The U.S. Coast Guard says it has suspended its search for three fishermen who went missing off Hawaii last weekend.

The Coast Guard says rescuers searched more than 27,000 square miles over four days. The search extended nearly 100 miles north of Oahu and as far west as Kauai.

Rescuers found the men's boat overturned about 25 miles off Oahu's North Shore on Monday. Jensen Loo, Clint Oshima and Derek Tomas were reported missing late Sunday when they didn't return from a fishing trip.

The Coast Guard said Thursday that it used an airplane, helicopter and two ships for the search. The Navy sent an airplane and helicopter while the Marine Corps sent a helicopter to help. Firefighters on personal watercraft and in a helicopter joined the effort.
