A New York State Police investigator says a woman accused of fatally sabotaging her fiancé's kayak on the Hudson River told an investigator she removed a plug on his kayak and manipulated his paddle.

Authorities say Angelika Graswald removed a drain plug from Vincent Viafore's kayak in April 2015 and pushed a floating paddle away from him after his kayak capsized.

A Cornwall police officer testified Monday Graswald appeared calm and emotionless after she was rescued.

State police senior investigator Aniello Moscato also testified Graswald told another investigator she had pulled a plug on the kayak and manipulated the ring on Viafore's paddle.

Neither prosecutors nor the defense can comment due to a gag order.

The defense maintains Viafore's death was accidental, and Graswald has denied murder and manslaughter charges.
