The Latest Twist in the Alleged Kayak Murder on the Hudson River

— -- A body was found this past weekend near the location where a man disappeared after his kayak capsized on the Hudson River in New York State, authorities said.

Vincent Viafore, 46, disappeared last month while he was kayaking with his fiancee, Angelika Graswald, 35, authorities said. About two weeks later, prosecutors charged Graswald with second-degree murder.

The pair, both of Poughkeepsie, N.Y., were kayaking together in April, authorities said, when Viafore's kayak filled with water, causing it to capsize.

As the kayak case continues, here is what authorities have said so far:

The kayaking trip:

New York State Police initially said rough water and strong winds caused Viafore's kayak to overturn.

Graswald, a Latvian national, called 911, according to police, who initially said that she tried to help him. While trying to help her fiance, she fell out of her kayak, police said, but was later found by a boater and rescued. Police noted at the time of the incident that Graswald was treated for hypothermia at a local hospital and released.

Then, prosecutors said last month that Graswald admitted to investigators that she tampered with Viafore's kayak so that it would take on water.

Prosecutors said Graswald also told police that she watched Viafore struggle in the Hudson's icy waters for several minutes before he went under.

Prosecutors said Graswald admitted to New York State Police it "felt good knowing that he was going to die," and implied that "this was her only way out."

Angelika Graswald charged with murder:

About two weeks after the incident, police charged Graswald with second-degree murder.

Her motive, prosecutors said, was two life insurance policies that could benefit her for a total of about $250,000. Graswald even "talked about what she could possibly do with the money," prosecutors said.

Graswald's lawyer has said he plans to challenge the alleged confessions.

"We're going to find out whether they indeed happened, whether they were voluntary or forced," Graswald's attorney, Richard Portale, said of the alleged confessions reported by prosecutors. "And it's all going to come out."

Graswald has not yet entered a plea. Her bail has been set at $3 million.

A body in the Hudson:

This Saturday, a body was found in the Hudson River near where Viafore disappeared.

New York State Police said the body was pulled from the river near West Point and was taken to the Orange County Medical Examiner for an autopsy and identification. Police released no identifying information about the body.

Viafore's family declined to comment to ABC News.
