The Coast Guard has suspended the search for the lone crew member missing from a fishing vessel that sank off Alaska's Aleutian Islands.

Satashi Konno of Japan has been missing since the vessel sank Sunday. Four people died of hypothermia, and 42 survived.

Coast Guard Rear Adm. Gene Brooks says it was a difficult decision to end the search, but there was no sign of Konno. Konno was wearing a survival suit, but officials said survival would have been difficult in the frigid Bering Sea.

When the ship went down, waves were as high as 20 feet and winds reached nearly 30 mph. Investigators believe the vessel's captain took care of the crew first, and that's why there were so many survivors.
