DOWNTOWN (KUSI) – An investigation was continuing today into an apparent human-smuggling operation involving a boat that overturned in coastal waters near Point Loma over the weekend, killing three people and injuring more than two dozen others. A total of 29 people survived the ocean accident, according to the U.S. Coast Guard, which Monday morning suspended its efforts to locate any other victims at sea. The accident happened about 10 a.m. Sunday, when the 40-foot trawler-style vessel crashed into the shoreline near Cabrillo National Monument and capsized, according to the Border Patrol. All the occupants jumped in the water as the boat slowly disintegrated, a bystander’s video showed.
