(Reuters) – The U.S. Coast Guard said on Sunday it had called off its search for a woman believed to have fallen overboard from the Carnival Liberty cruise ship off the coast of Galveston, Texas, two days earlier.

The cruise ship alerted the Coast Guard on Friday that Samantha Broberg, 33, was missing and might have fallen overboard about 195 miles (315 km) from the Texas coast.

The Coast Guard said in a statement that its 8th District command center had coordinated 20 hours of aerial searching with a combined search area of more than 4,300 square miles.

Earlier, it said the cruise ship had a video of a woman falling overboard early on Friday morning and had conducted a search for all passengers on board, with Broberg found to be missing.

The Carnival Liberty cruise ship departed Galveston, Texas, on a four-day Mexico cruise on Thursday.
