An American woman was reported missing after failing to return to a Holland America cruise ship on Nov. 20 in Marigot, Saint Martin.

The Caribbean island's Police Force of Sint Maarten (KPSM) is seeking assistance in locating Ann Evans, 55, a missing passenger. 

Evans failed to return to the Rotterdam cruise ship in Port St. Maarten after disembarking a bus in Marigot during an organized island tour, according to authorities.

"During the tour, Ms. Evans disembarked the bus in Marigot, French Saint Martin," the police force said, "but did not return to the bus or to the cruise vessel."
