HALEIWA, OAHU (HawaiiNewsNow) - The search for three fishermen missing off Oahu's North Shore was suspended at sunset Thursday.
The three -- friends Klint Oshima, 36, Jenson Loo, 30, and Derek Tomas, 30 -- went fishing out of Haleiwa Boat Harbor over the weekend, but never returned.
On Monday, their capsized fishing boat was found about 25 miles offshore.
Coast Guard crews searched more than 18,000 square nautical miles by air and by sea, but found no other sign of the men. On Thursday, the families of the missing men asked the Coast Guard to expand the search to all the waters around Kauai.
"That current headed up towards Kauai is always strong, so it's the parts that we haven't searched yet," said John Lercara, of the U.S. Coast Guard.
Loved ones say the three men were experienced fishermen, and experts say it is possible for people to survive several days in the water.
"Longer chance here in Hawaii due to the warm water temps," Lercara said. "Of course, we look at dehydration and lack of food."
The families of the three fishermen were told Thursday morning that the search would end when the sun went down.
As difficult as that was to hear for Matt Oshima, Klint's younger brother, he understands and is grateful.
"The U.S. Coast Guard, the Navy, there's a lot of private boat owners ... who helped with this search," he said. "It's come to a point where we just want to thank everybody."
The family is still holding out hope that the three men will be found alive, but know the chance of that happening is fading.
