By Steve Gorman LOS ANGELES (Reuters) – The U.S. Coast Guard on Monday called off its search for more survivors from a boat that capsized off a rocky shoal near San Diego in what authorities said was an ill-fated migrant-smuggling operation that left three dead and five hospitalized. The 40-foot trawler-style vessel with 32 people aboard overturned and broke apart on Sunday near the Point Loma Tide Pools, part of a federal marine national monument about 20 miles north of the U.S.-Mexico border, authorities said. Officials on Sunday said four people aboard the boat had perished, but the Coast Guard on Monday revised the death toll downward to three, citing information from the San Diego County Medical Examiner’s office.
