SAN JUAN, Puerto Rico (AP) — Police in the Cayman Islands say they suspect a Canadian cruise ship passenger who recently vanished may have fallen off the boat as search crews scour waters around the British Caribbean territory.

Police said Wednesday that authorities believe the unidentified 65-year-old man may have fallen around dawn on Tuesday just northwest of Grand Cayman.

The man's wife reported him missing Tuesday morning as the Royal Caribbean Cruises ship prepared to dock at George Town Harbor.

Tracy Quan is a spokeswoman for Miami-based Royal Caribbean. She said Wednesday that the Independence of the Seas ship has departed and that the man's wife disembarked in Grand Cayman.

The man is the second Canadian passenger that has gone missing from a Royal Caribbean ship in recent days.
