Summary based on the NamUs case record (MP103572) and 2 other sources
Kerry O'Brien, age 52, was last seen on April 4, 2023, along with her husband Frank O'Brien and a family friend, William Gross. The three experienced sailors were aboard their 44-foot vessel, *Ocean Bound*, and were traveling from Mazatlán, Mexico, to San Diego. They planned a brief stop in Cabo San Lucas on April 6 for supplies but never arrived. The last known communication from the group occurred on April 4.

Search efforts, involving both the U.S. Coast Guard and the Mexican Navy, covered over 200,000 square miles but failed to find any trace of the vessel or its occupants. Despite extensive air and sea searches, no evidence has emerged to indicate what may have happened. Adverse weather conditions were reported in the area, but the sailors' families remained hopeful due to their extensive experience. Unfortunately, after several days, the search was suspended without any breakthroughs.

The disappearance of Kerry, Frank, and William remains a mystery, and the case has deeply affected their families and the sailing community. The authorities continue to ask for any information that could help resolve the case.
