Unalaska, AK – Four crew members are dead and a fifth is missing after a fishing trawler sank in the Bering Sea on Sunday.

The boat's owner, the Fishing Company of Alaska, has identified the dead as captain Eric Peter Jacobsen, chief engineer Daniel Cook, mate David Silveira and crewman Byron Carrillo. As of early this morning, the Coast Guard was still searching for a fifth crew member, whose name hasn't been released yet.

The 47-member crew of the Alaska Ranger abandoned ship at 5 a.m. Sunday morning 120 miles west of Unalaska Island. That was more than two hours after the Coast Guard received a mayday call from the 184-foot ship. At 2:50 a.m. the crew reported that they had lost control of the ship's rudder and were taking on water, but beyond that there's little information about what exactly happened. Coast Guard Petty Officer Walter Shinn said that when a Coast Guard aircraft returned to the area later in the day, the ship was gone.

The C-130 spotted a line of diesel oil, and it stopped at the point where the ship apparently sunk, he said.

The 42 surviving crew members were rescued by the Coast Guard cutter Munro and the Alaska Ranger's sister ship, the Alaska Warrior. About half of them arrived in Dutch Harbor on the Alaska Warrior just after midnight. That group may have included a crew member who was badly injured when he fell from a Coast Guard helicopter during the rescue. No other details were available about the crew's condition.

As of early this morning the cutter Munro was still on the scene, continuing the search for the missing crew member along with a Jayhawk helicopter. The Fishing Company of Alaska released a brief written statement Sunday night, but several representatives of the company contacted Sunday declined to comment further on the incident. Local media were turned away by personnel at the private dock where the Alaska Warrior arrived this morning.
