At least three people are dead and nine other people remain unaccounted for, including two children, U.S. Coast Guard spokesperson Hunter Schnabel told USA TODAY. Crews responded to a report of an overturned vessel on the shores of Torrey Pines State Beach off the coast of Del Mar shortly after 6:30 a.m. local time, officials told KABC-TV.

A search was underway early Monday after a suspected smuggling boat capsized off Del Mar, killing three people. Early reports indicated nine people were missing from the boat, while four survivors were located.
