SAN JUAN, Puerto Rico - The U.S. Coast Guard has ended a search for a Canadian man who jumped off a cruise ship as it sailed toward Puerto Rico.

Guard crews spent 44 hours searching for 26-year-old Tien Phuoc Nguyen, who leaped from a Royal Caribbean Cruises ship late Saturday. They called off the search Monday afternoon.

Other passengers reported seeing him jump overboard as the cruise ship was east of Mona Island, located between Puerto Rico and the Dominican Republic.

A Royal Caribbean spokeswoman says the ship's cameras have footage of a passenger going overboard.

The FBI is investigating what may have led him to jump on the final night of a weeklong Caribbean cruise with his family.
