Two of the three people who remain missing after the boat they were on capsized in San Francisco Bay Tuesday afternoon have been identified.

Ralph Boisa said his extended family and a few close friends were on his younger brother’s boat Tuesday afternoon to celebrate the life of his daughter who died over a decade ago and was in her 30s.

His older brother, Clifford, died shortly after being pulled out of the water. Sixteen others were rescued as the cabin cruiser was hit by a wave, took on water, listed heavily to one side and rolled over before sinking. Clifford’s dog also died.

The three people missing are his sister Carol, Clifford’s wife Jackie, and his daughter’s friend, he said.

“We’ve gone through a lot of tragedy over the years,” said Boisa, who lost his other daughter in 1995. He lives in Washington and couldn’t make it for the excursion.

U.S. Coast Guard crews suspended a search for the missing people late Wednesday.

“Suspending a search is one of the hardest parts of our job and our condolences are with the families of all involved,” U.S. Coast Guard Captain Jared S. Toczko said in a statement.

Crews searched more than 814 square miles, according to the Coast Guard, and suspended their search “pending further developments.”

Toczko previously said he would not dismiss the possibility that those missing could still be alive, though he also said some could have been trapped inside the three-deck, 49-foot cabin cruiser.

“We do know individuals were in the main deck and potentially below deck,” he said. Witnesses described seeing people pounding on glass windows, trapped as the boat sank.

Crews have identified the location the boat sank but have yet to determine how deep it sank, Toczko said.

Once the boat is located, officials will send either divers or an underwater drone to determine if it’s feasible to salvage it, said San Francisco Police Commander Brien Hoo. If the boat is under 120 feet of water, it would be difficult for divers to get to it, he said.

Witnesses reported “rough seas,” San Francisco Fire Department Chief Dean Crispen said, and rescuers said swells reached up to 5 feet. Marine weather conditions, however, didn’t warrant a small craft advisory from the National Weather Service.
