(Tribune News Service) — The U.S. Coast Guard on Tuesday suspended its search for survivors after a luxury charter fishing boat sank off the coast of Alaska over the weekend, leaving one person dead and four others missing.

The desperate efforts kicked off Sunday evening after the Coast Guard received a call from Kingfisher Charters, a Sitka-based fishing company, alerting them to a boat with five people onboard that did not reach its destination. The 30-foot vessel was last spotted earlier in the day, the agency said in a news release.

By Sunday night, search and rescue teams found one person dead before uncovering the boat, which was partially submerged off Low Island, about 10 miles west of Sitka. Their efforts continued into Monday, but to no avail.

Air and vessel rescue teams combed through a total of 825 square miles over the course of more than 20 hours before they decided to give up just after sunset on Monday. A group of Good Samaritans and volunteers on boats also assisted in the operations.

“Despite our best efforts and those of several partner agencies, we were not able to find the four remaining individuals,” said Darwin Jensen, Captain of the Port Southeast Alaska.

“Suspending a search is never an easy decision. We extend our deepest sympathy to the loved ones during this difficult time,” he said.

The person found dead and the four missing have not yet been publicly identified.
