosecutor.
Yang said Lee also abandoned people in need of help and rescue, saying, "The captain escaped before the passengers." Video aired by Yonhap showed Lee among the first people to reach the shore by rescue boat.
Yang said the two crew members arrested failed to reduce speed near the islands and failed to carry out necessary measures to save lives.
It's not clear why the two crew members made the sharp turn, Yang said. He said prosecutors would continue to look into whether something other than the turn could have made the ferry sink, but he added that there were no strong waves that could have knocked down the ferry at the time.
Prosecutors will have 10 days to decide whether to indict the captain and crew, but can request a 10-day extension from the court.
Three vessels with cranes arrived at the accident site to prepare to salvage the ferry, but they will not hoist the ship before getting approval from family members of those still believed inside because the lifting could endanger any survivors, said a coast guard officer, speaking on condition of anonymity, citing department rules.
