Authorities have charged a New York woman with murdering her fiance, who has been missing since an April 19 kayaking trip on the Hudson River.

Police believe Angelica Graswald intentionally killed Vincent Viafore, who vanished after his kayak capsized near Cornwall-On-Hudson. Graswald claimed that they both fell out of the kayak and that she couldn’t reach him. But police say she made incriminating comments during questioning.

Graswald was charged with second-degree murder and was jailed without bail.

Meanwhile, Viafore remains missing and is believed to be dead. Police have not released a possible motive in his suspected death.

Troopers said Graswald was wearing a life jacket but they believe Viafore wasn't.

Authorities said they believe Viafore ended up in the river at Bannerman Island, a landmark for its crumbling, castle-like 19th-century arsenal near the river's east shore.

The search for Viafore continues, police said, and they asked boaters, fishermen and hikers to be on the lookout.
