SEA OF CORTEZ (CBS SF) — International rescue teams Sunday continued to search for seven people missing from a charter fishing boat that capsized a week ago in ocean waters near Baja, Mexico, a U.S. Coast Guard official said.

A Coast Guard air crew and the Mexican Navy combed 1,019 miles of the Sea of Cortez near Isla San Luis on Saturday, where seven out of 40 passengers who were aboard the Baja Sport fishing boat have not been found. The boat capsized and sank on July 3, according to the Coast Guard.
