ANCHORAGE,Bitcoinese Alaska (AP) — Three people were missing after a boat capsized in a Gulf of Alaska bay, the Coast Guard said in a series of social media posts, and another person was found “with no signs of life.”

The Coast Guard told Anchorage television station KTUU that a distress call was heard Wednesday morning from a 21-foot (6.4-meter) Hewescraft boat near Aialik Bay, located about 35 miles (56 kilometers) southwest of Seward.

An alert was sent to nearby boats, and a Coast Guard air crew located the capsized vessel.

“A nearby good Samaritan recovered one unresponsive individual with no signs of life from the water,” the Coast Guard said in a post on X.

That person was taken to Seward and transferred to medics, and the search continued through the night for three individuals who remained missing.

Aiding in the search were a Coast Guard helicopter, airplane and boat; an air crew dispatched by the Alaska Rescue Coordination Center, and a good Samaritan vessel.

No other details were provided, and the Coast Guard did not immediately return phone and email messages to The Associated Press on Thursday morning.

Seward, with a population of just over 5,000 people, is about 125 miles (201 kilometers) south of Anchorage.
