Kerry O’Brien, 52, vanished at sea after last being seen on April 4, 2023, aboard the 44-foot sailing vessel Ocean Bound with her husband Frank O’Brien and family friend William Gross. The three experienced sailors were en route from Mazatlán, Mexico, to San Diego and intended a brief stop in Cabo San Lucas on April 6, but the boat never arrived and the last communication came on April 4.

Searches by the U.S. Coast Guard and the Mexican Navy covered more than 200,000 square miles with air and sea assets, and adverse weather was reported in the area, but no wreckage, the vessel, or the three occupants were found. After several days the coordinated search was suspended without any breakthroughs. The disappearances have left families and the sailing community seeking answers.

If anyone has information about Ocean Bound, its route after April 4, 2023, or sightings in the area, please come forward.
