Authorities continue to look for a kayaker who's been missing since capsizing in the Hudson River over the weekend.

Police say 46-year-old Vincent Viafore and his fiancee, 35-year-old Angelika Graswald, launched from Plum Point on Sunday and then kayaked to Bannerman's Island. Viafore's kayak capsized in rough waters during sudden bad weather.

Police say Graswald was able to call 911 before panicking and falling into the water herself.

She was rescued by a boater, but her fiance, who police say wasn't wearing a life jacket, is presumed dead.
