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.

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 twelve-foot boat sank in rough surf off the coast of Del Mar, leaving approximately a dozen people in the water.
