A 15-year-old boy was rescued Monday after spending days clinging to an overturned fishing boat in the Bering Sea near Alaska’s St. Lawrence Island, authorities said. Two of his relatives died in the incident. The group had left the island Friday aboard an 18-foot fishing vessel and was expected to return early Sunday. When the boat failed to come back, authorities began a search Sunday evening. A Coast Guard aircrew located the boy on top of the capsized vessel Monday afternoon. Rescuers lowered a life raft and survival equipment, then coordinated with the nearby vessel Northwest Explorer to bring him aboard. The teenager had symptoms of hypothermia after his time in the icy water, according to the Coast Guard. The bodies of the two other boaters were later recovered. The survivor’s brother, Darren Toolie-Noongwook, identified him as Parker and said the family works in commercial fishing and is accustomed to spending long periods on the water. He said Parker reported that the boat’s motor became tangled in fishing line. The vessel later overturned in rough weather. According to Toolie-Noongwook, Parker and a cousin initially climbed onto the overturned boat. The cousin eventually panicked and jumped into the water, swimming only a short distance before drowning. Parker remained on the vessel alone and prayed while waiting for help. “He said he believed he was going to make it. He believed that he was gonna be found and he was gonna be safe, and it happened,” Toolie-Noongwook said. Rear Adm. Bob Little, commander of the Coast Guard’s Arctic district, expressed condolences to the families and communities affected by the deaths. He credited the Northwest Explorer, federal and state agencies, village first responders and other mission partners with helping save the teenager. The rescue underscores the dangers faced by boaters in the Bering Sea, where cold water and rapidly changing weather can turn a mechanical problem into a life-threatening emergency. Authorities have not publicly released additional details about the identities of the two people who died.
