US, Mexico officials search for 3 US sailors missing for 11 days, were on way to San Diego

The Mexican Navy and the United States Coast Guard are searching for three U.S. sailors who have been missing for 11 days.

The sailors – identified as Kerry O’Brien, Frank O’Brien and William Gross – were last heard from on April 4, the U.S. Coast Guard said in a press release Friday. At the time, they were near Mazatlán, Mexico, a city in the coastal state of Sinaloa.

When the three left Mazatlán, they were headed to San Diego. The sailors planned to stop in Cabo San Lucas on their way – "for provisions and to report in" on April 6, the U.S. Coast Guard said.

There is no record of the three Americans arriving in Cabo San Lucas or the group providing a report of their location, the Coast Guard said.

Authorities have also not received any sightings of the group or the 44-foot LaFitte boat, named "Ocean Bound," that they were sailing with.

"Search and rescue coordinators have contacted marinas throughout Baja, Mexico, with negative sightings of the vessel," the Coast Guard wrote. "Urgent marine information broadcasts have been issued over VHF radio requesting all mariners to keep a lookout for the missing persons and vessel."

The Mexican Navy is searching for the sailors with the assistance of the U.S. Coast Guard. Anyone with information about the "the whereabouts of Kerry O’Brien, Frank O’Brien and William Gross or the sailing vessel Ocean Bound" is asked to contact authorities.

According to ABC News, traveling from Mazatlán to Cabo San Lucas by boat requires a more than 200-mile sail across the southern Gulf of California.
