The same thing happened on the Cyrstal Harmony last winter. One of the crew did away with himself and when it found that he was missing the search began. The Coast Guard took over the ship. As a result the ship missed one of the ports. Every once in awhile people disappear and some are never seen again. There was a case wear a girl went missing on a Caribbien cruise. No one ever figured out went happened to her. Pleas from the family went all the way to the White House. It was never found out if she went overboard or ran off with some guy. So it's a mystery, it's easy to go missing in the expanse of the sea and never be found.
