The Coast Guard suspended its search Friday night for six crewmen missing from a cargo ship that capsized and sank in heavy seas off the resort island of Nantucket.

Five of the 11 crewmen aboard the 254-foot cargo ship Lloyd Bermuda were pulled from the ocean Thursday. Two of them died, but the other three suffered only minor injuries, authorities said.The Coast Guard said the search for the six missing crewmen was called off after an investigation revealed it was unlikely that anyone made it into either of two life rafts when the ship sank abruptly in rough Atlantic seas Wednesday night.

A preliminary investigation shows a sudden shift in the ship's cargo caused it to capsize.
