Three Mexican Navy boats and a helicopter were searching the waters off the Caribbean resort of Cancun on Friday for an American woman who reportedly fell from a cruise ship, authorities said. A US Coast Guard search-and-rescue crew using a Falcon jet halted its efforts to find 36-year-old Jennifer Feitz late Friday, but will resume early Saturday morning using a larger C-130 aircraft, said Petty Officer Third Class Nick Ameen. Feitz's husband reported her missing from the Norwegian Pearl cruise ship just before 5 a.m. EST Friday. Her hometown was not available. Mexico's Fifth Naval Regional Command said in a statement that by late Friday it had found no sign of Feitz and was having to deal with "adverse conditions" and strong waves in the search taking place just over 17 miles (27 kilometers) east of Cancun.
