After an exhaustive operation to locate three missing Americans, the Mexican Navy has suspended search operations, the U.S. Coast Guard said. Kerry O'Brien, Frank O'Brien, and William Gross left Mazatlán, Mexico, on April 4 on the sailing vessel Ocean Bound, a 44-foot La Fitte. The sailors were en route to San Diego, but didn't arrive or make contact during a scheduled stop in Cabo San Lucas. The suspension of search efforts comes after the Mexican Navy, U.S. Coast Guard and Canada conducted more than 281 search hours. According to the coast guard, responders searched more than 200,000 square nautical miles near Mexico's northern Pacific Coast.
